What is Kevzara?

Kevzara reduces the effects of a  substance in the body  that can cause inflammation.

Kevzara is used to treat moderate to severe  rheumatoid arthritis  in adults. Itis sometimes given together with other arthritis medicines.

Kevzara is usually given after other medications have been tried without successful treatment of symptoms.

Kevzara is also being  studied  in clinical trials as a potential treatment for patients who are severely or critically ill with  COVID-19 .


Kevzara affects your immune system. You may get infections more easily, even serious or fatal infections. Tell your doctor if you have a fever, chills, tiredness, cough,  diarrhea , stomach pain,  weight loss , skin sores, or painful urination.

Kevzara may cause you to have a tear in your stomach or intestines. This is more likely if you have  diverticulitis  or a  stomach ulcer , or if you also take steroids,  methotrexate , or an NSAID (nonsteroidal anti-inflammatory drug). Call your doctor right away if you have a fever and ongoing stomach pain.

Before and during your treatment with Kevzara, you will need frequent blood tests. Your treatment may be delayed or stopped based on the results of these tests.
