If you’ve got a cold sore, genital herpes flare‑up, or shingles pain, chances are your doctor mentioned Zovirax. It’s the brand name for acyclovir, an antiviral that stops the virus from multiplying. In plain terms, it helps your body fight back faster so symptoms clear up quicker.
People use Zovirax in three main ways: a cream you rub on skin lesions, tablets you swallow for deeper infections, and sometimes a liquid for kids or people who can’t take pills. The form you get depends on where the virus is and how severe it feels.
Acyclovir mimics one of the building blocks viruses need to copy their DNA. When the virus tries to use it, the process stalls and the virus can’t grow. That’s why you start feeling better after a few doses – the drug is cutting off the virus’s supply line.
Because it targets the virus directly, Zovirax doesn’t cure herpes or shingles forever. It just keeps outbreaks shorter and less painful. For people with frequent flare‑ups, doctors may suggest taking it every day as a preventive measure.
Take tablets exactly as prescribed – usually three times a day for five days for cold sores, or longer for shingles. Skipping doses can let the virus bounce back. If you miss one, take it as soon as you remember unless it’s almost time for the next dose.
Drink plenty of water with each pill. This helps your kidneys clear the drug and reduces the chance of kidney irritation. If you have kidney problems, tell your doctor; they might lower the dose.
Watch out for common side effects: mild nausea, headache, or a bit of dizziness. These usually fade after a few days. Seek medical help if you notice severe rash, trouble breathing, or sudden confusion – those are rare but need attention.
When buying Zovirax online, stick to reputable pharmacies that require a prescription. Look for sites with clear contact info and reviews. Avoid cheap “no‑prescription” offers; they often sell fake medication that can be unsafe.
If you’re pregnant or breastfeeding, discuss Zovirax with your doctor first. Most studies say it’s safe, but professional guidance ensures the right balance for you and your baby.
Finally, remember that lifestyle matters too. Stress, UV exposure, and a weakened immune system can trigger outbreaks. Keep skin clean, use sunscreen on lips, and manage stress to get the most out of Zovirax.
