If you miss a dose or forget to use your medicine, use it as soon as you can. If it is almost time for your next dose, wait until then to use the medicine and skip the missed dose. Do not use extra medicine to make up for a missed dose.

Warnings While Using Acyclovir Oral:

Make sure your doctor knows if you are pregnant or breast feeding. Tell your doctor if you have kidney disease or a weak immune system. Some things that cause a weak immune system are cancer chemotherapy, HIV/AIDS, recent infection, or recent bone marrow or kidney transplant.

Acyclovir will not stop the spread of herpes during sex. Avoid having sex while you have herpes sores.
