Aciclovir is an antiviral drug that fights the herpes family of viruses. It’s commonly prescribed for cold sores, genital herpes, and shingles. If you’ve ever had a painful blister or a rash that just won’t go away, chances are a doctor might suggest Aciclovir to speed up healing.
Aciclovir works by stopping the virus from multiplying. The drug turns into a special form inside infected cells and blocks the viral DNA from copying itself. Without fresh copies, the virus can’t spread, and your immune system gets a chance to clear the infection faster.
Typical doses depend on the condition:
Stick to the schedule your doctor gives you. Skipping doses can let the virus bounce back, and taking more than prescribed won’t make it work faster—just raise the risk of side effects.
Aciclovir is generally well‑tolerated, but watch for common side effects like headache, nausea, or mild kidney irritation. If you notice a rash, dizziness, or sudden swelling, call your doctor right away.
When you need Aciclovir, a prescription is required in most countries. If you’re looking to buy it online, follow these steps:
Once you’ve ordered, store the tablets in a cool, dry place and keep them out of reach of children. Finish the entire course even if you feel better—stopping early can let the virus linger.
In short, Aciclovir is a proven, affordable way to tackle herpes‑related infections. Use it as your doctor directs, be aware of side effects, and only buy from reputable online pharmacies. If you follow these simple rules, you’ll get relief without the hassle of unnecessary risks.
