Kevzara (sarilumab) is a medication that's used for inflammatory problems called rheumatoid arthritis (RA) and polymyalgia rheumatica (PMR). It's an injection under the skin (subcutaneous or subQ) that can be given at home after you receive instructions from your healthcare provider on how to properly administer the medication. The dose is typically given once every 2 weeks. Side effects include pain and itchiness at the injection site.
Moderate-to-severe rheumatoid arthritis (RA)
Kevzara (sarilumab) is a monoclonal antibody that's called an interleukin-6 inhibitor. Interleukin-6 (IL-6) is a protein in your body that plays a key role in causing inflammation in your joints, leading to symptoms like joint swelling and pain. By blocking IL-6, Kevzara (sarilumab) lowers inflammation and helps relieve symptoms.

Side effects that you should report to your care team as soon as possible:
Side effects that usually do not require medical attention (report to your care team if they continue or are bothersome):
Given once every 2 weeks
Can inject the medication at home yourself after you get trained on how to use it properly
Good option if you haven't had improvement with other RA medications or with steroids for PMR
Needs to be given as an injection under the skin
Raises the risk of infection
Requires occasional lab testing
Kevzara (sarilumab) can raise your risk of getting a serious or life-threatening infection. Get medical help right away if you develop symptoms of an infection (e.g., fever, cough, difficulty breathing, diarrhea, weakness, sweating, chills) while you're taking Kevzara (sarilumab). You might have to stop taking Kevzara (sarilumab) so your body can fight and fully recover from the infection.
Avoid getting live vaccines while you're taking Kevzara (sarilumab) since it's not known how your body will respond to it during treatment. Before getting any vaccines, let your provider or pharmacist know that you're taking Kevzara (sarilumab). Talk to them if you're not sure whether you can receive the vaccine.
Tips on how to use Kevzara (sarilumab):
You should receive training from your provider or pharmacist on how to inject Kevzara (sarilumab) safely and properly. Carefully review the instructions for use for the prefilled pen or syringe (whichever one you have). Contact your provider or pharmacist if you have any questions.
Keep Kevzara (sarilumab) in the original carton to protect it from light. Place the cartons in the refrigerator. If you're traveling and don't have access to a refrigerator, you can keep the medication at room temperature for up to 14 days. Once it's been out at room temperature, don't place the medication back in the refrigerator.
Before it's time for your dose, take the medication out of the refrigerator, and lay it on a flat surface to warm up. This will take about 30 minutes for the prefilled syringe and 60 minutes for the prefilled pen. Don't try to warm up the medication any other way.
Look at the liquid inside the syringe or pen to make sure it's clear to a slightly yellow color. It also might have some air bubbles in it, which is normal. But it shouldn't have any particles (solid chunks) floating around in it. Don't use the medication if the liquid is cloudy, discolored, or has particles. Instead, call your provider or pharmacist for a replacement.
Inject Kevzara (sarilumab) into the fatty part of the skin either on top of your thigh or at your stomach (at least 2 inches away from the belly button). You can also ask someone to help inject the medication into the fatty part of the skin at the back of your upper arm. Don't inject into skin that's scarred, tender, bruised, or damaged. Be sure to switch between injection areas to avoid pain.
After injecting the medication, throw away the Kevzara (sarilumab) syringe or pen in a sharps container or something made of heavy-duty plastic, such as an empty milk carton or laundry detergent bottle. This helps lower the risk of needle-stick injuries. Don't throw away needles or syringes in your trash can. For guidance on how to throw away your sharps container safely for your specific state, visit the FDA's website.
Kevzara (sarilumab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Active, chronic, or recurrent infection | Age 65 years and older | Having other conditions that raise your risk of infection | Living in or traveling to places with high rates of TB or fungal infections | Taking medications that weaken your immune system (e.g., steroids, methotrexate)
Kevzara (sarilumab) can affect your body's ability to fight off infections. This raises your risk of serious and sometimes life-threatening bacterial, viral, or fungal infections. Treatment with Kevzara (sarilumab) can also cause new or old tuberculosis (TB) infections to come back. Similarly, the medication can reactivate (wake up) the hepatitis B virus (HBV) if you're a carrier of the virus. For these reasons, you'll need to get tested for both TB and HBV before starting Kevzara (sarilumab) and get treatment if you test positive (meaning you're infected with TB or HBV).
Tell your provider about your medical conditions and medications so they can make sure Kevzara (sarilumab) is safe for you. Go to the hospital right away to get examined for an infection if you develop fever, cough, difficulty breathing, diarrhea, weakness, sweating, or chills while taking Kevzara (sarilumab). You might have to stop taking Kevzara (sarilumab) so your body can fight the infection.
People taking Kevzara (sarilumab) have reported having low blood cell counts. This can raise the risk of serious infections, bleeding, and anemia. If your blood counts drop too low, you'll probably need to stop taking Kevzara (sarilumab). Contact your provider right away if you develop any signs of infection (e.g., fever, tiredness, chills, cough, trouble breathing). Also call your provider if you notice signs of blood problems (pale skin, fast heart rate, lightheadedness, blood in your urine or stool).
Kevzara (sarilumab) can also raise your cholesterol, triglycerides, and liver function tests.
Your provider will order blood tests for you every so often throughout treatment to monitor your lab values. This makes sure Kevzara (sarilumab) isn't harming you.
Risk factors: History of stomach problems | Taking oral (by mouth) steroids or NSAIDs
In clinical studies, some people taking Kevzara (sarilumab) had stomach problems, including infection, inflammation, or a tear in the wall of the gut. Some of these problems can be dangerous and can require hospitalization. Before starting Kevzara (sarilumab), let your provider know if you have a history of bowel or gut-related problems. Some symptoms to notify your provider about right away include sudden and severe stomach pain, nausea, vomiting, stomach swelling or bloating, fever, and chills.
Allergic reactions to Kevzara (sarilumab) are possible. Most common reactions reported were rash at the injection site, a general rash, and hives. But allergic reactions can also include life-threatening reactions like facial swelling, shock, and anaphylaxis (closing of the throat). Get medical attention right away if you notice rash, hives, dizziness, a choking sensation, difficulty breathing, swelling around your eyes, or swelling of the lips or tongue after using Kevzara (sarilumab).
A good way to avoid certain infections is to make sure that you're up to date on your vaccinations. Talk to your provider about what vaccines you need before starting Kevzara (sarilumab). Once you start treatment with Kevzara (sarilumab), you'll need to avoid live vaccines, such as the MMR vaccine, nasal spray version of the flu vaccine, and the Varivax (varicella) vaccine. It's not clear how safe it is to get live vaccines while you're taking Kevzara (sarilumab).
The typical dose is 200 mg injected under the skin once every 2 weeks.
Your provider might lower your dose based on your lab test results (e.g., blood cell counts, liver tests) and whether you're having side effects (e.g., infections).
