How it works
Leflunomide belongs to a group of medicines called disease-modifying anti-rheumatic drugs (DMARDs), which act to decrease joint damage and disability due to rheumatoid arthritis.
In rheumatoid arthritis, leflunomide works by reducing the activity of the immune system, which helps to reduce inflammation, swelling and pain in affected joints. It also helps to reduce damage to those joints.
