Leflunomide is used to treat active rheumatoid arthritis in adults to reduce signs and symptoms, slow down damage to joints, and improve physical function. It works by suppressing your immune system, since rheumatoid arthritis is caused by damage from an overactive immune system.Leflunomide is usually taken once a day. Take Leflunomide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Common Side Effects Include:
- Nausea, diarrhea, flu-like symptoms, mild dizziness, and headache may occur. If these effects persist or worsen, notify your doctor promptly.
Tell your doctor immediately if any of the following unlikely but serious side effects occur:
- hair loss, chest pain, back pain, mouth sores, muscle cramping, numbness/tingling sensations.
- Leflunomide has rarely caused serious (possibly fatal) infections and blood disorders due to suppressing the bone marrow and immune system.
Tell your doctor immediately if signs of infection (such as fever), extreme weakness/fatigue or easy bruising/bleeding develop. Leflunomide may need to be stopped. The elimination procedure using cholestyramine or charcoal may be required. Consult your doctor for more details.
