Methotrexate therapy should be considered in patients with active disease with risk factors for poor prognosis (see above). Rheumatology consultation is suggested to help with the decision to start methotrexate, to guide dose titration, and to establish a monitoring schedule. Mechanism: Although the immunosuppressive and cytotoxic effects of methotrexate are due to the inhibition of dihydrofolate reductase, the anti-inflammatory effects in rheumatoid arthritis appear to be unrelated to this mechanism of action and remain unclear. Dosage: Methotrexate (available as a 2. 5mg tablet) is prescribed in an initial dosage of 7. 5mg once weekly. Rarely, some patients prefer to use 2. 5mg every 12 hours for three doses to reduce GI side effects. If no effect is noted in 4 to 6 weeks, then the dose can be increased to 15mg once weekly. The dose can be increased to 10mg or 12. 5mg weekly in the elderly or in partial responders. The maximal dose is 25mg weekly. Some patients who experience intolerable GI side effects can be changed to self-administered IM injections (methotrexate is available as 25mg/ml solution). Patients should be carefully selected not to have renal insufficiency, acute or chronic liver disease, alcohol abuse, leukopenia, thrombocytopenia, or untreated folate deficiency. Obesity, diabetes and history of hepatitis B or C are factors that have been suggested but not confirmed to increase methotrexate hepatotoxicity.
