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 healthcare provider about your medical condition or treatment. It is important to remain under your healthcare provider's care while using Enbrel.
Enbrel is a prescription medicine called a Tumor Necrosis Factor (TNF) blocker that affects your immune system.

What is the most important information I should know about Enbrel?
Enbrel may cause serious side effects, including:
1. Risk of Infection
2. 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 healthcare provider should test you for TB before starting Enbrel.
  • Your healthcare provider should monitor you closely for symptoms of TB during treatment with Enbrel even if you tested negative for TB.
  • Your healthcare provider 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 healthcare provider says it is okay.
2. Risk of cancer
  • There have been cases of unusual cancers, some resulting in death, 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, especially those with very active disease, may be more likely to get lymphoma.

Before starting Enbrel, be sure to talk to your healthcare provider:

Enbrel may not be right for you. Before starting Enbrel, tell your healthcare provider about all of your medical conditions, including:
Infections. Tell your healthcare provider if you:
  • have an infection. See "What is the most important information I should know about Enbrel?"
  • are being treated for an infection.
  • think you have an infection.
  • have symptoms of an infection such as fever, sweats or chills, cough or flu-like symptoms, shortness of breath, blood in your phlegm, weight loss, muscle aches, warm, red or painful areas on your skin, sores on your body, diarrhea or stomach pain, burning when you urinate or urinating more often than normal, and feel very tired.
  • have any open cuts on your body.
  • get a lot of infections or have infections that keep coming back.
  • have diabetes, HIV, or a weak immune system. People with these conditions have a higher chance for infections.
  • have TB, or have been in close contact with someone with TB.
  • were born in, lived in, or traveled to countries where there is a risk for getting TB. Ask your healthcare provider if you are not sure.
  • live, have lived in, or traveled to certain parts of the country (such as the Ohio and Mississippi River valleys, or the Southwest) where there is a greater risk for getting certain kinds of fungal infections (histoplasmosis, coccidioidomycosis, blastomycosis). These infections may happen or become more severe if you use Enbrel. Ask your healthcare provider if you do not know if you live or have lived in an area where these infections are common.
  • have or have had hepatitis B.
Also, before starting Enbrel, tell your healthcare provider:
  • About all the medicines you take including prescription and over-the-counter medicines, vitamins and herbal supplements including:
    • Orencia (abatacept) or Kineret (anakinra). You have a higher chance for serious infections when taking Enbrel with Orencia or Kineret.
    • Cyclophosphamide (Cytoxan). You may have a higher chance for getting certain cancers when taking Enbrel with cyclophosphamide.
    • Anti-diabetic medicines. If you have diabetes and are taking medication to control your diabetes, your healthcare provider may decide you need less anti-diabetic medicine while taking Enbrel.
Keep a list of all your medications with you to show your healthcare provider and pharmacist each time you get a new medicine. Ask your healthcare provider if you are not sure if your medicine is one listed above.
Other important medical information you should tell your healthcare provider before starting Enbrel, includes if you:
  • have or had a nervous system problem such as multiple sclerosis or Guillain-Barré syndrome.
  • have or had heart failure.
  • are scheduled to have surgery.
  • have recently received or are scheduled to receive a vaccine.
    • All vaccines should be brought up-to-date before starting Enbrel.
    • People taking Enbrel should not receive live vaccines.
    • Ask your healthcare provider if you are not sure if you received a live vaccine.
  • are allergic to rubber or latex.
    • The needle covers on the single-dose prefilled syringes, the needle covers within the white caps on the single-dose prefilled SureClick autoinjectors, and within the purple caps of the Enbrel Mini cartridges contain dry natural rubber.
  • have been around someone with varicella zoster (chicken pox).
  • are pregnant or plan to become pregnant. It is not known if Enbrel will harm your unborn baby. If you took Enbrel during pregnancy, talk to your healthcare provider prior to administration of live vaccines to your infant.
  • are breastfeeding or plan to breastfeed. Enbrel can pass into breast milk. Talk to your healthcare provider about the best way to feed your baby while taking Enbrel.
See the section "What are the possible side effects of Enbrel?" below for more information.
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.
  • moderately to severely active polyarticular juvenile idiopathic arthritis (JIA) in children ages 2 years and older.
  • psoriatic arthritis (PsA). Enbrel can be used alone or with methotrexate.
  • ankylosing spondylitis (AS).
  • chronic moderate to severe plaque psoriasis (PsO) in children 4 years and older and adults who may benefit from taking injections or pills (systemic therapy) or phototherapy (ultraviolet light).
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 healthcare provider.
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 healthcare provider 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 healthcare provider or nurse.

    • Single-dose Prefilled Syringe
    • Single-dose Prefilled SureClick Autoinjector
    • Single-dose Vial

Then, take your next dose at your regular(ly) scheduled time. In case you are not sure when to inject Enbrel, call your healthcare provider or pharmacist. Do not use Enbrel more often than as directed by your healthcare provider.
  • Your child's dose of Enbrel depends on his or her weight. Your child's healthcare provider will tell you which form of Enbrel to use and how much to give your child.

What are the possible side effects of Enbrel?
Enbrel can cause serious side effects, including:

  • See "What is the most important information I should know about Enbrel?"
  • Infections. Enbrel can make you more likely to get infections or make any infection that you have worse. Call your healthcare provider right away if you have any symptoms of an infection. See "Before starting Enbrel, be sure to talk to your healthcare provider" for a list of symptoms of infection.
  • Previous Hepatitis B infection. If you have been previously infected with the hepatitis B virus (a virus that affects the liver), the virus can become active while you use Enbrel. Your healthcare provider 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 healthcare provider 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 healthcare provider 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 healthcare provider if you develop red scaly patches or raised bumps that may be filled with pus. Your healthcare provider may decide to stop your treatment with Enbrel.
  • Allergic reactions. Allergic reactions can happen to people who use TNF-blocker medicines. Call your healthcare provider 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 healthcare provider 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 healthcare provider 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, itching, pain, swelling, bleeding or bruising. These symptoms usually go away within 3 to 5 days. If you have pain, redness, or swelling around the injection site that does not go away or gets worse, call your healthcare provider.
  • Upper respiratory infections (sinus infections).
These are not all the side effects with Enbrel. Tell your healthcare provider about any side effect that bothers you or does not go away.
Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
