Valtrex is a commonly prescribed antiviral for cold sores, genital herpes, and shingles. If you get outbreaks, starting Valtrex early often shortens their length and reduces pain. That early start really matters — take it as soon as you feel the first tingle or see a sore.
Doctors use Valtrex in a few ways: to treat a sudden outbreak (episodic therapy), to prevent recurring outbreaks (suppressive therapy), and to treat shingles. Typical examples: for a cold sore many providers recommend a single-day, higher-dose regimen taken right when symptoms start; for genital herpes an episodic course is often 1 gram twice daily for 5 days; for daily suppression doses are usually 500 mg to 1 g once daily depending on how often outbreaks occur. For shingles the common dose is 1 g three times daily for 7 days. Always follow your prescriber's exact instructions — these are examples, not a substitute for medical advice.
Keep in mind timing and hydration. Drink water with each dose and finish the full course. Starting treatment within the first 24–48 hours of symptoms gives the best results for most people.
Most people tolerate Valtrex well. Common side effects include headache, nausea, and stomach upset. Less commonly, people — especially older adults or those with kidney problems — can get confusion or kidney issues. If you have reduced kidney function, your provider will adjust the dose. Mention other medications like probenecid or kidney-affecting drugs when you talk to your prescriber.
Valtrex is prescription-only. Don’t buy from sites that skip a doctor’s review. If you prefer ordering online, choose a licensed Canadian or international pharmacy that asks for a valid prescription, shows contact info, and has verified reviews. Canadian Pharmacy 24 recommends checking pharmacy licenses and looking for secure checkout and clear return policies.
Pregnancy and breastfeeding decisions should be made with your doctor. Antivirals are sometimes used when the benefits outweigh risks, but you need a personalized plan. Also, antiviral resistance is rare in healthy people but can happen in those with weak immune systems.
Quick practical checklist: start treatment early, drink water, follow dosing instructions, tell your doctor about kidney disease or other meds, and buy Valtrex only from reputable pharmacies that require a prescription. If you notice severe side effects — high fever, severe confusion, rash, or trouble urinating — get medical help right away.
