What is Enbrel?

Enbrel is a tumor necrosis factor (TNF) blocker. It works by decreasing TNF, a protein produced by the immune system to helps the body fight infections. In people with autoimmune disorders, the immune system produces too much TNF and mistakenly attacks healthy cells.

Enbrel is used to treat rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis, and to prevent joint damage caused by these conditions.

Enbrel is also used to treat polyarticular juvenile idiopathic arthritis in children who are at least 2 years old.

Enbrel is also used to treat plaque psoriasis in adults and children who are at least 4 years old.

Enbrel is sometimes used with another medicine called methotrexate when treating rheumatoid arthritis and psoriatic arthritis.

Warnings

Using Enbrel may increase your risk of developing certain types of cancer, including a rare type of lymphoma. Ask your doctor about your specific risk. This has occurred mainly in teenagers and young adults using Enbrel or similar medicines to treat Crohn's disease or ulcerative colitis. Call your doctor at once if you have any of the following symptoms: fever, night sweats, itching, loss of appetite, weight loss, tiredness, feeling full after eating only a small amount, pain in your upper stomach that may spread to your shoulder, nausea, easy bruising or bleeding, pale skin, feeling light-headed or short of breath, rapid heart rate, dark urine, clay-colored stools, or jaundice (yellowing of the skin or eyes).

Enbrel can weaken your immune system. Serious and sometimes fatal infections may occur. Call your doctor right away if you have signs of infection such as: fever, chills, cough, sweating, body aches, skin sores or redness, diarrhea, burning when you urinate, or feeling very tired or short of breath.

Before taking this medicine

Children should be current on all childhood immunizations before starting treatment with Enbrel.

Using Enbrel may increase your risk of developing certain types of cancer, including a fast-growing lymphoma that can be fatal. This rare lymphoma has occurred in male teenagers and young men using a combination of immunosuppressant medicines to treat Crohn's disease or ulcerative colitis. However, people with autoimmune disorders (including rheumatoid arthritis, Crohn's disease, ankylosing spondylitis, and psoriasis) may have a higher risk of lymphoma. Talk to your doctor about your individual risk.

Etanercept can pass into breast milk and may harm a nursing baby. You should not breast-feed while using this medicine.

How should I use Enbrel?

Before you start treatment with Enbrel, your doctor may perform tests to make sure you do not have an infection.

Enbrel is injected under the skin. A healthcare provider may teach you how to properly use the medication by yourself. Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.

Do not shake this medicine. Prepare an injection only when you are ready to give it. Do not use if the medicine looks cloudy, has changed colors, or has particles in it. Call your pharmacist for new medicine.

You may need to mix Enbrel with a liquid (diluent). When using injections by yourself, be sure you understand how to properly mix and store the medicine.

Etanercept doses are based on weight in children. Your child's dose needs may change if the child gains or loses weight.

Enbrel affects your immune system. You may get infections more easily, even serious or fatal infections. Your doctor will need to examine you on a regular basis.

If you've ever had hepatitis B, using Enbrel can cause this virus to become active or get worse. You may need frequent liver function tests while using this medicine and for several months after you stop.

Carefully follow all storage instructions provided with your medicine.

Each cartridge, injection pen, or prefilled syringe is for one use only. Throw it away after one use, even if there is still medicine left inside.
