What is in this leaflet
This leaflet answers some common questions about ATARIS.
It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking ATARIS 10 or ATARIS 20 against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine.
You may need to read it again.
What ATARIS is used for
ATARIS is a type of medicine used to treat rheumatoid or psoriatic arthritis. ATARIS 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.
ATARIS 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, however, may have prescribed ATARIS 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.
