Acyclovir Medication Information
The U.S. Food and Drug Administration licensed acyclovir (Zovirax®) to treat shingles, genital herpes, and chickenpox. These conditions are caused by viruses, and the medicine works by preventing the viruses from multiplying. Acyclovir is available in several different forms, including tablets, capsules, and an oral suspension.
Prior to beginning treatment with acyclovir, your healthcare provider needs information on any medical conditions you have and any other drugs you are taking. For example, tell your healthcare provider if you have kidney disease or any allergies, including to food, dyes, or preservatives. Most people tolerate this medication well, but side effects can include nausea, diarrhea, and headaches.
