Action plan: Low-dose methotrexate ​for rheumatoid arthritis and psoriatic arthritis

Rheumatoid arthritis (RA) and psoriatic arthritis (PsA) are long-term conditions where the body’s immune system mistakenly attacks healthy tissues such as the joints and skin. This causes inflammation, leading to symptoms such as joint pain and swelling. Use this action plan to discuss methotrexate with your rheumatologist and plan the best way to take your medicine.
