Infusion reactions. Uplizna can cause infusion reactions that can be serious or may cause you to be hospitalized. You will be monitored during your infusion and for at least 1 hour after each infusion of Uplizna for signs and symptoms of an infusion reaction. Tell your healthcare provider right away if you get any of these symptoms:

• Vaccinations. Certain vaccines, called “live” or “live attenuated” vaccines, are not recommended in people receiving Uplizna. Talk to your healthcare provider before receiving any vaccinations. If you have a baby and you were receiving Uplizna during pregnancy, it is important to tell your baby’s healthcare provider about your Uplizna use so they can decide when your baby should receive any vaccine.
