If you’ve ever searched for a cure for cold sores, genital herpes, or the painful rash of shingles, chances are acyclovir popped up. It’s an antiviral medication that stops the virus from multiplying, which helps your body heal faster and reduces how long symptoms last.
Acyclovir comes in tablets, capsules, and a liquid form. The exact dose depends on what you’re treating. For cold sores, doctors often prescribe 200 mg five times a day for five days. Genital herpes outbreaks usually need 400 mg three times daily for 7‑10 days, while suppressive therapy may be just one 400 mg tablet once a day. Shingles treatment typically starts with 800 mg five times a day for seven to ten days.
Take the medication with plenty of water and try to keep the timing consistent – your body does better when levels stay steady. If you miss a dose, take it as soon as you remember unless it’s almost time for the next one; then just skip the missed pill and continue as usual. Don’t double‑dose.
Food doesn’t usually affect acyclovir absorption, so you can take it with or without meals. However, if you have kidney problems, your doctor might lower the dose because the drug is cleared through the kidneys.
Many people look for cheaper options online, but not every site is trustworthy. Stick to pharmacies that require a valid prescription and display clear licensing information. Look for seals from recognized pharmacy verification programs and read recent customer reviews.
Avoid sites that promise “no prescription needed” or ultra‑low prices that seem too good to be true – they often sell counterfeit pills that could be ineffective or even harmful. If you’re unsure, compare the price with a few reputable U.S. or Canadian online pharmacies; a small difference is normal, but huge discounts are red flags.
When you receive your order, check the packaging for proper labeling, batch numbers, and expiration dates. Keep the medication in a cool, dry place, away from direct sunlight, to preserve potency.
If you notice any unusual side effects – like severe headache, rash, or sudden kidney pain – stop taking acyclovir and call your doctor right away. Common mild side effects include nausea, diarrhea, and occasional dizziness, which usually pass on their own.
Remember, acyclovir works best when you start it early in an outbreak. For cold sores, begin treatment at the first sign of tingling or redness. For shingles, the sooner you start (ideally within 72 hours), the less intense the pain will be.
Overall, acyclovir is a safe and effective tool for managing several viral infections when used as directed. Pair it with good hygiene – wash hands often, avoid sharing towels or lip balm during an outbreak – and you’ll cut down on spreading the virus to others.
