Methotrexate is a chemotherapy drug used to treat myositis. It comes in an oral pill form as well as a subcutaneous injection. It may take up to 12 weeks (or longer for some) for Methotrexate to take full effect. This drug works by suppressing the immune system, thereby preventing it from being self-reactive.
Methotrexate has many side effects including, drowsiness, dizziness, headache, swollen gums and hair loss. Side effects can be mediated by taking folic acid except on the day the methotrexate is taken.Tags: methotrexate myositis treatment
