With relapsing forms of MS, you experience periods of new or worsening symptoms (called relapses).</p><p>Keep reading for more information on MS, including the types that Kesimpta is used to treat.</p><h2>What are the symptoms of MS?</h2><p>MS is a chronic (long-term) condition that affects your brain and spinal cord. Your immune system causes MS by mistakenly attacking the myelin, which is a protective layer wrapped around your nerve fibers. When the immune system attacks myelin, it causes inflammation and lesions in your nervous system. This interferes with how well your brain can communicate with the rest of your body.</p><p>Symptoms of MS can include:</p><ul><li>difficulty walking</li><li>vision problems, such as blurry vision</li><li>problems with speech, such as slurred speech or changes in your speech volume</li><li>pain</li></ul><h2>Who is Kesimpta prescribed for?</h2><p>Kesimpta is prescribed to treat the following types of MS in adults:</p><ul><li>relapsing-remitting MS (RRMS)</li><li>secondary progressive MS (SPMS) that is actively causing symptoms</li></ul><p>Kesimpta is also prescribed to treat clinically isolated syndrome (CIS). With CIS, you have an episode of MS-like symptoms that last 24 hours or longer. CIS is often classified as a type of MS, but it may or may not develop into MS.</p><h2>How does Kesimpta treat MS?</h2><p>MS symptoms occur when your immune system mistakenly attacks myelin, which is a protective layer wrapped around your nerve fibers. This action causes inflammation and lesions in your nervous system, interfering with how well your brain communicates with the rest of your body.</p><p>Kesimpta is a type of drug called a monoclonal antibody. It specifically targets and blocks a certain protein in your immune system. By blocking this protein, Kesimpta suppresses your immune system. This can reduce inflammation in your nervous system and relieve MS symptoms. It can also prevent your immune system from attacking myelin, which can slow or prevent MS from worsening.</p><p>Talk with your doctor or pharmacist if you’d like to learn more about how Kesimpta works to treat MS.</p><h2>Is Kesimpta used in children?</h2><p>No, Kesimpta is not used in children. It’s only approved for treating relapsing forms of MS in adults.

Examples include:</p><ul><li>increased risk of serious infection, including progressive multifocal leukoencephalopathy (PML)</li><li>low level of immunoglobulin M (a certain immune system protein)</li><li>serious reactions after giving your Kesimpta injection, including bronchospasm and shortness of breath</li></ul><p>Call your doctor right away if you have any serious side effects while using Kesimpta. If the side effects seem life threatening or if you think you’re having a medical emergency, call 911 or your local emergency number immediately.</p><blockquote><p>Allergic reaction</p><p>For some people, Kesimpta can cause an allergic reaction.

It works by targeting and blocking specific proteins in your immune system that are thought to play a role in causing MS symptoms. Unlike Kesimpta, chemotherapy does not work by targeting specific proteins in the immune system. Instead, chemotherapy targets all cells in the body that grow rapidly. This includes cancer cells, but it can also affect noncancerous cells such as hair cells and skin cells.</p><p>To learn more about how Kesimpta works, including how it compares with chemotherapy drugs, talk with your doctor or pharmacist.</p><h2>How does Kesimpta compare with Ocrevus?</h2><p>Like Kesimpta, Ocrevus is a monoclonal antibody drug prescribed to treat certain types of MS. But these medications do have some differences.</p><p>Kesimpta and Ocrevus are both FDA-approved to treat relapsing forms of MS. But unlike Kesimpta, Ocrevus is also approved to treat primary progressive multiple sclerosis.</p><p>Kesimpta is given as an injection under the skin. It can be self-injected at home after your doctor or pharmacist shows you how to use it. On the other hand, Ocrevus is given as an intravenous (IV) infusion by your doctor or another healthcare professional. You’ll need to go to a clinic or your doctor’s office to receive Ocrevus doses, or you may be able to receive Ocrevus infusions at home.</p><p>To learn more about how Kesimpta and Ocrevus compare, talk with your doctor or pharmacist.</p><h2>Kesimpta cost</h2><p>The price of Kesimpta depends on several factors.

Brand-name drugs usually cost more than biosimilars.</p><h2>How is Kesimpta used?</h2><p>Below are some key details on how Kesimpta is used to treat MS.</p><h2>What is the usual dosage for Kesimpta?</h2><p>The usual dosage for Kesimpta is 20 milligrams (mg). This dosage is typically injected once weekly for your first 3 weeks of treatment. After that, you’ll skip injecting Kesimpta for 1 week before you switch to a dosage of injecting 20 mg once per month.</p><h2>How do you use Kesimpta?</h2><p>Kesimpta comes as a solution inside single-dose prefilled injection pens or syringes. The drug is given as an injection under the skin.</p><p>When you’re first prescribed Kesimpta, your doctor or pharmacist will show you or a caregiver how to give injections at home. The drug manufacturer also provides step-by-step instructions on how to inject Kesimpta.</p><h2>How often should I inject Kesimpta?</h2><p>When you’re first prescribed Kesimpta, you’ll likely inject the drug once weekly for 3 weeks. Then, you’ll skip injecting Kesimpta for 1 week before you switch to a dosage of injecting 20 mg once per month.</p><p>Once you’re injecting Kesimpta on a monthly basis, try to inject the dose on the same day each month. This helps keep a steady level of the drug in your system, which helps it work effectively for your condition.</p><h2>How effective is Kesimpta?</h2><p>If you’re prescribed Kesimpta, you may wonder how effective it is at treating your condition.</p><p>Clinical trials found Kesimpta effective for treating relapsing forms of MS. Your doctor or pharmacist may be able to provide more details. Or you can read Kesimpta’s prescribing information to learn more.</p><p>The American Academy of Neurology’s guidelines for treating MS do not specifically mention Kesimpta. But they do recommend using a disease-modifying therapy (DMT) to treat relapsing forms of MS. And Kesimpta is considered a DMT because it can help slow the worsening of your MS symptoms over time. Your doctor can provide more information on how they’ll determine which DMT may be best for you.</p><p>To learn more about Kesimpta’s effectiveness, talk with your doctor.</p><p><b>Disclaimer:</b> Healthline has made every effort to make certain that all information is factually correct, comprehensive, and up to date.
