Summary
Acyclovir is used to treat viral infections like herpes simplex, which causes cold sores and genital herpes, shingles, which is a painful rash, and chickenpox, which is a contagious disease causing itchy blisters.
Acyclovir works by interfering with the virus's ability to reproduce, which means it stops the virus from multiplying, helping to reduce symptoms and speed up healing.
Acyclovir is usually taken orally, which means by mouth, with or without food. Dosages vary, but for herpes, it might be 200 mg five times a day, and for shingles, 800 mg five times a day.
Common side effects of Acyclovir include nausea, which is feeling sick to your stomach, diarrhea, which is loose or watery stools, and headaches, which are pains in your head.
Acyclovir can cause kidney problems, especially in people with existing kidney issues. It's important to stay hydrated. People allergic to Acyclovir should not use it, and it can interact with other medications.
