Valacyclovir is an antiviral pill doctors use to treat cold sores, shingles, and genital herpes. It works by stopping the virus from multiplying, which helps sores heal faster and reduces pain. If you’ve been told you might need it, you probably have a lot of questions about getting the medicine, how to take it, and what to watch out for.
First step is a doctor’s visit. Most doctors will ask about your symptoms, medical history, and any meds you’re already taking. If they think valacyclovir is right, they’ll write a script either on paper or electronically. In many places you can now get the prescription through a telehealth service – you fill out a short questionnaire, have a video call, and the doctor sends the script straight to a pharmacy.
Insurance can cover part of the cost, but coverage varies. Check your plan’s formulary to see if valacyclovir is listed. If it isn’t, ask the pharmacist about a generic version (the brand name is Valtrex). Generic valacyclovir works the same and is usually cheaper.
Typical dosing depends on the infection. For cold sores, adults often take 2 g once, then repeat after 12 hours if needed. Shingles treatment usually means 1 g three times daily for 7 days. Genital herpes outbreaks often require 1 g twice daily for 10 days. Always follow the exact schedule your doctor gives you – missing doses can let the virus bounce back.
Take the pill with a full glass of water. You can eat before or after it; food doesn’t change how the drug works. Stay hydrated, especially if you’re on higher doses, because the medicine is cleared through the kidneys.
Side effects are usually mild: headache, nausea, or stomach upset. If you notice a rash, severe stomach pain, or trouble breathing, call your doctor right away. People with kidney problems may need a lower dose, so be sure to tell your provider about any kidney issues.
Don’t mix valacyclovir with other antivirals unless your doctor says it’s okay. It’s also smart to avoid alcohol if you’re feeling nauseous, as it can make the stomach upset worse.
For those who travel or live far from a pharmacy, ask the doctor to send a longer prescription or to set up a mail‑order service. Many online pharmacies will verify the script and ship the medication directly to your door, often with tracking.
