What is rilonacept (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.
Rilonacept 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.
Rilonacept may also be used for purposes not listed in this medication guide.

What is the most important information I should know about rilonacept (Arcalyst)?
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.
You should not use this medication if you are allergic to rilonacept, or if you have any type of infection.
Before using rilonacept, tell your doctor if you have an active or chronic infection, a history of tuberculosis or recurrent infections, or high cholesterol or triglycerides. Make sure you are current on all vaccines before you start treatment with rilonacept.
Tell your doctor about all other medications you use, especially drugs to treat arthritis, psoriasis, Crohn's disease, or ankylosing spondylitis.
Do not receive a "live" vaccine while using rilonacept. The vaccine may not work as well during this time, and may not fully protect you from disease. Avoid coming into contact with anyone who has recently received a live vaccine. There is a chance that the virus could be passed on to you.
