What is Kevzara?

Kevzara (sarilumab) is used to treat rheumatoid arthritis (RA) and polymyalgia rheumatica (PMR) in certain adults, and also active polyarticular juvenile idiopathic arthritis (pJIA) to help reduce pain, stiffness, swelling, and other symptoms.

Kevzara works by blocking the effects of a protein called interleukin-6 (IL-6), which is involved in causing inflammation, by blocking IL-6 reduces the inflammatory process and improves symptoms. Kevzara belongs to the class of medicines known as interleukin-6 receptor antagonists (also called IL-6 inhibitors) and is a type of biologic.

Kevzara is often given after other medications have been tried without successful treatment of symptoms, depending on the condition being treated. It is sometimes given together with other arthritis medicines.
