About ARCALYST

ARCALYST is used to treat adults and children 12 years of age and older with Cryopyrin-Associated Periodic Syndromes (CAPS), including Familial Cold Autoinflammatory Syndrome (FCAS) and Muckle-Wells Syndrome (MWS).


ARCALYST can affect your immune system. ARCALYST can lower the ability of your immune system to fight infections. Serious infections, including life-threatening infections and death have happened in patients taking ARCALYST. Taking ARCALYST can make you more likely to get infections, including life-threatening serious infections, or may make any infection that you have worse.


CAPS are characterized by lifelong, recurrent symptoms of rash, fever/chills, joint pain, eye redness/pain, and fatigue.

  • The symptoms of CAPS may be challenging to diagnose. The diagnosis may be delayed because CAPS are rare and the symptoms often resemble those of other disorders
  • Intermittent symptom flares may be triggered anytime by cooling temperatures, stress, exercise, or unidentified causes
  • Some patients may try to reduce their symptoms by avoiding things that trigger the disease
