  1. Pharmaceutical form


  1. Clinical particulars

4.1 Therapeutic indications

Methotrexate is a folic acid antagonist and is classified as an antimetabolite cytotoxic agent.

Methotrexate is used in the treatment of adults with severe, active, classical or definite rheumatoid arthritis who are unresponsive or intolerant to conventional therapy.

Methotrexate has also been used in the treatment of severe, uncontrolled psoriasis, which is not responsive to other therapy.

Methotrexate has been used to produce regression in a wide range of neoplastic conditions including acute leukaemias, non-Hodgkin’s lymphoma, soft-tissue and osteogenic sarcomas, and solid tumours particularly breast, lung, head and neck, bladder, cervical, ovarian, and testicular carcinoma.

4.2 Posology and method of administration


Methotrexate should only be prescribed by physicians with experience in the various properties of the medicinal product and its mode of action.

Dosage for Cancer Treatment


The dose must be adjusted carefully depending on the body surface area if methotrexate is used for the treatment of neoplastic diseases.

Fatal cases of intoxication have been reported after administration of incorrectly calculated doses. Health care professionals and patients should be fully informed about toxic effects.

Oral administration

A test dose of 5 – 10 mg parenterally is recommended, one week prior to therapy to detect idiosyncratic adverse events. Low doses not exceeding 30 mg/m2 on five successive days. Thereafter an interval of at least two weeks is recommended to allow the bone marrow to recover.

Doses in excess of 100 mg are usually given parenterally, when the injectable preparation should be used. Doses in excess of 70 mg/m2 should not be administered without leucovorin rescue (folinic acid rescue) or assay of serum methotrexate levels 24 – 48 hours after dosing.

If methotrexate is administered in combination chemotherapy regimens, the dosage should be reduced, taking into consideration any overlapping toxicity of the other drug components.

Dosage for Psoriasis and Rheumatoid arthritis

Important warning about the dosage of Methotrexate Tablets (methotrexate)

In the treatment of psoriasis and Rheumatoid arthritis, 2.5mg requiring dosing once a week e.g. rheumatologic and dermatological diseases, Methotrexate must only be taken once a week. Dosage errors in the use of Methotrexate Tablets (methotrexate) can result in serious adverse reactions, including death. Please read this section of the summary of product characteristics very carefully.

The prescriber should specify the day of intake on the prescription.


Before starting treatment it is advisable to give the patient a test dose of 2.5–5.0 mg to exclude unexpected toxic effects. If, one week later, appropriate laboratory tests are normal, treatment may be initiated.

The usual dose is 7.5 – 15 mg once a week. Weekly dose may also be administered in three divided doses over 24 hours. For the treatment of severe psoriasis, the total weekly dosage can be raised to 20 – 25 mg administered orally as necessary. Dosage should be adjusted according to the patient’s response and the haematological toxicity.

Rheumatoid Arthritis

In adults with severe, active, classical or definite rheumatoid arthritis who are unresponsive or intolerant to conventional therapy, Methotrexate should be taken as 7.5-15 mg once a week. The planned weekly dose may also be administered in three divided doses over 24 – 36 hours. The total weekly dosage can be raised to 20-25 mg as necessary. Dosage should be adjusted according to the patient’s response and the haematological toxicity.

Paediatric population

Treatment should follow currently valid protocols for children. Safety and effectiveness in children have not been established, other than in cancer chemotherapy.

Use in Elderly:

Methotrexate should be used with extreme caution in elderly patients. A reduction in dosage should be considered due to reduced liver and kidney function as well as lower folate reserves, which occur with increased age.

Use in patients with renal impairment – dose adjustments:

Methotrexate is excreted to a significant extent by the kidneys, and therefore should be used with caution in patients with impaired renal function (see sections 4.3 and 4.4). The health care provider may need to adjust the dose to prevent accumulation of drug. The table below provided recommended starting doses in renally impaired patients; dosing may need further adjustment due to wide intersubject pK variability.

<60Methotrexate must not be administered.

Patients with hepatic impairment

Methotrexate should be administered with great caution, if at all, to patients with significant current or previous liver disease, especially if due to alcohol (see sections 4.3 and 4.4).

Use in a patient with a third distribution space (pleural effusions, ascites)

As the half-life of Methotrexate can be prolonged to 4 times the normal length in patients who possess a third distribution space dose reduction or, in some cases, discontinuation of methotrexate administration may be required.

Special note

If changing the oral application to parenteral administration a reduction of the dose may be required due to the variable bioavailability of methotrexate after oral administration.

Method of Administration


4.3 Contraindications

  • Significantly impaired hepatic function
  • Significantly impaired renal function (creatinine clearance less than 30 ml/min) for methotrexate doses <100 mg/m2, and moderate renal impairment (creatinine clearance less than 60 ml/min) for methotrexate doses >100 mg/m2 (see section 4.2)
  • Pre-existing blood dyscrasias, such as bone marrow hypoplasia, leukopenia, thrombocytopenia or significant anaemia
  • Alcoholism
  • Severe acute or chronic infections and immunodeficiency syndrome
  • Stomatitis, ulcers of the oral cavity and known active gastrointestinal ulcer disease
  • Pregnancy and breast-feeding (see section 4.6)
  • Hypersensitivity to methotrexate or to any of the excipients listed in section 6.1
  • During methotrexate therapy concurrent vaccination with live vaccines must not be carried out
  • Methotrexate should not be used concomitantly with drugs with antifolate properties (e.g. co-trimoxazole) (see section 4.5).

4.4 Special warnings and precautions for use

Methotrexate must be used only by physicians experienced in antimetabolite chemotherapy.

Patients must be appropriately monitored during treatment so that signs of possible toxic effects or adverse reactions can be detected and evaluated with minimal delay.

Especially strict monitoring of the patient is indicated following prior radiotherapy (especially of the pelvis), functional impairment of the haematopoietic system (e.g., following prior radio- or chemotherapy), impaired general condition as well as advanced age and in very young children.

Because of the possibility of severe or even fatal toxic reactions, patients should be extensively informed by the treating doctor of the risks involved (including early signs and symptoms of toxicity) and the recommended safety measures. Patients should be informed that they must notify the doctor immediately if any symptoms of an overdose occur and that the symptoms of the overdose need to be monitored (including regular laboratory tests).

Doses exceeding 20 mg week can be associated with a substantial increase in toxicity, especially bone marrow depression.

Because of the delayed excretion of methotrexate in patients with impaired kidney function, they should be treated with particular caution and only with low doses of methotrexate (see sections 4.2 and 4.3).

Methotrexate should be used only with great caution, if at all, in patients who have a significant liver disease, particularly if this is/was alcohol-related (see sections 4.2 and 4.3).

Skin and mucosal contact with methotrexate injection solution is to be avoided.

Concomitant use of hepatotoxic or haematotoxic DMARDs (disease-modifying antirheumatic drugs, e.g. leflunomide) is not advisable.

Acute or chronic interstitial pneumonitis, often associated with blood eosinophilia, may occur and deaths have been reported. Symptoms typically include dyspnoea, cough (especially a dry non-productive cough) and fever for which patients should be monitored at each follow-up visit. Patients should be informed of the risk of pneumonitis and advised to contact their doctor immediately should they develop persistent cough or dyspnoea. Methotrexate should be withdrawn from patients with pulmonary symptoms and a thorough investigation (including chest X-ray) undertaken to exclude infection and tumours. If methotrexate induced lung disease is suspected, treatment with corticosteroids should be initiated and treatment with methotrexate should not be restarted.

Methotrexate-induced lung diseases such as pneumonitis can occur acutely and at any time during treatment, are not always completely reversible and have already been observed at all doses (including low doses of 7.5 mg/week).

For the treatment of psoriasis, methotrexate should be restricted to severe recalcitrant, disabling psoriasis which is not adequately responsive to other forms of therapy, but only when diagnosis has been established by biopsy and/or after dermatological consultation.

Deaths have been reported in association with the use of methotrexate in the treatment of psoriasis.

Methotrexate should be used with extreme caution in the presence/history of infection, peptic ulcer, ulcerative colitis, debility, and in extreme youth and old age. Use in patients with active gastrointestinal ulcer disease is contraindicated. If profound leukopenia occurs during therapy, bacterial infection may occur or become a threat. Cessation of the drug and appropriate antibiotic therapy is usually indicated. In severe bone marrow depression blood or platelet transfusions may be necessary.

Diarrhoea and ulcerative stomatitis are frequent toxic effects and require interruption of therapy, otherwise haemorrhagic enteritis and death from intestinal perforation may occur.

Following the occurrence of haematemesis, black coloured stools or blood in the stools, treatment must be discontinued.

In addition other conditions leading to dehydration such as emesis, can increase the toxicity of methotrexate due to elevated levels of the active substance. In these cases use of methotrexate should be interrupted until symptoms cease. It is important to determine any increase in active substance levels within 48 hours of therapy, otherwise irreversible methotrexate toxicity may occur.

Because of the possibility of severe and even life-threatening toxic reactions the patient should be fully informed by the attending physician of the risks involved before onset of methotrexate treatment. The patient should be closely monitored throughout the treatment.

Patients should be informed of the signs and symptoms of toxicity, of the need to see their physician promptly if they occur, and the need for close follow-up, including regular laboratory tests for monitoring toxicity.

It should be emphasized to the patient treated for psoriasis that the recommended dose must be taken only once a week. The prescriber should specify the day of intake on the prescription. Patients should be instructed on the importance of adhering to the once-weekly intakes, and that mistaken daily use of the recommended dose has led to fatal toxicity (see Sections 4.2 and 4.9).

Most adverse reactions are reversible if detected early. When adverse reactions do occur, the drug should be reduced in dosage or discontinued and appropriate corrective measures should be taken. If necessary, this includes the use of calcium folinate and/or acute, intermittent haemodialysis with high-flux dialyzer.

Methotrexate should be used with extreme caution in patients with psychiatric disorders. Patients with pleural effusions and ascites should be drained prior to initiation of methotrexate therapy or treatment should be withdrawn.

Before beginning Methotrexate therapy or reinstituting Methotrexate after a rest period, a chest x-ray, assessment of renal function, liver function and blood elements should be made by history, physical examination and laboratory tests. This will include a routine examination of lymph nodes and patients should report any unusual swelling to the doctor.

Patients receiving low-dose methotrexate should:

  • Have a full blood count and renal and liver function tests before starting treatment. These should be repeated weekly until therapy is stabilised, thereafter patients should be monitored every 2-3 months throughout treatment.
  • Patients should report all symptoms and signs suggestive of infection, especially sore throat. Any infections should be attended to, before initiation of methotrexate therapy.

Haematopoietic suppression caused by Methotrexate may occur abruptly and with apparently safe dosages. Full blood counts should be closely monitored before, during and after treatment. If a clinically significant drop in white cell or platelet count develops, methotrexate therapy should be withdrawn immediately and appropriate supportive therapy given (see section 4.8). Patients should be advised to report all symptoms or signs suggestive of infection. Any infections should be attended before initiation of methotrexate therapy.

Methotrexate may be hepatotoxic, particularly at high doses or with prolonged therapy. Liver atrophy, necrosis, cirrhosis, fatty changes and periportal fibrosis have been reported. Risk factors for severe liver damage are e.g. previous liver disease, repeatedly abnormal liver function tests and alcohol consumption. Additional hepatotoxic medicinal products should not be taken during the treatment with methotrexate unless clearly necessary and the consumption of alcohol should be avoided or clearly reduced (see section 4.5).

Diabetic patients who are treated with insulin have increased risk for liver toxicity.

Liver function tests

Particular attention should be given to the appearance of liver toxicity. Treatment should not be instituted or should be discontinued if any abnormality of liver function tests, or liver biopsy, is present or develops during therapy. Such abnormalities should return to normal within two weeks after which treatment may be recommenced at the discretion of the physician.

Check of liver-related enzymes in serum

Temporary increases in transaminases to twice or three times of the upper limit of normal have been reported by patients at a frequency of 13–20 %. In the case of a constant increase in liver-related enzyme, a reduction of the dose or discontinuation of therapy should be taken into consideration. Closer monitoring of liver enzymes is necessary especially in patients taking other liver- or haematotoxic medicinal products (e.g. leflunomide). Further research is needed to establish whether serial liver function tests or determinations of propeptide of type III collagen are appropriate for detecting hepatotoxicity.

Patients with risk factors

These primarily include

– anamnestic alcohol abuse

– persistent increase in liver enzymes

– anamnestic hepatopathy including chronic hepatitis B or C

– familial anamnesis with hereditary hepatopathy

and secondarily (with possibly lower relevance):

– diabetes mellitus

– adiposity

– anamnestic exposure to hepatotoxic medicines or chemicals.

The need of liver biopsy should be evaluated case by case and national recommendations should be followed.


Methotrexate therapy in patients with impaired renal function should be undertaken with extreme caution because impairment of renal function will decrease methotrexate elimination. Impaired renal function may result in methotrexate accumulation in toxic amount or even in additional renal damage. In patients with renal impairment the dose of methotrexate should be reduced.

Renal function should be monitored by renal function tests and urinalyses. If serum creatinine levels are increased, the dose should be reduced. If creatinine clearance is less than 30 ml/min, treatment with methotrexate should not be given. If creatinine clearance is less than 60 ml/min, methotrexate doses >100 mg/m2 not be given (see section 4.2 and 4.3).

Treatment with methotrexate doses of >100 mg/m2 should not be initiated at urinary pH values of less than 7.0. Alkalinisation of the urine must be tested by repeated pH monitoring (value greater than or equal to 6.8) for at least the first 24 hours after the administration of methotrexate is started.

Renal lesions may develop if the urinary flow is impeded and urinary pH is low, especially if large doses have been administered.

Methotrexate may cause renal damage that may lead to acute renal failure. Close attention to renal function including adequate hydration, urine alkalinization by oral or intravenous administration of sodium bicarbonate (5 x 625mg tablets every three hours) or acetazolamide (500 mg orally four times a day), and measurement of serum methotrexate and renal function are recommended.

As methotrexate is eliminated mainly via the kidneys, increased concentrations are to be expected in the presence of renal impairment, which may result in severe adverse reactions.

If there is the possibility of renal impairment (e.g. in elderly subjects), monitoring should take place at shorter intervals. This applies in particular when medicinal products that affect the elimination of methotrexate, or that cause kidney damage (e.g. NSAIDs) or that can potentially lead to impairment of haematopoiesis, are administered concomitantly.

If risk factors such as renal function disorders, including mild renal impairment, are present, combined administration with NSAIDs is not recommended. Dehydration may also intensify the toxicity of methotrexate.

Concomitant use of proton pump inhibitors (PPIs) and high dose methotrexate should be avoided, especially in patients with renal impairment.

Immune system

Methotrexate has some immunosuppressive activity and immunological responses to concurrent vaccination may be decreased. Vaccination with live vaccines is contra-indicated during the therapy.

The immunosuppressive effect of methotrexate should be taken into account when immune responses of patients are important or essential. Special attention should be paid in cases of inactive chronic infections (e.g. herpes zoster, tuberculosis, hepatitis B or C) because of their potential activation.

Methotrexate may trigger tumour lysis syndrome in patients with rapidly growing tumour.

Malignant lymphomas may occur in patients receiving low dose methotrexate, in which case therapy must be discontinued. Failure of the lymphoma to show signs of spontaneous regression requires the initiation of cytotoxic therapy.

Since cases of encephalopathy/ leukoencephalopathy have occurred in cancer patients treated with methotrexate, this cannot be ruled out either for patients with non-cancer indications.

The disappearance of methotrexate from plasma should be monitored, if possible. This is recommended in particular when high, or very high doses are administered in order to permit calculation of an adequate dose of leucovorin (folinic acid) rescue.

Methotrexate given concomitantly with radiotherapy may increase the risk of soft tissue necrosis and osteonecrosis.

In the treatment of rheumatoid arthritis, acetylsalicylic acid, nonsteroidal anti-inflammatory (NSAID) agents, and/or low dose steroids can be continued, although concomitant use of NSAIDs and methotrexate may be associated with an increased risk of toxicity. Steroids may be gradually reduced in patients responsive to methotrexate.

The interactions of methotrexate and other antirheumatic drugs such as gold, penicillamine, hydroxychloroquine, sulfasalazine or cytotoxic agents have not been studied comprehensively, and concurrent use may increase the incidence of adverse reactions.

Concomitant administration of folate antagonists such as trimethoprim/sulfamethoxazole has been reported to cause an acute megaloblastic pancytopenia in rare instances.

In addition, pulmonary alveolar haemorrhage has been reported with methotrexate used in rheumatologic and related indications. This event may also be associated with vasculitis and other comorbidities. Prompt investigations should be considered when pulmonary alveolar haemorrhage is suspected to confirm the diagnosis.

If acute methotrexate toxicity occurs, patients may require treatment with folinic acid. In patients with rheumatoid arthritis or psoriasis, folic acid or folinic acid supplementation may reduce methotrexate toxicity, such as gastrointestinal symptoms, stomatitis, alopecia and elevated liver enzymes.

It is recommended to check levels of vitamin B12 prior to initiating folic acid supplementation, particularly in adults aged over 50 years, as folic acid intake may mask a vitamin B12 deficiency.

Methotrexate may cause adverse urinary tract reactions, such as cystitis and haematuria.

Methotrexate has been shown to be teratogenic – reproductive risk; it causes embryotoxicity, abortion and foetal malformations in humans.

Therefore, the possible effects on reproduction, pregnancy loss and congenital malformations should be discussed with female patients of childbearing age (see section 4.6).

In non-oncologic indications, the absence of pregnancy must be confirmed before Methotrexate tablet is used. If women of a sexually mature age are treated, effective contraception must be used during treatment and for at least six months after.

For contraception advice for men see section 4.6.

If this drug is used during pregnancy for antineoplastic indications, or if the patient becomes pregnant while taking this drug, the patient should be appraised of the potential hazard to the foetus.

Methotrexate has been reported to cause impairment of fertility, oligospermia, menstrual dysfunction and amenorrhoea in humans during and for a short period after the discontinuation of treatment, affecting spermatogenesis and oogenesis during the period of its administration – effects that appear to be reversible on discontinuing therapy.

Radiation induced dermatitis and sun-burn can reappear under methotrexate therapy (recall reaction). Psoriatic lesions can exacerbate during UV-irradiation and simultaneous administration of methotrexate.

Severe, occasionally fatal, dermatologic reactions, including toxic epidermal necrolysis (Lyell’s syndrome) or Stevens-Johnson syndrome have been reported after single or multiple doses of methotrexate.

Methotrexate 2.5mg Tablets contain lactose and patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.

4.5 Interaction with other medicinal products and other forms of interaction

Methotrexate is extensively protein bound and may displace, or be displaced by, other acidic drugs. The concurrent administration of agents such as diphenylhydantoins, acidic anti-inflammatory agents, salicylates, phenylbutazone, phenytoin, barbiturates, tranquilisers, oral contraceptives, amidopyrine derivatives, p-aminobenzoic acid, thiazide diuretics, oral hypoglycaemics, doxorubicin,, tetracyclines, probenicid or sulfinpyrazone or oral hypoglycaemics will decrease the methotrexate transport function of renal tubules, thereby reducing excretion and almost certainly increasing methotrexate toxicity.

Since probenecid and weak organic acids, such as “loop-diuretics” as well as pyrazols reduce tubular secretion, great caution should be exercised when these medicinal products are coadministered with methotrexate.

Concurrent use of other, potentially nephro- hemato or hepatotoxic agents (e.g. sulphasalazine, leflunomide and alcohol) should be avoided. Special caution should be exercised when observing patients receiving methotrexate therapy in combination with azathioprine or retinoids.

Methotrexate in combination with leflunomide can increase the risk for pancytopenia.

Enhancement of nephrotoxicity may be seen if high-dose methotrexate is administered in combination with a potentially nephrotoxic chemotherapeutic agent (e.g. cisplatin).

Antibiotics, like penicillin, glycopeptides, sulfonamides, ciprofloxacin and cefalotin can, in individual cases, reduce the renal clearance of methotrexate, so that increased serum concentrations of methotrexate with simultaneous haematological and gastro-intestinal toxicity may occur.

Oral antibiotics such as tetracyclines, chloramphenicol and non-absorbable broad-spectrum antibiotics may reduce intestinal methotrexate absorption or interfere with the enterohepatic circulation, due to inhibition of the intestinal flora or suppression of bacterial metabolism.

Methotrexate dosage should be monitored if concomitant treatment with aspirin, ibuprofen or indomethacin (NSAID’s) is commenced, as concomitant use of NSAID’s has been associated with fatal methotrexate toxicity.

Hepatic, hematotoxic and nephrotoxic drugs should be avoided.

Vitamin preparations or other products containing folic acid or its derivatives may impair methotrexate efficacy.

Under (pre-) treatment with substances that may have adverse effects on the bone marrow (e.g. sulfonamides, trimethoprim-sulfamethoxazole, chloramphenicol, pyrimethamine), the possibility of marked haematopoietic disorders should be considered.

Co-administration of medicinal products which cause folate deficiency (e.g. sulfonamides, trimethoprim-sulfamethoxazole) can lead to increased methotrexate toxicity. Particular caution should therefore also be exercised in the presence of existing folic acid deficiency.

Acitretin (a treatment for psoriasis) is metabolised to eretinate. Methotrexate levels may be increased by eretinate and severe hepatitis has been reported following concomitant use.

Bone marrow suppression and decreased folate levels have been described in the concomitant administration of triamterene and methotrexate.

Administration of additional haematotoxic medicinal products (e.g. metamizole) increases the probability of severe haematoxic effects of methotrexate.

There is evidence that co-administration of methotrexate and omeprazole prolongs the elimination of methotrexate via kidneys. Co-administration of proton pump inhibitors such as omeprazole or pantoprazole can cause interactions. In combination with pantoprazole, inhibited renal elimination of the 7-hydroxymethotrexate metabolite, with myalgia and shivering, was reported in one case.

Methotrexate may decrease the clearance of theophylline; theophylline levels should be monitored when used concurrently with methotrexate. Excessive consumption of beverages containing caffeine or theophylline (coffee, soft drinks containing caffeine, black tea) should be avoided during methotrexate therapy since the efficacy of methotrexate may be reduced due to possible interaction between methotrexate and methylxanthines at adenosine receptors.

One should be aware of pharmacokinetic interactions between methotrexate, anticonvulsant medicinal products (reduced methotrexate blood levels), and 5-fluorouracil (increased t½ of 5–fluorouracil).

The use of nitrous oxide anaesthesia potentiates the effect of methotrexate on folate metabolism, yielding increased toxicity such as severe unpredictable myelosuppression, stomatitis and neurotoxicity with intrathecal administration. While this effect can be reduced by administering calcium folinate, the concomitant use of nitrous oxide and methotrexate should be avoided (see section 4.2).

Colestyramine can increase the non-renal elimination of methotrexate by interrupting the enterohepatic circulation.

Delayed methotrexate clearance should be considered in combination with other cytostatic medicinal products.

The application of procarbazine during high-dose methotrexate therapy increases the risk of impairment or renal function.

Radiotherapy during use of methotrexate can increase the risk of soft tissue or bone necrosis.

Methotrexate increases plasma levels of mercaptopurine. Combinations of methotrexate and mercaptopurine may therefore require dose adjustment.

Vaccination with a live vaccine in patients receiving chemotherapeutic agents may result in severe and fatal infections (see section 4.3). On account of its possible effect on the immune system, methotrexate can falsify vaccinal and test results (immunological procedures to record the immune reaction). During methotrexate therapy concurrent vaccination with live vaccines must not be carried out (see sections 4.3 and 4.4).

Cytotoxic agents may impair absorption of phenytoin, which may decrease efficacy of phenytoin and increase the risk for exacerbation of convulsions. Risk of toxicity enhancement or loss of efficacy of the cytotoxic drug due to increased hepatic metabolism by phenytoin is possible.

Ciclosporin may potentiate methotrexate efficacy and toxicity. There is a risk of excessive immunosuppression with risk of lymphoproliferation when the combination is used.

Particularly in the case of orthopaedic surgery where susceptibility to infection is high, a combination of methotrexate with immune-modulating medicinal products must be used with caution.

Concomitant administration of levetiracetam and methotrexate has been reported to decrease methotrexate clearance, resulting in increased/prolonged blood methotrexate concentration to potentially toxic levels. Blood methotrexate and levetiracetam levels should be carefully monitored in patients treated concomitantly with the two drugs.

4.6 Fertility, pregnancy and lactation


Methotrexate affects spermatogenesis and oogenesis and may decrease fertility. In humans, Methotrexate has been reported to cause oligospermia, menstrual dysfunction and amenorrhoea. These effects appear to be reversible after discontinuation of therapy in most cases.

In oncologic indications, women who are planning to become pregnant are advised to consult a genetic counselling centre, if possible, prior to therapy and men should seek advice about the possibility of sperm preservation before starting therapy as methotrexate can be genotoxic at higher doses (see section 4.4).

Women of childbearing potential/Contraception in females

Women must not get pregnant during methotrexate therapy, and effective contraception must be used during treatment with methotrexate and at least 6 months thereafter (see section 4.4). Prior to initiating therapy, women of childbearing potential must be informed of the risk of malformations associated with methotrexate and any existing pregnancy must be excluded with certainty by taking appropriate measures, e.g. a pregnancy test. During treatment pregnancy tests should be repeated as clinically required (e.g. after any gap of contraception). Female patients of reproductive potential must be counselled regarding pregnancy prevention and planning.

Contraception in males

It is not known if methotrexate is present in semen. Methotrexate has been shown to be genotoxic in animal studies, such that the risk of genotoxic effects on sperm cells cannot completely be excluded. Limited clinical evidence does not indicate an increased risk of malformations or miscarriage following paternal exposure to low-dose methotrexate (less than 30 mg/week). For higher doses, there is insufficient data to estimate the risks of malformations or miscarriage following paternal exposure.

As precautionary measures, sexually active male patients or their female partners are recommended to use reliable contraception during treatment of the male patient and for at least 6 months after cessation of methotrexate. Men should not donate semen during therapy or for 6 months following discontinuation of methotrexate.


Methotrexate is contra-indicated during pregnancy in non-oncological indications (see section 4.3).

If pregnancy occurs during treatment with methotrexate and up to six months thereafter, medical advice should be given regarding the risk of harmful effects on the child associated with treatment and ultrasonography examinations should be performed to confirm normal foetal development.

In animal studies, methotrexate has shown reproductive toxicity, especially during the first trimester (see section 5.3). Methotrexate has been shown to be teratogenic to humans; it has been reported to cause foetal death, miscarriages and/or congenital abnormalities (e.g. craniofacial, cardiovascular, central nervous system and extremity-related).

Methotrexate is a powerful human teratogen, with an increased risk of spontaneous abortions, intrauterine growth restriction and congenital malformations in case of exposure during pregnancy.

Spontaneous abortions have been reported in 42.5% of pregnant women exposed to low-dose methotrexate treatment (less than 30 mg/week), compared to a reported rate of 22.5% in disease-matched patients treated with drugs other than methotrexate.

Major birth defects occurred in 6.6% of live births in women exposed to low-dose methotrexate treatment (less than 30 mg/week) during pregnancy, compared to approximately 4% of live births in in disease-matched patients treated with drugs other than methotrexate.

Insufficient data is available for methotrexate exposure during pregnancy higher than 30 mg/week, but higher rates of spontaneous abortions and congenital malformations are expected, in particular at doses commonly used in oncologic indications.

When methotrexate was discontinued prior to conception, normal pregnancies have been reported.

When used in oncological indications, methotrexate should not be administered during pregnancy in particular during the first trimester of pregnancy. In each individual case the benefit of treatment must be weighed up against the possible risk to the foetus. If the drug is used during pregnancy or if the patient becomes pregnant while taking methotrexate, the patient should be informed of the potential risk to the foetus.


Patients should not breast feed whilst taking methotrexate.

4.7 Effects on ability to drive and use machines

Central nervous system symptoms, such as fatigue and dizziness, can occur during treatment with methotrexate which may have minor or moderate influence on the ability to drive and use machines.

4.8 Undesirable effects

In general, the incidence and severity of side effects are considered to be related to the dose, the dosing frequency, the method of administration and the duration of exposure.

Most adverse reactions are reversible if detected early. When adverse reactions do occur, the drug should be reduced in dosage or discontinued and appropriate corrective measures should be taken. This includes the use of calcium folinate (see sections 4.2 and 4.4). Methotrexate therapy should only be resumed with particular caution, after careful consideration of the need for treatment and with increased vigilance for the possible recurrence of toxicity.

Most serious adverse reactions of methotrexate include bone marrow suppression, pulmonary toxicity, hepatotoxicity, renal toxicity, neurotoxicity, thromboembolic events, anaphylactic shock and Stevens-Johnson syndrome.

Most frequently observed adverse reactions of methotrexate include gastrointestinal disorders (e.g. stomatitis, dyspepsia, abdominal pain, nausea, loss of appetite) and abnormal liver function tests (e.g. increased Alanine aminotransferase (ALAT), Aspartate aminotransferase (ASAT), bilirubin, alkaline phosphatase). Other frequently occurring adverse reactions are leukopenia, anaemia, thrombocytopenia, headache, tiredness, drowsiness, pneumonia, interstitial alveolitis/pneumonitis often associated with eosinophilia, oral ulcers, diarrhoea, exanthema, erythema and pruritus.

The most relevant adverse reaction is suppression of the haematopoietic system and gastrointestinal disorders.

In the antineoplastic treatment, myelosuppression and mucositis are the predominant dose-limiting toxic effects of methotrexate. The severity of these reactions depends on the dose, mode and duration of application of methotrexate. Mucositis generally appears about 3 to 7 days after methotrexate application, leucopenia and thrombocytopenia follow a few days later. In patients with unimpaired elimination mechanisms, myelosuppression and mucositis are generally reversible within 14 to 28 days.

Adverse reactions for the various systems are as follows:

Skin and subcutaneous tissue disorders:

Exanthema, Stevens-Johnson Syndrome, toxic epidermal necrolysis, erythematous rashes, pruritus, urticaria, photosensitivity, pigmentary changes, erythema multiforme, onycholysis, increased pigmentation, petechia, allergic vasculitis, hidradenitis, alopecia, depigmentation, ecchymosis, telangiectasia, acne, furunculosis, painful damage to psoriatic lesions, skin ulceration, herpetiform eruptions of the skin, hyperpigmentation of the nails and acute paronychia.

The recall phenomenon has been reported in both radiation and solar damaged skin. Lesions of psoriasis may worsen with concomitant UV therapy. Radiation dermatitis and sunburn may be “recalled”.

Blood and the lymphatic system disorders:

Megaloblastic anaemia, hematopoietic disorders, eosinophilia, lymphoproliferative disorder (partly reversible), lymphadenopathy, bone marrow depression (especially at high-dose of methotrexate) is most frequently manifested by thrombocytopenia (which are usually reversible), neutropenia, leukopenia, pancytopenia, agranulocytosis, anaemia, aplastic anaemia, immunosuppression, lymphoproliferative disorders (frequency very rare) or any combination may occur. Infection or hypogammaglobulinaemia, haemorrhage from various sites. Bone marrow depression may lead to decreased resistance to infection and sepsis.

Gastrointestinal disorder:

Mucositis, stomatitis, gingivitis, hematemesis, melena, pancreatitis, enteritis, gastrointestinal ulceration (including oral ulcers) and bleeding, malabsorption, toxic mega-colon, dyspepsia, abdominal pain, anorexia, nausea, vomiting, diarrhoea.

Gastrointestinal disorders frequently require dosage adjustment. Ulcerative stomatitis and diarrhoea require interruption of therapy; otherwise hemorrhagic enteritis and death from intestinal perforation may occur.

Hepatobiliary disorders:

Hepatic toxicity resulting in increase of transaminases (ASAT, ALAT), alkaline phosphatase and bilirubin, decrease in serum albumin, acute hepatitis, periportal fibrosis or hepatic cirrhosis, hepatic failure, fatty degeneration of liver, reactivation of chronic hepatitis or death.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product.

4.9 Overdose

Cases of overdose, sometimes fatal, due to erroneous daily intake instead of weekly intake of oral methotrexate have been reported. In these cases, symptoms that have been commonly reported are haematological and gastrointestinal reactions.

The toxicity of methotrexate affects mainly the haematopoietic organs. Calcium folinate neutralises effectively the immediate toxic effects of methotrexate. Parenteral calcium folinate therapy should be started within one hour after the administration of methotrexate. The dose of calcium folinate should be at least as high as the dose of methotrexate received by the patient.

Symptoms of an overdose are mainly the same as the undesirable effects, but stronger.

Leucovorin is a specific antidote for methotrexate and, following accidental overdosage, should be administered within one hour at a dosage equal to, or greater than, the methotrexate dose. It may be administered by i.v. bolus or infusion. Further doses may be required. The patient should be observed carefully and blood transfusions, renal dialysis and reverse barrier nursing may be necessary.

In post-marketing experience, overdose with methotrexate has generally occurred with oral and intrathecal administration, although intravenous and intramuscular overdose has also been reported.

Cases of overdose have been reported, sometimes fatal, due to erroneous daily intake instead of weekly intake of oral methotrexate. In these cases, symptoms that have been commonly reported are hematological and gastrointestinal reactions. For example, leukopenia, thrombocytopenia, anemia, pancytopenia, bone marrow suppression, mucositis, stomatitis, oral ulceration, nausea, vomiting, gastrointestinal ulceration, gastrointestinal bleeding. In some cases, no symptoms were reported. There have been reports of death following chronic overdose in the self-administered dosage for rheumatoid arthritis and psoriasis (see Sections 4.2 and 4.4). In these cases, events such as sepsis or septic shock, renal failure, and aplastic anaemia were also reported.

In cases of massive overdose, hydration and urinary alkalisation may be necessary to prevent precipitation of methotrexate and/or its metabolites in the renal tubules. Neither haemodialysis nor peritoneal dialysis has been shown to improve methotrexate elimination. Effective clearance of methotrexate has been reported with acute, intermittent haemodialysis using a high flux dialysator. Observation of serum methotrexate concentrations is relevant in determining the right dose of calcium folinate and the duration of the therapy.

Treatment measures for methotrexate overdosage can be discontinued when the serum methotrexate level has fallen below the level of 5×10-8 M (10) (see section 4.4).

  1. Pharmacological properties

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Immunosuppressive agents

Mechanism of action

Methotrexate is a folic acid antagonist and its major site of action is the enzyme dihydrofolate reductase. Its main effect is inhibition of DNA synthesis but it also acts directly both on RNA and protein synthesis. Methotrexate is a phase specific substance, the main effect being directed during the S-phase of cell division.

The inhibition of dihydrofolate reductase can be circumvented by the use of leucovorin (folinic acid; citrovorum factor) and protection of normal tissues can be carried out by properly timed administration of leucovorin calcium.

5.2 Pharmacokinetic properties


Orally administered, the absorption of methotrexate seems to be dose-dependent. Peak serum levels are reached within 1 to 2 hours. Generally, at doses of 30 mg/m2 or less, methotrexate is absorbed rapidly and completely. The bioavailability of orally administered methotrexate is high (80–100 %) at doses of 30 mg/m2 or less. Saturation of the absorption starts at doses above 30 mg/m2 and absorption of doses exceeding 80 mg/m2 is incomplete. After parenteral injection, peak serum levels are seen in about one half this period. After intramuscular injection, peak serum concentrations occur in 30 to 60 minutes.

About one half of absorbed methotrexate is reversibly bound to serum protein but is readily distributed in tissues. Excretion takes place mainly via the kidneys. Approximately 41 % of the dose is excreted unchanged in the urine within the first six hours, 90 % within 24 hours. A minor part of the dose is excreted in the bile of which there is pronounced enterohepatic circulation.

The half-life is approximately 3–10 hours following low dose treatment and 8–15 hours following high dose treatment. If the renal function is impaired, the concentration of methotrexate in serum and in tissues may increase rapidly.

Methotrexate does not enter the cerebrospinal fluid at oral or parenteral therapeutic doses. However, cytotoxic concentrations (>10-7 M) can be achieved in the CSF with high doses (>500 mg/m2). When high drug concentrations are indicated, direct intrathecal administration should be used.

5.3 Preclinical safety data

Chronic toxicity studies in mice, rats and dogs showed toxic effects in the form of gastrointestinal lesions, myelosuppression and hepatotoxicity. Animal studies show that methotrexate impairs fertility and is embryo- and foetotoxic. Teratogenic effects have been identified in four species (rats, mice, rabbits, cats). In rhesus monkeys no malformations occurred. Methotrexate is mutagenic in vivo and in vitro. There is evidence that methotrexate causes chromosomal aberrations in animal cells and in human bone marrow cells, but the clinical significance of these findings has not been established. Rodent carcinogenicity studies do not indicate an increased incidence of tumours.

  1. What methotrexate tablets ip are and what they are used for

Methotrexate Tablets IP are one of a group of medicines called antimetabolites which affect cell growth, including the growth of cancer cells.

Methotrexate can be used to treat severe cases of psoriasis (a skin disease) and rheumatoid arthritis (a disease of the joints). It is usually used for patients who have tried other treatments but their illness has not improved. It helps patients with psoriasis by killing the cells in the skin which are growing too quickly. It is these fast growing cells which cause the raised patches of skin in psoriasis.

In the treatment of rheumatoid arthritis, methotrexate is thought to stop or reduce inflammation in the joints by altering the body’s defence mechanism in the immune system.

Methotrexate can also be used to treat several kinds of cancer, in particular:

  • acute leukaemias
  • Non-Hodgkin’s lymphoma
  • soft tissue and bone sarcomas
  • solid tumours like breast, lung, head and neck, bladder, cervical, ovarian and testicular cancer.

Methotrexate can be given alone or in combination with other medicines. It is usually used in much higher doses when it is used to treat cancer and it will often be given as an injection rather than tablets.

You should consult your doctor if you are unsure why you have been given Methotrexate Tablets IP.

  1. What you need to know before you take methotrexate tablets IP

Do not take Methotrexate Tablets IP

  • if you know that you are allergic to methotrexate or any of the other ingredients of this medicine (listed in section 6)
  • if you are pregnant, breast-feeding (see section : Pregnancy, breast-feeding and fertility)
  • if you suffer from a problem of excessive drinking (alcoholism)
  • if you have severe liver problems, including fibrosis, alcoholic liver disease and recent or active hepatitis (inflammation of the liver)
  • if you have severe kidney problems, including conditions requiring kidney dialysis
  • if you have any serious blood disorders including severe anaemia or abnormal numbers of blood cells such as low white cells (leucopenia) or low small blood cell numbers (platelets) causing (thrombocytopenia)
  • if you have a medical condition or are receiving medication which lowers your resistance to infection
  • if you are taking antibiotics which prevent the production of folic acid (vitamin B9) such as cotrimoxazole, which are used to treat bacterial infections
  • if you have symptoms which may suggest an active infectious disease (e.g. fever, chills, achiness).

Even though some of the above may be obvious, it is important that your doctor is aware if any of them apply to you.

Warnings and precautions

Important warning about the dose of Methotrexate Tablets IP:

Take Methotrexate Tablets IP only once a week for the treatment of rheumatic or skin diseases (RA, JIA and psoriasis or psoriatic arthritis).

Taking too much of Methotrexate Tablets IP may be fatal.

Please read section 3 of this leaflet very carefully.

If you have any questions, please talk to your doctor or pharmacist before you take this medicine.

Talk to your doctor, pharmacist or nurse before taking Methotrexate Tablets IP if you:

  • have any mild or moderate liver or kidney problems or blood disorders including anaemia
  • have gastro-intestinal (digestive) problems like stomach ulcers or suffer from inflammation and ulceration of the gut
  • have or have ever suffered from mental illness
  • have severe mouth ulcers
  • have diarrhea
  • have any symptoms or signs of infection
  • have excess fluid between the lungs and chest wall (pleural effusion) causing breathlessness or in the abdomen causing swelling of the stomach (ascites). These may affect the levels of methotrexate in your blood
  • are receiving or intend to receive any vaccine, as methotrexate can reduce their effect
  • have diabetes mellitus
  • are an elderly patient or a very young child
  • develop a persistent cough or develop shortness of breath as it may be associated with serious lung disease
  • have received or you are receiving radiotherapy or ultraviolet (UV) radiation concurrently
  • acute bleeding from the lungs in patients with underlying rheumatologic disease has been reported with methotrexate. If you experience symptoms of spitting or coughing up blood you should contact your doctor immediately.

Methotrexate temporarily affects sperm and egg production. Methotrexate can cause miscarriage and severe birth defects. You and your partner should avoid having a baby if you are being given methotrexate at the time and for at least 6 months after the end of your treatment with methotrexate. See also section “Pregnancy, breast-feeding and fertility”.

Regular check–ups

Whilst being treated with this medicine your doctor will want to monitor your progress on a weekly basis until your therapy is stable. Thereafter, you will be monitored every 2 to 3 months, whilst taking the medicine. These checks may include taking blood and urine samples to check your blood cells and to make sure that your liver and kidneys are working properly. It is important that you do not miss any blood tests.

There may also be a chest x-ray and a physical examination to check for swelling of your lymph nodes (glands in your neck, armpits and groin). Any unusual swellings should also be reported to your doctor.

Other medicines and Methotrexate Tablets IP:

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription. The effects of these medicines may change, especially if you are taking:

  • NSAIDs (non-steroidal anti-inflammatory drugs) e.g. ibuprofen, indomethacin, azopropazone or aspirin (for relief of pain or inflammation) including any preparations of these bought without a prescription. Taking these products together with Methotrexate Tablets IP can increase its toxic effects
  • diuretics (e.g. loop diuretics like furosemide, hydrochlorothiazide or triamterene – water pills)
  • phenytoin, carbamazepine and valproate (for seizures)
  • antibiotics (used to treat bacterial infections) including penicillin, sulphonamides, trimethoprim/sulfamethoxazole (as cotrimoxazole), neomycin, ciprofloxacin, doxycycline, tetracyclines, chloramphenicol

Methotrexate Tablets IP with food and drink

You should not drink alcohol whilst you are taking this medicine.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.


Do not use Methotrexate Tablets IP during pregnancy except if your doctor has prescribed it for oncology treatment. Methotrexate can cause birth defects, harm the unborn child or cause miscarriage. It is associated with malformations of the skull, face, heart and blood vessels, brain, and limbs. It is therefore very important that methotrexate is not given to pregnant women or to women who are planning to become pregnant unless used for oncology treatment.

For non-oncological indications, in women of child-bearing age the possibility of a pregnancy must be ruled out, e.g. by pregnancy tests, before treatment is started. Do not use Methotrexate Tablets IP if you are trying to become pregnant. You must avoid becoming pregnant during treatment with methotrexate and for at least 6 months after the end of treatment. Therefore, you must ensure that you are taking effective contraception for the whole of this period (see also section “Warnings and precautions”).

If you become pregnant during treatment or suspect you might be pregnant, speak to your doctor as soon as possible. If you do become pregnant during treatment, you should be offered advice regarding the risk of harmful effects on the child through treatment.

If you want to become pregnant, you should speak with your doctor, who may refer you for specialist advice before the planned start of treatment.


Methotrexate Tablets IP should not be used during breast-feeding. Methotrexate passes into breast milk. Breast-feeding should be stopped prior to and during treatment with Methotrexate Tablets IP.

Male fertility

The available evidence does not indicate an increased risk of malformations or miscarriage if the father takes methotrexate less than 30 mg/week. However, a risk cannot be completely excluded and there is no information regarding higher methotrexate doses. Methotrexate can have a genotoxic effect. This means that the medicine can cause genetic mutations. Methotrexate can affect the production of sperm, which is associated with the possibility of birth defects.

You should avoid fathering a child or to donate semen during treatment with methotrexate and for at least 6 months after the end of treatment. As treatment with methotrexate at higher doses commonly used in cancer treatment can cause infertility and genetic mutations, it may be advisable for male patients treated with methotrexate doses higher than 30 mg/week to consider sperm preservation before the beginning of treatment (see also section “Warnings and precautions”).

It may also affect women’s periods; they may become less frequent or stop completely.

Driving and using machines

Methotrexate Tablets IP may make you feel drowsy, dizzy or may give you blurred vision. You should not drive or use machines when you first start to take this medicine until you are certain that you are not getting these side effects. If in any doubt, speak to your doctor before you drive or use machines.

Methotrexate Tablets IP contains lactose and sodium

These tablets contain lactose (a type of sugar). If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

This medicine contains less than 1 mmol sodium (23 mg) per dosage unit, that is to say essentially ‘sodium-free’.


Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Do not take more tablets than your doctor has told you to. It will not make you better any faster and it may harm you.

Dosage for treatment of cancer:

Adults, the Elderly and Children

Your doctor will want to monitor your progress, usually every 2-3 months, whilst you are receiving Methotrexate Tablets IP.

Before, during and after your treatment you may have tests, such as a chest X-ray, physical examination and blood tests to check that your liver and kidneys are working properly.

Pregnancy-related tumours

The recommended dose for Pregnancy related tumours is 0.25-1 mg /kg up to a maximum of 60 mg every 48 hours for four doses with Calcium Leucovorin rescue. Your doctor will tell you to repeat this treatment at seven-day intervals. Not less than four courses of treatment are usually necessary.

Lymphoma: The recommended dose is 3-30 mg/kg of methotrexate given by injection along with Calcium Leucovorin with the higher doses. It may also be given alongside other medicines as part of chemotherapy.

Burkitt’s lymphoma: The recommended dose is 15 mg/m2 daily orally for five days. It may also be given alongside other medicines as part of chemotherapy.

Breast cancer

The recommended dose is 10-60 mg/m2 of methotrexate are usually given by injection by your doctor or nurse alongside other medicines as part of chemotherapy.

Bone cancer

The recommended dose is 20-300 mg/kg (approximately 600-9,000 mg/m2) of methotrexate with Calcium Leucovorin rescue are used in the treatment of bone cancer. It may also be given alongside other medicines as part of chemotherapy.

Lung cancer

The recommended dose is 20-100 mg/m2 of methotrexate have been included in cyclical combination regimes for the treatment of advanced tumours.

Head and neck cancer

The recommended dose is 240-1,080 mg/m2 methotrexate with calcium Leucovorin are used in the treatment of head and neck cancers.

Bladder cancer

The recommended dose is up to 100 mg are usually given by injection by your doctor or nurse.

The recommended dose is methotrexate 15 mg/m2, parenterally or orally once weekly, in combination with other drugs appears to be the treatment of choice for maintenance of drug-induced remissions.

Meningeal leukaemia

The recommended dose is up to 15 mg, intrathecally, at weekly intervals, until the CSF appears normal (usually two to three weeks), have been found useful for the treatment of meningeal leukaemia.

Dose in psoriasis:

Take Methotrexate 2.5 mg Tablet only once a week.


USUAL DOSE: between 10 and 25 mg by mouth (4 to 10 tablets) taken once a week on the same day each week. This should be adjusted according to your response to treatment and side effects.

Elderly: No dosage adjustment required.

Children: Not recommended for use in children.

Dose in rheumatoid arthritis:

Take Methotrexate 2.5 mg Tablet only once a week.

USUAL DOSE: between 7.5 and 20 mg (3 to 8 tablets) taken once a week on the same day each week.

These doses may alter as your condition changes.

Do not miss your appointments as these are necessary to ensure that Methotrexate Tablets IP are used safely.

Your doctor may give you additional medication to help make sure that methotrexate does not collect in the kidneys.

Blood monitoring should be done for all patients treated with methotrexate. Close monitoring of the blood levels should be done including the complete blood counts, urine tests and in some cases blood methotrexate monitoring along with liver and kidney function tests to detect any problems.

The score line is only there to help you break the tablet if you have difficulty swallowing it whole.

If you take more Methotrexate Tablets IP than you should

If you have taken an overdose of methotrexate or more tablets than the doctor has told you to, you should get medical help immediately either by calling your doctor or by going to the nearest hospital casualty department. Always take the labelled medicine container with you, whether there are any Methotrexate Tablets IP left or not.

Inappropriate intake resulting in overdose can sometimes lead to death.

If you forget to take Methotrexate Tablets IP

If you forget to take a dose, take it as soon as you remember if this is within two days. However, if you have missed a dose by more than two days, please contact your doctor for advice. Do not take a double dose to make up for a forgotten dose. If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.

  1. Possible side effects

Like all medicines, this medicine may cause side effects, although not everybody gets them.

Tell your doctor immediately if you experience any of the following symptoms after taking this medicine. Although they are very rare, these symptoms can be serious.

All medicines can cause allergic reactions although serious allergic reactions are rare. Any sudden wheeziness, difficulty in breathing, swelling of the eyelids, face or lips, rash or itching (especially affecting your whole body), spitting or coughing blood* should be reported to a doctor immediately.
