METHOTREXATE-ORAL (cont.)
USES: Methotrexate is used to treat certain types of cancer or to control severe psoriasis or rheumatoid arthritis. This medication works by interfering with cell growth and by suppressing the immune system. Early treatment of rheumatoid arthritis with more aggressive therapy such as methotrexate helps to reduce further joint damage and to preserve joint function.
OTHER USES: This medication has also been used to treat other disorders such as lupus and psoriatic arthritis.
HOW TO USE: This is a potent medication. The dose and how often you take this drug is based on your medical condition and response to therapy.

Take it by mouth exactly as directed. For managing psoriasis or rheumatoid arthritis, take this medication exactly as directed, usually once a week.
