Orencia (abatacept) is a 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 a prescription medicine used to treat symptoms of rheumatoid arthritis, and to prevent joint damage caused by these conditions. This medicine is for adults and children at least 2 years old.
Orencia is also used to treat active psoriatic arthritis in adults.
Orencia is not a cure for any autoimmune disorder and will only treat the symptoms of your condition.
