Acyclovir: What It Is and How It Works

Ever wondered what acyclovir is all about? It's a prescription antiviral medicine most known for treating infections caused by herpes viruses, like cold sores, genital herpes, and shingles. Basically, it works by slowing down the virus, helping your body's defenses catch up so you can heal faster.

Without acyclovir, these infections can linger or flare up more often. But taking this medication can shorten outbreaks and reduce discomfort. It’s pretty popular because it targets the virus specifically without affecting the rest of your body much.

When and How to Use Acyclovir

You usually take acyclovir orally in pills, but there are creams and injections too, depending on how severe your infection is. Doctors often recommend starting treatment as soon as symptoms begin, like that tingling before a cold sore appears. The sooner you start, the better it works.

Stick to the prescribed dosage and finish the course even if you feel better early on. Skipping doses or stopping too soon can give the virus a chance to rebound. If you have kidney problems or take other medicines, check with your doctor to avoid issues.

What to Expect and Watch Out For

Most people tolerate acyclovir well. Some folks might notice mild nausea, headache, or dizziness, which usually fades. Serious side effects are rare but call your doctor if you notice swelling, rash, or confusion.

Remember, acyclovir helps manage symptoms but doesn't cure herpes or stop it from coming back later. Using condoms and avoiding skin contact during outbreaks is still key to preventing spread.
