Enbrel prefilled syringes

Pronunciation

Generic Name: etanercept (ee-TAN-er-sept)
Brand Name: Enbrel

Patients who use Enbrel prefilled syringes 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 Enbrel prefilled syringes. If you have TB, you should begin to treat it before you begin treatment with Enbrel prefilled syringes. 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).

Enbrel prefilled syringes are 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.
