Leflunomide

Leflunomide is an immunosuppressive disease-modifying antirheumatic drug. It is a pyrimidine synthesis inhibitor. It is used to treat rheumatoid arthritis. It functions by reducing joint pain and swelling.

Certain side-effects that you may experience on using Leflunomide are dizziness, nausea, diarrhoea, hair loss, headache, respiratory tract infections, cough, difficulty breathing, stomatitis, fatigue, itchiness and pharyngitis. Should your allergic reactions continue or worsen over time, immediately contact your health care provider.

Before using Leflunomide have a word with your doctor and inform him/her if: you are allergic to any medication, food, substance or any ingredient contained within Leflunomide, you are pregnant, or are planning to become pregnant or are nursing a baby, you have a weak immune system, you have liver, lung or kidney problems and if you are taking any prescription or non-prescription drugs.

The dosage should be ideally prescribed by your doctor. This medication comes in a tablet form. Usually the adult dose for Leflunomide is about 20 mg (maintenance dose) to be taken through the mouth once for over a period of 3 days.

If diabetic, monitor blood sugars closely; this medication may alter glucose levels. There is no human experience with overdosage. Leflunomide is not dialyzable. Cholestyramine and/or activated charcoal enhance elimination of leflunomide's active metabolite (MI).

In cases of significant overdose or toxicity, cholestyramine 8 g every 8 hours for 1-3 days may be administered to enhance elimination. Plasma levels are reduced by approximately 40% in 24 hours and 49% to 65% after 48 hours of cholestyramine dosing.

Take as directed; do not increase dose without consulting prescriber. Maintain adequate hydration (2-3 L/day of fluids unless instructed to restrict fluid intake). Store medication away from light.

Leflunomide has been associated with teratogenic and embryolethal effects in animal models at low doses. Leflunomide is contraindicated in pregnant women or women of childbearing potential who are not using reliable contraception.

Pregnancy must be excluded prior to initiating treatment. Following treatment, pregnancy should be avoided until the drug elimination procedure is completed.
