🔔 Why is this medication prescribed?
Leflunomide is used alone or in combination with other medications to treat rheumatoid arthritis (a condition in which the body attacks its own joints, causing pain, swelling, and loss of function). Leflunomide is in a class of medications called disease-modifying antirheumatic drugs (DMARDs). It works by decreasing inflammation and slowing the progress of the condition, which can help improve the physical activity of people with rheumatoid arthritis.
🔔 How should this medicine be used?
Leflunomide comes as a tablet to take by mouth. It is usually taken once a day. Your doctor may tell you to take a larger dose of leflunomide for the first 3 days of treatment. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take leflunomide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Long wait times are often cited as a downfall of universal healthcare systems, but wait times in America have reached a new high, too. The average time to make a physician appointment as a new patient in 15 major U.S. cities is now 24 days, up 30% in just 3 years (2014 to 2018) according to physician recruiting firm Merritt Hawkins.
Your doctor may need to decrease your dose or stop treatment if you experience certain severe side effects. Be sure to tell your doctor how you are feeling during your treatment.
Leflunomide may help control the symptoms of your rheumatoid arthritis but does not cure it. Continue to take leflunomide even if you feel well. Do not stop taking leflunomide without talking to your doctor.
