Valtrex (valacyclovir) is an antiviral pill that fights the herpes family of viruses. It’s commonly prescribed for cold sores, genital herpes, and shingles. Think of it as a shortcut that turns into acyclovir once it’s inside your body, letting the medicine work faster and longer. If you’ve heard doctors mention Valtrex, they’re usually talking about stopping an outbreak early or easing pain from shingles.
Dosage depends on what you’re treating. For cold sores, most people take 2 grams once a day for a single day. Genital herpes often requires 1 gram twice a day for 10 days (first outbreak) or 500 mg once a day for suppressive therapy. Shingles treatment usually calls for 1 gram three times a day for 7 days. Swallow the tablets with a full glass of water; you don’t need food, but taking it with meals can ease stomach upset.
Don’t skip doses, especially if you’re using Valtrex to stop an outbreak. Missing a dose can let the virus bounce back. If you forget one, take it as soon as you remember—unless it’s almost time for the next dose. Then just skip the missed one and continue as usual.
Most people tolerate Valtrex well. The usual side effects are mild: headache, nausea, or a little tummy upset. Some folks report a rash or feeling unusually tired. If you notice a severe rash, swelling, or difficulty breathing, stop the medicine and seek medical help right away—that could mean an allergic reaction.
Kidney problems can crop up if you take high doses for a long time. If you have a history of kidney disease, tell your doctor; they might lower the dose or check your kidney function during treatment.
For most healthy adults, Valtrex is safe, but always double‑check with a pharmacist or doctor if you’re on other meds, especially other antivirals or certain antibiotics.
Buying Valtrex online? Stick to reputable pharmacies that ask for a valid prescription. Look for SSL certificates (the little padlock in the browser) and clear contact details. Avoid sites that promise “no prescription needed” or unbelievably low prices—those are often counterfeit. If you’re in the UK or US, you can use services like the NHS or your insurance portal to get the prescription sent directly to a trusted online pharmacy.
Keep a copy of your prescription handy, and compare the price of the brand name versus generic valacyclovir. The generic version is usually cheaper and works the same.
Bottom line: Valtrex is a powerful tool against herpes viruses when you use the right dose, stick to the schedule, and source it from a legitimate pharmacy. If you follow these basics, you’ll reduce outbreak severity, speed up healing, and keep side effects to a minimum.
