How it works

Leflunomide belongs to a group of medicines called disease-modifying anti-rheumatic drugs (DMARDs), which 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.
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.
There is no evidence that this medicine is addictive.

Use in children

There is not enough information to recommend the use of this medicine in children under 18 years of age.
