Leflunomide comes in tablet form and is typically taken once a day. It belongs to a class of drugs called disease-modifying antirheumatic drugs (DMARDs).
This prescription drug works by blocking the body's ability to make molecules called pyrimidines. Certain immune cells in the body that cause inflammation need these molecules to reproduce. By inhibiting production of these molecules, leflunomide reduces inflammation and prevents further joint damage.
Most people tolerate this medication well, but side effects can occur and may include hair loss,
headaches, and a rash.
