Methotrexate (MTX) is an immunosuppressive drug that is FDA-approved for treating psoriasis. It is also used widely and successfully for treating psoriatic arthritis and rheumatoid arthritis.
Methotrexate can be effective at relieving the symptoms associated with psoriatic arthritis, and it may help prevent joint destruction.
Methotrexate usually is well tolerated in low doses. However, it potentially has a number of side effects and the long-term potential of damaging the liver. With careful management and dosage, the drug can be used safely for years by certain individuals. A person taking methotrexate should follow a doctor's instructions carefully.
