Kineret Side Effects

Kineret reduces the actions of chemicals in the body that are involved in inflammatory and immune responses.

Kineret is used to treat the symptoms of moderate to severe rheumatoid arthritis in patients who have had an inadequate response to one or more antirheumatic drugs. Kineret may be used in combination with other antirheumatic medications.

In rare cases, people receiving Kineret have developed serious infections. Notify your doctor immediately if you develop a fever, flu-like symptoms, or any other sign of infection. Treatment with Kineret should not be started in patients with active infections or those taking other medicines that may suppress the immune system. The use of Kineret in combination with etanercept (Enbrel), infliximab (Remicade), adalimumab (Humira), or other medicines used to treat rheumatoid arthritis, may also increase the risk of a serious infection. Do not use Kineret without first talking to your doctor if you

  • are currently taking etanercept (Enbrel), infliximab (Remicade), or adalimumab (Humira) to treat rheumatoid arthritis;
  • have an active infection or a history of recurrent infection;
  • have recently been exposed to varicella (chickenpox) virus;
  • have a bone marrow disease;
  • have a suppressed immune system due to a medical condition or treatment with medication;
  • have recently received a live vaccine; or
  • have kidney disease.

You may not be able to use Kineret, or you may require a dosage adjustment or special monitoring during treatment.

If you experience an allergic reaction (difficulty breathing; closing of the throat; swelling of your lips, tongue, or face; or hives), stop using Kineret, and seek emergency medical attention. In rare cases, people receiving Kineret have developed serious infections. Notify your doctor immediately if you develop a fever, flu-like symptoms, or any other sign of infection.

  • nausea or diarrhea;
