Etanercept works by decreasing a certain protein produced by the immune system. The immune
system helps the body fight infections. In people with autoimmune disorders, the immune system
mistakes the body's own cells for invaders and attacks them.
Etanercept is used to treat the symptoms of rheumatoid arthritis, psoriatic arthritis, or ankylosing
spondylitis, and to prevent joint damage caused by these conditions. It is also used to treat plaque
psoriasis in adults and polyarticular juvenile idiopathic arthritis in children who are at least 2 years old.
Etanercept is
not a cure
for any autoimmune disorder and will only treat the
symptoms of your condition.
Etanercept may also be used for other purposes not listed in this medication guide.
