Ozanimod — Uses, Dosage, Side Effects & Safety

Drug class: Sphingosine 1-phosphate (S1P) receptor modulator

Overview

Ozanimod is a prescription medication used to treat adults with relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. It is also approved for the treatment of moderately to severely active ulcerative colitis in adults. Ozanimod works by modulating the immune system. It blocks certain immune cells (lymphocytes) from leaving lymph nodes, which reduces their ability to cause inflammation and damage in the central nervous system or the colon. Key points for patients: Ozanimod is taken once daily by mouth. It requires a gradual dose increase (titration) when starting to reduce the risk of side effects. Regular blood tests and heart monitoring may be needed before and during treatment. Always follow your healthcare provider’s instructions and report any unusual symptoms.
