Valtrex (valacyclovir) is one of the most common antiviral pills used to treat herpes simplex and shingles. In 2025, people still use it for cold sores, genital herpes outbreaks, and herpes zoster. The drug works best when you start it early, but long-term daily use as suppression therapy is common for people with frequent outbreaks.
Valacyclovir turns into acyclovir in the body and stops viruses from multiplying. For cold sores, take treatment at the very first tingle or blister. For genital herpes outbreaks, a typical dose is 1 gram twice daily for 7 to 10 days, though your doctor may change that. For shingles, higher doses and longer courses are used. If you have frequent recurrences, daily suppression doses — often 500 mg to 1 gram once daily — can cut outbreaks and reduce transmission risk.
Most people tolerate Valtrex well. Common side effects include headache, nausea, and stomach upset. Rarely, it can affect kidney function, especially in older adults or people with dehydration. Drink water while taking it and tell your doctor if you have kidney disease. If you’re pregnant or breastfeeding, talk to your provider — some may still recommend it when benefits outweigh risks.
In 2025 the market has many generic valacyclovir options. Generics cost less and generally match brand quality, but check pharmacy reviews and prescription requirements. Buying online is okay if the site is verified, shows a licensed pharmacy, and asks for a prescription. Avoid sites that sell controlled meds without a script or offer suspiciously low prices.
Keep pills in a cool, dry place. If you miss a dose of suppression therapy, take it as soon as you remember unless it’s almost time for the next dose; don’t double up. Start treatment fast during an outbreak — early treatment shortens symptoms. Use condoms and avoid intimate contact during active genital outbreaks to lower transmission chances.
When to Call a Doctor: Seek help if you have severe symptoms, fever, confused thinking, or if blisters spread to the eyes. Also see a doctor if you suspect drug interactions — Valtrex can interact with some chemotherapy drugs and medicines that affect kidney function.
If cost is an issue, compare prices, ask for generics, and check discount cards or pharmacy coupons — many plans cover valacyclovir for outbreaks and suppression. Telehealth services can prescribe Valtrex after a short consultation, but make sure they link to a licensed pharmacy. Keep a list of all medicines and supplements you take when you talk to your clinician to avoid interactions. If symptoms don’t improve after treatment, your doctor may test for resistance or consider alternative antivirals. Honest communication with your provider makes treatment safer and more effective. Stay informed.
