Acyclovir is used to treat viral infections like herpes simplex, which causes cold sores and genital herpes, and varicella-zoster, which causes chickenpox and shingles. It helps reduce symptoms such as pain, itching, and blisters by slowing the virus's growth.
Acyclovir works by interfering with the virus's ability to replicate, which means it stops the virus from making more copies of itself. This action helps reduce symptoms and speed up healing in infections like herpes simplex and varicella-zoster.
Acyclovir is usually taken orally in pill form, but it can also be given as a cream or an injection. The typical dose for adults treating herpes simplex is 200 mg five times a day. Always follow your doctor's specific dosing instructions.
Common side effects of acyclovir include nausea, diarrhea, and headache, which are usually mild. Serious side effects like kidney problems or severe allergic reactions are rare. If you notice any new or worsening symptoms, contact your doctor immediately.
Acyclovir can cause kidney problems, especially in people with pre-existing kidney issues. Drink plenty of water to help prevent kidney damage. Don't take acyclovir if you're allergic to it. Always consult your doctor about any concerns or conditions before starting acyclovir.
