What Arabloc is used for
Arabloc is a type of medicine 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.
Your doctor, overnight evista however, may have prescribed Arabloc for another purpose.
Ask your doctor if you have any questions about why it has been prescribed for you.
This medicine is only available with a doctor’s prescription.
