- Have a weakened immune system, caused by HIV, AIDS, cancer, or other problems
- Have had a reaction to a vaccine in the past

Make sure to tell your healthcare provider about all other medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.

A Zostavax overdose is unlikely, since each vial contains just one dose. Therefore, it is not known what to expect from an overdose.
Your healthcare provider must store Zostavax in the freezer before it is mixed. After it is mixed, it should be given within 30 minutes. It is okay to keep the unmixed vaccine at refrigerator temperature for up to 72 hours (3 days) before mixing and using it. After 72 hours at refrigerator temperature, it must be discarded if not used.
