What is Kevzara?
Kevzara is an injectable prescription medicine called an Interleukin-6 (IL-6) receptor blocker. Kevzara is used to treat adults with moderately to severely active rheumatoid arthritis (RA) after at least one other medicine called a disease modifying antirheumatic drug (DMARD) has been used and did not work well or could not be tolerated.
It is not known if Kevzara is safe and effective in children.
What is the most important information I should know about Kevzara?
Kevzara can cause serious side effects including:
1. Serious Infections. Kevzara is a prescription medicine that affects your immune system. Kevzara can lower the ability of your immune system to fight infections. Some people have serious infections while using Kevzara, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have died from these infections.
Your healthcare provider should test you for TB before starting Kevzara.
- Your healthcare provider should monitor you closely for signs and symptoms of TB during treatment with Kevzara.
You should not start using Kevzara if you have any kind of infection unless your healthcare provider says it is okay.
Before starting Kevzara, tell your healthcare provider if you:
- think you have an infection or have symptoms of an infection, with or without a fever:
- sweats or chills
- muscle aches
- shortness of breath
- blood in your phlegm
- weight loss
- warm, red or painful skin or sores on your body
- diarrhea or stomach pain
- burning when you urinate or urinating more often than normal
- feeling very tired
- are being treated for an infection.
- get a lot of infections or have infections that keep coming back.
- have diabetes, HIV, or a weak immune system. People with these conditions have a higher chance of getting infections.
- have TB, or have been in close contact with someone with TB.
- live or have lived, or have traveled to certain parts of the country (such as the Ohio and Mississippi River valleys and the Southwest) where there is an increased chance of getting certain fungal infections (histoplasmosis, coccidioidomycosis, or blastomycosis). These infections may happen more often or become more severe if you use Kevzara. Ask your healthcare provider if you do not know if you have lived in an area where these infections are common.
- have or have had hepatitis.
After starting Kevzara, call your healthcare provider right away if you have any symptoms of an infection.
2. Changes in certain laboratory test results.
Your healthcare provider should do blood tests before you start Kevzara, 4 to 8 weeks after starting Kevzara, and then every 3 months during treatment to check for:
- low neutrophil count. Neutrophils are white blood cells that help the body fight off bacterial infections. A low neutrophil count is common with Kevzara, and can be severe.
- low platelet count. Platelets are blood cells that help with blood clotting and stop bleeding.
- increase in certain liver function tests. An increase in certain liver function tests is common with Kevzara, and can be severe.
Your healthcare provider may not prescribe Kevzara if your neutrophil or platelet counts are too low, or your liver function tests are too high. Your healthcare provider may stop your Kevzara treatment for a period of time or change your dose if needed because of changes in these blood test results.
Your healthcare provider should do blood tests 4 to 8 weeks after starting Kevzara and then every 6 months during treatment to check for an:
- increase in blood cholesterol levels.
3. Tears (perforation) of the stomach or intestines. Tell your healthcare provider if you have had a condition known as diverticulitis (inflammation in parts of the large intestine) or ulcers in your stomach or intestines. Some people using Kevzara get tears in their stomach or intestine. This happens most often in people who also take nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, or methotrexate. Call your healthcare provider right away if you have fever and stomach (abdominal) pain that does not go away.
4. Cancer. Kevzara may increase your risk of certain cancers by changing the way your immune system works. Tell your healthcare provider if you have ever had any type of cancer.
