Methotrexate has been widely used for many years in the treatment of a variety of diseases. Low-dose oral methotrexate therapy has gained wide acceptance for its use in rheumatoid arthritis because of its efficacy and tolerability. The toxicity of methotrexate is the main reason for cessation of treatment. Gastrointestinal complications are the most common adverse effects of low-dose oral methotrexate therapy, followed by stomatitis, hepatotoxicity, skin rash, hair loss, pulmonary and haematological toxicity, although pancytopenia is a rare adverse effect of low-dose oral methotrexate therapy. The most important risk factor for methotrexate toxicity is impaired renal function.
