Side Effects


Like any medicine, Enbrel® has risks and benefits and may cause some side effects. The most common ones are mild and temporary. The important thing is to talk to your doctor or pharmacist if you notice anything unusual or if you have any concerns.


  • Common, mild reactions
    Most injections can cause a mild reaction around the injection site. The reactions may include itching, soreness, redness, swelling, bleeding or pain at the injection site. Generally, injection site reactions are not severe and do not occur as often after the first month of treatment.
    Infections, including colds and sinus infections are very common.

  • Less common side effects
    Although they may be unrelated to Enbrel®, there are a number of minor health problems, such as headache, runny nose or rash, which you should tell your doctor about if they become persistent.

  • Other side effects not listed above may also occur in some patients. Tell your doctor if you notice anything else that is making you unwell.
    There have been reports of some types of cancer developing in patients using Enbrel® and other TNF blocking medicines. These include skin cancers, cancers that affect the lymph system called lymphoma and Kaposi’s sarcoma (which also affects the organs, skin, mouth, nose or throat), or affect the blood system called leukaemia. The role of Enbrel® in the development of cancer is not known.

    Do not be alarmed by this list of possible side effects. You may not experience any of them.
