Siponimod, sold under the brand name Mayzent, is a medication used to treat multiple sclerosis (MS). Specifically it is used for relapsing forms of MS including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. It is taken by mouth.

Common side effects include headache, high blood pressure, and liver problems. Other side effects may include infection, macular edema, arrhythmias, and posterior reversible encephalopathy syndrome. It should not be used in people who are allergic to peanuts or to soya. It works by blocking sphingosine-1-phosphate receptors.

Siponimod was approved for medical use in the United States in 2019 and Europe in 2020. At a dose of 2 mg per day, it costs about 8,400 USD per month in the United States as of 2021. In the United Kingdom this amount costs the NHS about £1,800. In the United States it is only available through a specialty pharmacy.
