Aciclovir Tablets: What They Are and When to Use Them

Aciclovir tablets are an oral antiviral drug that fights the herpes family of viruses. You’ll usually see them prescribed for cold sores, genital herpes, or shingles. They work by stopping the virus from copying itself, which reduces the severity and duration of outbreaks.

How to Take Aciclovir – Dosage Basics

Dosage depends on the infection and your doctor’s advice. For a cold sore, most adults start with 200 mg five times a day for five days. Genital herpes often requires 200 mg five times a day for 10 days during a first outbreak, then shorter courses for recurrences. Shingles typically needs 800 mg five times a day for seven days. Always follow the exact schedule your doctor gives you. Skipping doses can let the virus bounce back.

Take the tablets with a full glass of water. If you have a sensitive stomach, you can take them with food, but don’t crush or chew them – the tablet form is designed to release the medicine slowly.

Common Side Effects & When to Call a Doctor

Most people tolerate aciclovir well. The most common complaints are mild stomach upset, headache, or a feeling of tiredness. These usually go away on their own. Rarely, you might notice a rash, swelling, or trouble breathing – those are signs of an allergic reaction and need immediate medical attention.

If you notice persistent vomiting, severe diarrhea, or unexplained bruising, call your doctor. Those could be signs the drug is affecting your kidneys or blood cells, especially if you have existing kidney issues.

Buying Aciclovir Safely – Online or In‑Store

In most countries you need a prescription to get aciclovir tablets. When you walk into a pharmacy, show the prescription and ask the pharmacist any questions about brand vs. generic options. Generic aciclovir is usually cheaper and works the same.

If you prefer buying online, choose a licensed pharmacy that requires a prescription. Look for clear contact details, a pharmacist’s name, and real customer reviews. Avoid sites that sell “no‑Rx” aciclovir – they could be counterfeit and unsafe.

Tips for Managing an Outbreak

Start the medication as soon as you feel the first signs of an outbreak – tingling, itching, or a small bump. Early treatment cuts the time the sore stays open and reduces the chance of spreading the virus to others.

Keep the affected area clean and dry. Use a lip balm with sunscreen for cold sores, and avoid sexual contact during a genital herpes flare unless you use protection. Staying hydrated and getting enough rest also helps your immune system fight the virus faster.

Aciclovir tablets are a solid tool in the fight against herpes viruses, but they work best when you take them correctly, watch for side effects, and get them from a trusted source. Talk to your doctor if you have any doubts – they can adjust the dose or suggest alternatives that fit your health needs.
