Avoid getting a vaccine without first asking your doctor. While you are taking siponimod, some vaccines may not work as well and may not fully protect you from disease.
Receiving a "live" vaccine while using siponimod may cause you to develop an infection. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.
If you need to receive a vaccine, you should stop taking siponimod for at least 1 week ahead of time. After receiving the vaccine, you should wait another 4 weeks before you start taking siponimod again. Do not stop taking siponimod without your doctor's advice.
Always ask your doctor before you stop or start taking Mayzent for any reason.
