When working with Leflunomide, an oral disease‑modifying antirheumatic drug (DMARD) that blocks pyrimidine synthesis to calm joint inflammation. Also known as Arava, it is prescribed when patients need a long‑term strategy to slow joint damage and relieve pain.
For most people, the main reason to start leflunomide is to manage rheumatoid arthritis, an autoimmune condition that attacks the lining of joints, causing swelling, stiffness, and eventual deformity. This disease falls under the umbrella of DMARDs, a class of medications designed to modify the underlying immune response rather than just mask symptoms. By interfering with the enzyme dihydroorotate dehydrogenase, leflunomide reduces the proliferation of activated lymphocytes, which are the culprits behind the joint attack. In plain terms, it tells the immune system to chill out, giving joints a chance to heal.
Because leflunomide is an immunosuppressant, any drug that lowers the activity of your immune system, doctors keep a close eye on liver enzymes and blood counts. A typical starting dose is 20 mg once daily, taken with food to improve absorption. After a few weeks, the dose may be adjusted based on how well symptoms improve and how the lab results look. If a patient needs to stop the drug quickly, a short “wash‑out” period with cholestyramine can speed up clearance and reduce the risk of lingering side effects.
Side effects often surface early: mild diarrhea, rash, or a temporary rise in blood pressure are common. More serious concerns include liver toxicity, severe infections, and rare blood disorders. That’s why clinicians compare leflunomide to other DMARDs like methotrexate, a folate‑antagonist commonly used for the same condition and azathioprine, another immunosuppressive agent that interferes with DNA synthesis. While methotrexate is often first‑line because of its long track record, leflunomide can be a better fit for patients who can’t tolerate methotrexate’s weekly dosing or who have specific liver concerns. Azathioprine, on the other hand, is usually reserved for organ‑transplant patients or severe autoimmune cases, so its interaction profile with leflunomide matters if they’re ever combined.
Before you or someone you know starts leflunomide, ask the doctor about baseline liver tests, pregnancy plans, and any other meds – especially blood thinners or other immunosuppressants. Keep an eye on any new bruising, yellowing of the skin, or persistent cough, and report them right away. Regular follow‑up appointments usually mean a blood draw every 4–8 weeks during the first few months, then every few months once stability is confirmed. If side effects become intolerable, dose reduction or switching to another DMARD is a standard option.
All that said, leflunomide offers a convenient once‑daily pill that can keep rheumatoid arthritis from raging unchecked.
