Information on Tablets A-Z
Generic name: Etanercept
Why is this drug prescribed: Enbrel is used to relieve the symptoms and slow the progress of moderate to severe rheumatoid arthritis. It's also prescribed to relieve the symptoms of psoriatic arthritis. It can be added to methotrexate (Rheumatrex) therapy when methotrexate fails to provide adequate relief. Prescribed alone, it is also used for juvenile rheumatoid arthritis when other drugs have failed. Enbrel is the first in a class of drugs designed to block the action of tumor necrosis factor (TNF), a naturally occurring protein responsible for much of the joint inflammation that plagues the victims of rheumatoid arthritis. In clinical trials, Enbrel provided the majority of patients with significant relief.
Most important fact about this drug: TNF plays a significant role in the immune system, so blocking its action can lower your resistance to infection. Serious--and even fatal--infections have been known to occur, especially in people whose immune systems have already been weakened by advancing age, conditions such as heart failure or diabetes, or drugs such as Imuran, Prograf, Cellcept, Neoral, and Sandimmune. Due to the possibility of lowered resistance, children with juvenile rheumatoid arthritis should be brought up to date with all immunizations before starting Enbrel therapy.
How should you take this medication: Enbrel is given by injection under the skin of the thigh, abdomen, or upper arm. Your doctor will instruct you in the proper drug preparation and injection technique and supervise your first injection in the office. You should rotate injection sites and make each new injection at least 1 inch from an older one. Never inject into areas where the skin is tender, bruised, red, or hard. Do not shake Enbrel solution. Avoid handling the needle cover if you have a latex allergy. Never reuse a syringe. Throw it away in a puncture-proof container immediately after using it. --If you miss a dose... Take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and return to your regular schedule. Do not take 2 doses at once. --Storage instructions... Store Enbrel powder in the refrigerator. Do not freeze. Discard after the expiration date stamped on the dose tray. After the powder has been mixed with sterile water, it can be stored under refrigeration for up to 14 days.

Why should this drug not be prescribed: If Enbrel gives you an allergic reaction, you will not be able to continue using it. Do not start taking it during any kind of infection. Think carefully about using this drug if you are prone to repeated infections or have a condition that encourages infections, such as diabetes. Be cautious, too, if you have a disease of the nervous system such as multiple sclerosis or a seizure disorder; such problems have been known to develop or get worse during Enbrel therapy. Enbrel should also be used with caution if you are prone to blood disorders, since they have occasionally appeared during treatment with Enbrel.
Special warnings about this medication: If you develop an infection, stop taking Enbrel and call your doctor immediately. Children exposed to chickenpox during Enbrel therapy may have to temporarily discontinue the drug and get preventive treatments. Enbrel may worsen congestive heart failure. If you have this condition, make sure the doctor knows about it; Enbrel should be used with caution. Enbrel has been known to trigger a condition similar to lupus. If you develop warning signs such as raised patches of red skin, see the doctor immediately. Enbrel therapy may have to be stopped. Also check with your doctor immediately if you develop warning signs of a blood disorder, including such symptoms as persistent fever, bruising, bleeding, or paleness.
