Generic Name: etanercept (ee-TAN-er-sept)
Brand Name: Enbrel Prefilled Syringes
Patients who use etanercept have an increased risk of developing serious and sometimes fatal infections (eg, bacterial, viral, fungal infections; tuberculosis [TB]). Most patients who developed these infections were taking medicines that weakened their immune systems (eg, corticosteroids, methotrexate).
TB may be caused by a new infection or by reactivation of a previous infection. Your doctor will test you for TB and evaluate your risk of developing it. This will occur before, during, and after treatment with etanercept. If you have TB, you should begin to treat it before you begin treatment with etanercept. Tell your doctor if you have a history of persistent or recurring infections.
Contact your doctor immediately if you develop signs of TB or any other type of infection (eg, persistent cough; muscle weakness; unexplained weight loss; fever, chills, or persistent sore throat; shortness of breath; unusual tiredness; warm, red, or painful skin; sores on your body; increased or painful urination).
Etanercept is a tumor necrosis factor (TNF) blocker. Lymphoma and other types of cancer have been reported in children and teenagers treated with TNF blockers. This has been fatal in some cases. Talk with your doctor for more information.
Etanercept is used for:
Treating moderate to severe forms of ankylosing spondylitis (AS), juvenile arthritis, certain types of skin psoriasis, and rheumatoid and psoriatic arthritis. Etanercept may be used alone or with other medicines. It may also be used for other conditions as determined by your doctor.
Etanercept is a TNF blocker. It works by blocking a protein (TNF-alpha) found in the body that causes inflammation.
Do NOT use etanercept if:
- you are allergic to any ingredient in etanercept, or to latex or rubber
- you have an infection that has spread throughout your entire body (sepsis)
- you have Wegener granulomatosis and are taking a medicine that may weaken the immune system (eg, corticosteroids, methotrexate)
- you are taking cyclophosphamide, abatacept, anakinra, or tocilizumab
Contact your doctor or health care provider right away if any of these apply to you.

Some MEDICINES MAY INTERACT with etanercept. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Corticosteroids (eg, prednisone), costimulation modulators (eg, abatacept), interleukin-1 receptor antagonist (eg, anakinra), methotrexate, or tocilizumab because the risk of serious infections may be increased
