What is leflunomide used for?
Leflunomide is a prescription medicine used to treat autoimmune inflammatory diseases, most commonly rheumatoid arthritis and psoriatic arthritis. It helps reduce joint inflammation and slow disease progression in these conditions.
When do doctors prescribe it for rheumatoid arthritis vs. psoriatic arthritis?
For rheumatoid arthritis, leflunomide is used to control symptoms (like pain and swelling) and help prevent ongoing joint damage.
For psoriatic arthritis, it can be used to treat inflammatory arthritis related to psoriasis.
How does leflunomide work?
Leflunomide reduces the activity of the immune system, which helps lower inflammation and autoimmune joint damage. It is considered a disease-modifying antirheumatic drug (DMARD).
Who usually isn’t able to take it?
Because leflunomide can harm an unborn baby, it is generally not used during pregnancy, and effective contraception is required for people who can become pregnant and for their partners in situations where pregnancy is possible (as directed by a clinician). It also requires caution in people with certain liver conditions or significant liver risk.
What should patients know about starting and monitoring?
Patients typically need regular blood tests, especially to monitor liver function and blood counts, since leflunomide can affect both.
What side effects do people ask about most?
Common concerns include diarrhea, nausea, headache, and changes in liver tests. More serious but less common problems can include significant liver injury, lung-related side effects, and low blood counts.
If you tell me whether you mean leflunomide for rheumatoid arthritis, psoriatic arthritis, or another condition (and the country you’re in), I can tailor the answer to the exact indication and typical dosing/monitoring approach.
