What is Arava?
ARAVA (leflunomide) is a pyrimidine synthesis inhibitor. The chemical name for leflunomide is N-(4´-trifluoromethylphenyl)-5-methylisoxazole-4-carboxamide. It has an empirical formula CHFNO, a molecular weight of 270.2 and the following structural formula:
ARAVA is available for oral administration as tablets containing 10, 20, or 100 mg of active drug. Combined with leflunomide are the following inactive ingredients: colloidal silicon dioxide, crospovidone, hypromellose, lactose monohydrate, magnesium stearate, polyethylene glycol, povidone, starch, talc, titanium dioxide, and yellow ferric oxide (20 mg tablet only).

What should I talk to my health care provider before I take Arava?
How should I use Arava?
ARAVA is indicated for the treatment of adults with active rheumatoid arthritis (RA).
The recommended dosage of ARAVA is 20 mg once daily. Treatment may be initiated with or without a loading dose, depending upon the patient's risk of ARAVA-associated hepatotoxicity and ARAVA-associated myelosuppression. The loading dosage provides steady-state concentrations more rapidly.
The maximum recommended daily dosage is 20 mg once per day. Consider dosage reduction to 10 mg once daily for patients who are not able to tolerate 20 mg daily (i.e., for patients who experience any adverse events listed in Table 1).
Monitor patients carefully after dosage reduction and after stopping therapy with ARAVA, since the active metabolite of leflunomide, teriflunomide, is slowly eliminated from the plasma . After stopping ARAVA treatment, an accelerated drug elimination procedure is recommended to reduce the plasma concentrations of the active metabolite, teriflunomide . Without use of an accelerated drug elimination procedure, it may take up to 2 years to reach undetectable plasma teriflunomide concentrations after stopping ARAVA .

What might happen if I take too much Arava?
There have been reports of chronic overdose in patients taking ARAVA at daily dose up to five times the recommended daily dose and reports of acute overdose in adults and children. Adverse events were consistent with the safety profile for ARAVA [See ]. The most frequent adverse events observed were diarrhea, abdominal pain, leukopenia, anemia and elevated liver function tests.
In the event of a significant overdose or toxicity, perform an accelerated drug elimination procedure to accelerate elimination [see .
Studies with both hemodialysis and CAPD (chronic ambulatory peritoneal dialysis) indicate that teriflunomide, the primary metabolite of leflunomide, is not dialyzable [See ].

Chemical StructureNo Image found
Leflunomide is an isoxazole immunomodulatory agent that inhibits dihydroorotate dehydrogenase (a mitochondrial enzyme involved in de novo pyrimidine synthesis) and has antiproliferative activity. Several and experimental models have demonstrated an anti-inflammatory effect.
Non-Clinical ToxicologyARAVA is contraindicated in:
Potential drug interactions between oxiconazole nitrate cream and other drugs have not been systematically evaluated.
ARAVA may cause fetal harm when administered to a pregnant woman. Teratogenicity and embryo-lethality occurred in animal reproduction studies with leflunomide at doses lower than the human exposure level
ARAVA is contraindicated for use in pregnant women . Exclude pregnancy before starting treatment with ARAVA in females of reproductive potential . Advise females of reproductive potential to use effective contraception during ARAVA treatment and during an accelerated drug elimination procedure after ARAVA treatment . If a woman becomes pregnant while taking ARAVA, stop treatment with ARAVA, apprise the patient of the potential risk to a fetus, and perform an accelerated drug elimination procedure to achieve non-detectable plasma concentrations of teriflunomide, the active metabolite of leflunomide
Upon discontinuing ARAVA, it is recommended that all females of reproductive potential undergo an accelerated drug elimination procedure. Women receiving ARAVA treatment who wish to become pregnant must discontinue ARAVA and undergo an accelerated drug elimination procedure, which includes verification that plasma concentrations of the active metabolite of leflunomide, teriflunomide, are less than 0.02 mg/L (0.02 mcg/mL). Based on animal data, human plasma concentrations of teriflunomide of less than 0.02 mg/L (0.02 mcg/mL) are expected to have minimal embryo-fetal risk .
