Acyclovir – What You Need to Know

If you’ve been prescribed acyclovir or are thinking about it, you probably want the basics fast: how it works, how to take it, and what might happen while you’re on it. In plain terms, acyclovir is an antiviral medication that stops certain viruses – mainly herpes simplex (cold sores and genital herpes) and varicella‑zoster (shingles) – from multiplying.

Why does that matter? When the virus can’t make copies of itself, your body’s immune system gets a chance to catch up, which means fewer outbreaks, quicker healing, and less pain. That’s the core idea behind every acyclovir prescription you’ll see on HeyDoctor.com.

How to Take Acyclovir Correctly

The key to getting results is sticking to the schedule your doctor gave you. Most people take acyclovir three times a day for cold sores, or five times a day for shingles, but the exact timing can differ based on the brand (tablet, suspension, cream) and the infection type.

• Oral tablets: Swallow with water. Don’t crush unless your doctor says so.
• Cream: Apply a thin layer to the affected skin after washing your hands. Use it five times a day for cold sores.
• Suspension (liquid): Measure with a proper dosing spoon or syringe. Children often use this form.

Take each dose at evenly spaced intervals – for example, every eight hours if you’re on a three‑times‑daily schedule. Setting an alarm can help keep the rhythm.

Common Side Effects and When to Call Your Doctor

Acyclovir is generally safe, but like any drug it can cause unwanted reactions. The most common are mild:

• Nausea or stomach upset
• Headache
• Dry mouth
• Skin rash (usually not serious)

If you notice a severe rash, fever, confusion, or trouble breathing, stop the medication and seek medical help right away. Those could signal an allergic reaction.

Kidney problems are rare but can happen, especially if you’re dehydrated or taking other kidney‑affecting drugs. Staying hydrated – drinking plenty of water – helps lower that risk.

Women who are pregnant or nursing should discuss acyclovir with their doctor. In most cases it’s considered safe, but only a professional can weigh the benefits against any potential risks for you and your baby.

Tips to Maximize Benefits

Here are some practical steps that make acyclovir work better:

• Start early: For cold sores, begin treatment at the first sign of tingling or itching. Early use shortens the outbreak.
• Avoid touching lesions: This prevents spreading the virus to other body parts or people.
• Combine with good hygiene: Wash your hands frequently, especially after applying cream.
• Don’t skip doses: Missing a dose can let the virus bounce back.

Remember, acyclovir won’t cure herpes forever; it just controls outbreaks. Keeping stress low, getting enough sleep, and eating well also help keep flare‑ups at bay.
