Read the Medication Guide that comes with Enbrel before you start using it and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking with your doctor about your medical condition or treatment. It is important to remain under your doctor's care while using Enbrel.
What is the most important information I should know about Enbrel?
Enbrel may cause serious side effects, including:
- Risk of Infection
- Risk of Cancer
1. Risk of infection
Enbrel can lower the ability of your immune system to fight infections. Some people have serious infections while taking Enbrel. These infections include tuberculosis (TB), and infections caused by viruses, fungi, or bacteria that spread throughout their body. Some people have died from these infections.
- Your doctor should test you for TB before starting Enbrel.
- Your doctor should monitor you closely for symptoms of TB during treatment with Enbrel even if you tested negative for TB.
- Your doctor should check you for symptoms of any type of infection before, during, and after your treatment with Enbrel.
You should not start taking Enbrel if you have any kind of infection unless your doctor says it is okay.
2. Risk of cancer
- There have been cases of unusual cancers in children and teenage patients who started using TNF-blocking agents at less than 18 years of age.
- For children, teenagers, and adults taking TNF-blocker medicines, including Enbrel, the chances of getting lymphoma or other cancers may increase.
- People with rheumatoid arthritis or psoriasis, especially those with very active disease, may be more likely to get lymphoma.

Also, BEFORE starting Enbrel, tell your doctor:

What is Enbrel?
Enbrel is a prescription medicine called a Tumor Necrosis Factor (TNF) blocker. Enbrel is used to treat:
- moderately to severely active rheumatoid arthritis (RA). Enbrel can be used alone or with a medicine called methotrexate.
- psoriatic arthritis. Enbrel can be used alone or with methotrexate.
- ankylosing spondylitis (AS).
- chronic moderate to severe plaque psoriasis in adults ages 18 years and older.
- • moderately to severely active polyarticular juvenile idiopathic arthritis (JIA) in children ages 2 years and older.
You may continue to use other medicines that help treat your condition while taking Enbrel, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and prescription steroids, as recommended by your doctor.
Enbrel can help reduce joint damage and the signs and symptoms of the above mentioned diseases. People with these diseases have too much of a protein called tumor necrosis factor (TNF), which is made by your immune system. Enbrel can reduce the effect of TNF in the body and block the damage that too much TNF can cause, but it can also lower the ability of your immune system to fight infections. See "What is the most important information I should know about Enbrel?" and "What are the possible side effects of Enbrel?"
Who should not use Enbrel?
Do not use Enbrel if you:
- have an infection that has spread through your body (sepsis).
How should I use Enbrel?
- Enbrel is given as an injection under the skin (subcutaneous or SC).
- If your doctor decides that you or a caregiver can give the injections of Enbrel at home, you or your caregiver should receive training on the right way to prepare and inject Enbrel. Do not try to inject Enbrel until you have been shown the right way by your doctor or nurse.
- Enbrel is available in the forms listed below. Your doctor will prescribe the type that is best for you.
- Single-use Prefilled Syringe
- Single-use Prefilled SureClick Autoinjector
- Multiple-use Vial
- See the detailed "Instructions for Use" with this Medication Guide for instructions about the right way to store, prepare, and give your Enbrel injections at home.
- Your doctor will tell you how often you should use Enbrel. Do not miss any doses of Enbrel. If you forget to use Enbrel, inject your dose as soon as you remember. Then, take your next dose at your regular(ly) scheduled time. In case you are not sure when to inject Enbrel, call your doctor or pharmacist. Do not use Enbrel more often than as directed by your doctor.
- Your child's dose of Enbrel depends on his or her weight. Your child's doctor will tell you which form of Enbrel to use and how much to give your child.
What are the possible side effects of Enbrel?
See "What is the most important information I should know about Enbrel?"
Enbrel can cause serious side effects, including:
- Infections. Enbrel can make you more likely to get infections or make any infection that you have worse. Call your doctor right away if you have any symptoms of an infection. See "Before starting Enbrel, be sure to talk to your doctor" for a list of symptoms of infection.
- Hepatitis B infection in people who carry the virus in their blood. If you are a carrier of the hepatitis B virus (a virus that affects the liver), the virus can become active while you use Enbrel. Your doctor may do a blood test before you start treatment with Enbrel and while you use Enbrel.
- Nervous system problems. Rarely, people who use TNF-blocker medicines have developed nervous system problems such as multiple sclerosis, seizures, or inflammation of the nerves of the eyes. Tell your doctor right away if you get any of these symptoms: numbness or tingling in any part of your body, vision changes, weakness in your arms and legs, and dizziness.
- Blood problems. Low blood counts have been seen with other TNF-blocker medicines. Your body may not make enough of the blood cells that help fight infections or help stop bleeding. Symptoms include fever, bruising or bleeding very easily, or looking pale.
- Heart failure including new heart failure or worsening of heart failure you already have. New or worse heart failure can happen in people who use TNF-blocker medicines like Enbrel. If you have heart failure your condition should be watched closely while you take Enbrel. Call your doctor right away if you get new or worsening symptoms of heart failure while taking Enbrel, such as shortness of breath or swelling of your lower legs or feet.
- Psoriasis. Some people using Enbrel developed new psoriasis or worsening of psoriasis they already had. Tell your doctor if you develop red scaly patches or raised bumps that may be filled with pus. Your doctor may decide to stop your treatment with Enbrel.
- Allergic reactions. Allergic reactions can happen to people who use TNF-blocker medicines. Call your doctor right away if you have any symptoms of an allergic reaction. Symptoms of an allergic reaction include a severe rash, a swollen face, or trouble breathing.
- Autoimmune reactions, including:
- Lupus-like syndrome. Symptoms include a rash on your face and arms that gets worse in the sun. Tell your doctor if you have this symptom. Symptoms may go away when you stop using Enbrel.
- Autoimmune hepatitis. Liver problems can happen in people who use TNF-blocker medicines, including Enbrel. These problems can lead to liver failure and death. Call your doctor right away if you have any of these symptoms: feel very tired, skin or eyes look yellow, poor appetite or vomiting, pain on the right side of your stomach (abdomen).
Common side effects of Enbrel include:
- Injection site reactions such as redness, swelling, itching, or pain. These symptoms usually go away within 3 to 5 days. If you have pain, redness, or swelling around the injection site that doesn't go away or gets worse, call your doctor.

These are not all the side effects with Enbrel. Tell your doctor about any side effect that bothers you or does not go away.
