Leflunomide

Leflunomide is a prescription medicine used to reduce inflammation by slowing down immune system activity. It belongs to a class called disease-modifying antirheumatic drugs (DMARDs), so it does not work like a typical pain reliever.

It is mainly used for rheumatoid arthritis and may be prescribed to help control joint pain, swelling, and stiffness. Important safety points include liver monitoring, blood tests, and avoiding use during pregnancy because it can cause serious harm to an unborn baby.
