What is rilonacept?
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).
FCAS and MWS are inflammatory disorders in which the body develops certain symptoms in response to cold, heat, stress, or tiredness. These symptoms often include rash, fever, and joint pain, and eye redness or discomfort. More serious symptoms may include deafness or kidney failure.
Rilonacept may treat or prevent the symptoms of Familial Cold Auto-inflammatory Syndrome (FCAS) or Muckle-Wells Syndrome (MWS) in adults and children at least 12 years old.
Rilonacept is also used to control symptoms of a condition called Deficiency of Interleukin-1 Receptor Antagonist (DIRA), in adults and children who weigh at least 22 pounds (10 kilograms). DIRA is a very rare genetic condition that causes a severe inflammatory reaction during the first days of life and can lead to organ failure throughout the body.
Rilonacept is not a cure for these inherited conditions.
Rilonacept is also used to reduce episodes of recurrent pericarditis (RP) in adults and children at least 12 years old. RP can cause pounding heartbeats, trouble breathing, and severe chest pain spreading to your back or neck.
Rilonacept may also be used for purposes not listed in this medication guide.
