Arcalyst (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 without a known cause (such as virus, bacteria, or illness). These symptoms include fever, chills, fatigue, and joint pain. More serious symptoms may involve the bones and joints, the central nervous system (deafness, vision loss, mental impairment), or major organs such as the kidneys.

Arcalyst may treat or prevent the symptoms of Familial Cold Auto-inflammatory Syndrome (FCAS) or Muckle-Wells Syndrome (MWS). However, this medication is not a cure for these inherited conditions.

Arcalyst may also be used for purposes not listed in this medication guide.
