Orencia Side Effects

Orencia (abatacept) is a man-made protein that prevents your body’s immune system from attacking healthy tissues such as joints. The immune system helps your body fight infections. In people with autoimmune disorders, the immune system mistakes the body’s own cells for invaders and attacks them.

Orencia is used to treat the symptoms of rheumatoid arthritis, and to prevent joint damage caused by these conditions. Orencia is also used to treat arthritis in children who are at least 6 years old.

Orencia is not a cure for any autoimmune disorder and will only treat the symptoms of your condition.

You should not use Orencia if you are allergic to abatacept, or if you are also using anakinra (Kineret), etanercept (Enbrel), adalimumab (Humira), certolizumab (Cimzia), golimumab (Simponi), infliximab (Remicade), natalizumab (Tysabri), rituximab (Rituxan), or tocilizumab (Actemra).

Before using Orencia, tell your doctor if you have ever had tuberculosis, if anyone in your household has tuberculosis, or if you have recently traveled to an area where tuberculosis is common.
