What is the most important information I should know about leflunomide (Arava)?

Leflunomide can harm an unborn baby or cause birth defects. Do not use leflunomide if you are pregnant. Your doctor may want you to have a pregnancy test to make sure you are not pregnant before you start taking leflunomide.

Stop taking leflunomide and tell your doctor right away if you become pregnant during treatment. You will need to receive medications to help your body eliminate the drug quickly and reduce the risk of harm to your unborn baby.

Use effective birth control while you are taking leflunomide, whether you are a man or a woman. After your treatment ends, continue using birth control until you have received the drug elimination medications.

Before taking leflunomide, tell your doctor if you have a history of liver disease or hepatitis, kidney disease, any type of infection, a history of tuberculosis, a blood cell disorder such as anemia or low platelets, a bone marrow disorder, or if you are using any drugs that weaken your immune system (such as cancer medicine or steroids).

Leflunomide can make it easier for you to get sick. Avoid being near people who have colds, the flu, or other contagious illnesses. Contact your doctor at once if you develop signs of infection.

Do not receive a "live" vaccine while you are being treated with leflunomide, and avoid coming into contact with anyone who has recently received a live vaccine. There is a chance that the virus could be passed on to you.

After you stop taking leflunomide, you may need to be treated with other medications to help your body eliminate leflunomide quickly. Without receiving this drug elimination procedure, leflunomide could stay in your body for up to 2 years. Follow your doctor's instructions.
