What this medicine is used for

Leflunomide is used to treat rheumatoid arthritis and psoriatic arthritis.
It belongs to a group of medicines called disease-modifying anti-rheumatic drugs (DMARDs).

How it works

Leflunomide works by selectively interfering with the ability of white blood cells called lymphocytes to produce the disease response that ultimately leads to pain, inflammation and joint damage.
Leflunomide helps to slow down the process of joint damage and to relieve the symptoms of the disease, such as joint tenderness and swelling, pain and morning stiffness.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor’s prescription.
This medicine is not addictive.
There is not enough information to recommend the use of this medicine in children under 18 years of age.
