How often is Kevzara injected for RA?

Kevzara is injected under the skin once every two weeks for rheumatoid arthritis. The dose is 200 mg, and patients can self-administer it after training.

Patients who miss a dose can inject the next one as soon as they remember unless the next scheduled dose is almost due. In that case, they simply skip the missed dose and keep on the regular schedule.
