1. Why am I using Mayzent?

Mayzent contains the active ingredient siponimod. Mayzent belongs to a group of medicines called sphingosine-1-phosphate (S1P) receptor modulators. Mayzent helps to slow down the effects of multiple sclerosis (MS) such as worsening disability and decline in thinking. It may also slow down the nerve damage caused by MS and increase your time without relapse.

Mayzent is used for the treatment of adult patients with secondary progressive multiple sclerosis (SPMS).
