Full Consumer Medicine Information (CMI)
This leaflet provides important information about using Arabloc. You should also speak to your doctor or pharmacist if you would like further information
or if you have any concerns or questions about using Arabloc.
Where to find information in this leaflet:
1. Why am I using Arabloc?
Arabloc contains the active ingredient leflunomide. Arabloc is an immunosuppressive medicine, which means that it works by reducing the
activity of the immune system.
Arabloc is used to treat rheumatoid or psoriatic arthritis.
Arabloc 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.
Arabloc 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.
2. What should I know before I use Arabloc?
