Why is LEFRA (Leflunomide, Arava) prescribed?

Most important fact about LEFRA (Leflunomide, Arava)
You MUST NOT take LEFRA (Leflunomide, Arava) if you are pregnant; it can harm the developing
baby. If you are still in your childbearing years, your doctor will
want to see negative results from a pregnancy test before starting
you on LEFRA (Leflunomide, Arava). You'll also need to use reliable contraceptive measures
as long as you take the drug.
If you become pregnant while taking LEFRA (Leflunomide, Arava), your doctor will stop the
drug immediately and prescribe a regimen of cholestyramine (Questran)
in 8-gram doses 3 times a day for 11 days. Questran helps to clear
LEFRA (Leflunomide, Arava) from the bloodstream, possibly preventing harm to the unborn
child.

Special warnings about LEFRA (Leflunomide, Arava)
LEFRA (Leflunomide, Arava) is potentially damaging to the liver. Your doctor will test
your liver function before starting LEFRA (Leflunomide, Arava) therapy. If you have significant
liver disease, including hepatitis, you'll be unable to take LEFRA (Leflunomide, Arava).
If you develop liver problems while taking the drug, your dose will
have to be reduced or eliminated.
Theoretically, LEFRA (Leflunomide, Arava) may interfere with your body's ability to fight
off infection. The drug is therefore not recommended for people with
cancer, bone marrow problems, severe infections, AIDS, or any other
immune system problems. You should also avoid immunization with live
vaccines while taking LEFRA (Leflunomide, Arava).
Since there is a possibility that LEFRA (Leflunomide, Arava) could damage your liver or
cause blood problems (such as a loss of white blood cells used to fight
infection or a loss of cells that help your blood clot), it is essential
that your doctor conducts a monthly blood test for the first 6 months
of therapy, then every 6 to 8 weeks thereafter. If you are taking LEFRA (Leflunomide, Arava)
and the cancer drug methotrexate together you may be even more susceptible
to these problems. Your doctor will need to test your blood every month.
Notify your doctor promptly if any signs of a blood problem appear.
Warnings include easy bruising, frequent infections, unusual fatigue,
and paleness.
LEFRA (Leflunomide, Arava) has been known to cause rare but serious skin reactions. If
you develop a skin rash or eruption, stop taking LEFRA (Leflunomide, Arava) and contact
your doctor. LEFRA (Leflunomide, Arava) can also reduce your blood cell count.
Your doctor will prescribe the drug cautiously if you have kidney
problems, since poor kidney function can increase the amount of LEFRA (Leflunomide, Arava)
in your system.
LEFRA (Leflunomide, Arava) does not appear to cause fetal harm when taken by the father
prior to conception. Nevertheless, if you plan to father a child, your
doctor will instruct you to stop taking LEFRA (Leflunomide, Arava) and will prescribe a
regimen of cholestyramine to clear LEFRA (Leflunomide, Arava) from your system.
Possible food and drug interactions when taking LEFRA (Leflunomide, Arava)

to check with your doctor before combining LEFRA (Leflunomide, Arava) with the following:
