Zovirax (acyclovir): What it treats and how to use it safely

Here’s the short version: Zovirax is a well-known antiviral (acyclovir) used for cold sores, genital herpes, and shingles. It comes as a cream, tablet, and IV form. People take it to shorten outbreaks, reduce pain, and help sores heal faster. If you’ve ever wondered whether Zovirax fits your situation or how to buy it online without getting scammed, this page gives straight, practical advice.

How Zovirax works and common uses

Acyclovir stops the virus from copying itself. That doesn’t cure herpes, but it reduces how long and how severe an outbreak is. For cold sores, you might use the topical cream at the first tingle. For genital herpes or shingles, doctors usually prescribe oral tablets. Pregnant people, newborns, and seriously ill patients may get IV acyclovir in hospital settings. Always follow a clinician’s guidance—doses change based on age, kidney function, and how severe the infection is.

Typical patterns you’ll hear from doctors: start treatment as soon as symptoms appear, keep up the full course even if you feel better, and check with your provider if you have kidney issues or take other meds. Don’t share prescriptions or buy meds without a valid prescription. That’s a fast way to run into counterfeit products or unsafe dosing.

Side effects, interactions, and safety tips

Common side effects are mild: nausea, headache, and sometimes tiredness. Less common but more serious issues include kidney problems or confusion, especially in older adults or people with poor kidney function. Drink enough water while taking acyclovir to help your kidneys process the drug. Mention any other medicines you take; some drugs change how acyclovir is handled by the body.

Thinking about buying Zovirax online? Be careful. Look for a pharmacy that asks for a prescription, shows a real business address, and has clear contact info. Sites that promise no prescription or very cheap, fast pills are red flags. Read reviews and check whether the pharmacy is licensed in its country. Our site has guides like "Ordering Prescription Drugs Online" and reviews of online pharmacies that explain what to watch for when shopping for medications.

If cost is your worry, ask your prescriber about generics—acyclovir tablets are often much cheaper than brand-name Zovirax. Also check patient assistance programs or local pharmacies that offer price-matching. Finally, if you feel odd symptoms after starting acyclovir, stop and contact your healthcare provider right away.
