Rilonacept is used to treat some of the symptoms of rare genetic conditions such as Familial Cold Auto-inflammatory Syndrome (FCAS) or Muckle-Wells Syndrome (MWS). However, this medication is not a cure for these inherited conditions.
Before taking the medicine
You should not use this medication if you are allergic to rilonacept, or if you have any of these conditions:
- an active or chronic infection;
- a history of tuberculosis or recurrent infections; or
- high cholesterol or triglycerides (a type of fat in blood).
After taking the medicine
Serious and sometimes fatal infections may occur during treatment with rilonacept. Call your doctor right away if you have signs of infection such as: fever, chills, sore throat, flu symptoms, easy bruising or bleeding (nosebleeds, bleeding gums), loss of appetite, nausea and vomiting, mouth sores, or unusual weakness.
