Acyclovir Tablets 400mg – What You Need to Know

If you’ve ever dealt with a cold sore, genital herpes, or shingles, you’ve probably heard of acyclovir. It’s the go‑to antiviral for many people, and the 400 mg tablet is the most common strength you’ll find in Canadian pharmacies. In this guide we’ll cover when to use acyclovir, how to take it safely, what side effects to watch for, and the best way to order it online without getting scammed.

How Acyclovir Works and When to Use It

Acyclovir stops the herpes virus from multiplying. It does this by getting inside infected cells and messing up the virus’s DNA. The result? Fewer sores, faster healing, and less chance of spreading the infection to others. You’ll usually take a 400 mg tablet for three main reasons:

• Cold sores (herpes labialis): Start the medication at the first sign of tingling, then keep taking it for 5‑7 days.
• Genital herpes (HSV‑2): Doctors often prescribe a short “burst” course (5 days) after an outbreak, or a daily suppressive dose to cut down on flare‑ups.
• Shingles (herpes zoster): A 7‑10 day course can ease pain and speed up skin healing if you begin treatment within 72 hours of the rash appearing.

In each case the goal is the same: stop the virus before it goes wild. If you wait too long, the medicine won’t be as effective, so act fast when symptoms show up.

Dosage, Safety Tips, and Buying Online

The usual adult dose for most outbreaks is 400 mg taken three times a day (every 8 hours). For suppressive therapy the dose often drops to 400 mg twice daily. Always follow your doctor’s prescription; the timing matters because steady blood levels keep the virus in check.

Common side effects are mild: headache, nausea, or a little stomach upset. If you notice a rash, fever, or feel unusually tired, call your pharmacist or doctor right away. Acyclovir is generally safe for kidneys, but if you have kidney disease the dose may need trimming.

When you’re ready to buy, look for a Canadian‑licensed online pharmacy. Check that the site displays a valid pharmacy licence number, offers a pharmacist‑available chat, and uses secure https connections. Avoid “too good to be true” prices that undercut the market by 50 %—they’re often counterfeit.

Steps to buy safely:

1. Verify the pharmacy’s licence on the Health Canada website.
2. Make sure a prescription is required; reputable stores won’t sell acyclovir without it.
3. Read customer reviews for shipping speed and product quality.
4. Use a payment method that offers buyer protection, like a credit card.
5. Keep a copy of your prescription and the order confirmation in case you need it later.

Once your tablet arrives, store it at room temperature away from moisture. Don’t use it after the expiration date – potency drops and you could get a weaker effect.

That’s the quick rundown on acyclovir 400 mg tablets. They’re a solid, affordable option for keeping herpes‑related outbreaks under control. By following the right dosage, watching for side effects, and buying from a trusted Canadian pharmacy, you can feel confident that you’re getting the real deal and staying healthy.
