This medication is used to treat multiple sclerosis (MS). Ozanimod is not a cure for MS but it is thought to help by preventing immune system cells (lymphocytes) from attacking the nerves in your brain and spinal cord. It helps decrease the number of episodes of disease worsening (relapses) and may prevent or delay disability.

Ozanimod is also used to treat a certain bowel disease (ulcerative colitis). It helps to reduce symptoms of ulcerative colitis such as diarrhea, rectal bleeding, and stomach pain.

Read the Medication Guide provided by your pharmacist before you start taking ozanimod and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
