What is valacyclovir (Valtrex) used for?
Valacyclovir is an antiviral used to treat herpes virus infections in people with a healthy immune system. In adults it is FDA-approved for cold sores (herpes labialis), genital herpes (first-time and recurrent outbreaks, plus daily suppression to reduce outbreaks and lower transmission risk with safer-sex practices), and shingles (herpes zoster). In children ages 2 to under 18 it is approved to treat chickenpox. It controls these infections but does not cure herpes.
How quickly does valacyclovir start working for a cold sore or genital herpes outbreak?
Valacyclovir works best when started as early as possible, ideally at the very first signs of an outbreak such as tingling, itching, or burning. Once absorbed, the body converts it to acyclovir, which begins acting against the virus to help sores heal faster and ease symptoms. Follow your provider's directions on when to start and how long to take it, and start treatment as soon as symptoms appear rather than waiting.
Is valacyclovir the same as Valtrex, and is there a generic version?
Valacyclovir is the generic name, and Valtrex is the brand name for the same medicine, so yes, a generic version is available. The generic contains the same active ingredient, valacyclovir hydrochloride, and works the same way, but it typically costs much less than the brand. You can compare prices for both on Rx.com.
Can you take valacyclovir every day to prevent herpes outbreaks?
Yes. For genital herpes, valacyclovir is FDA-approved for daily suppressive therapy to reduce how often outbreaks happen and, combined with safer-sex practices, to lower the risk of passing the virus to a partner. Your provider will decide whether daily suppression is right for you and set the correct dose based on your health, including any kidney concerns.
What are the most common side effects of valacyclovir?
The most common side effects are usually mild and can include headache, nausea, and stomach upset. Staying well hydrated is important. Less common but more serious risks include kidney problems and nervous-system effects such as confusion, especially in older adults, people with kidney impairment, or those who are dehydrated. Contact your provider if you notice unusual bruising or bleeding, a big drop in urination, confusion, or other worrying symptoms.

What is valacyclovir and how does it work?

Valacyclovir is an antiviral medicine and the generic form of the brand-name drug Valtrex. It is a prodrug, which means the body converts it into acyclovir after you take it. Acyclovir works by blocking an enzyme (DNA polymerase) that the herpes virus needs to copy itself, which helps slow the spread of the virus and speed healing.

It is FDA-approved to treat several herpes virus infections in people with a healthy immune system: cold sores (herpes labialis), genital herpes (both first-time and recurrent outbreaks, and daily suppression to reduce how often outbreaks happen and to lower the risk of passing herpes to a partner when combined with safer-sex practices), and shingles (herpes zoster) in adults. It is also approved to treat chickenpox (varicella) in children ages 2 to under 18. Valacyclovir controls these infections but is not a cure for herpes.

How much does valacyclovir cost without insurance?

Valacyclovir is available as a generic, so it is generally much less expensive than brand-name Valtrex. Even so, the cash price without insurance can differ a lot depending on which pharmacy you use, which is exactly why comparing prices is worth the few seconds it takes. A coupon can help whether or not you have insurance, since the coupon price is sometimes lower than an insurance copay.

Rx.com compares live valacyclovir prices at more than 60,000 pharmacies so you do not have to call around. Enter your ZIP above to see today's price at pharmacies near you, then bring the free Rx.com coupon to the counter. Prices are shown live on this page because they change frequently.

Valacyclovir alternatives and related medicines

Valacyclovir belongs to a family of antiviral medicines used for herpes infections. If you are comparing options, these related drugs are commonly prescribed:

  • Valtrex — the brand-name version of valacyclovir.
  • Acyclovir — the older oral antiviral that valacyclovir is converted into; it usually requires more frequent dosing.
  • Acyclovir cream — a topical option often used for cold sores.
  • Famciclovir — another oral antiviral prodrug used for similar herpes infections.

Which medicine is right for you depends on the type of infection and your health history. Your provider or pharmacist can help you choose, and you can compare prices for each on Rx.com.

Safety and side effects

Valacyclovir has no boxed warning, and most people tolerate it well. The most common side effects are generally mild, such as headache, nausea, and stomach upset. It is important to stay well hydrated while taking it. This information is not a substitute for medical advice; talk with your provider or pharmacist about your specific situation.

Some people need extra caution. Acute kidney problems can occur, especially in older adults, in people with existing kidney impairment, or when dehydrated or taking other drugs that affect the kidneys, so the dose is reduced in kidney impairment. Nervous-system effects such as confusion, hallucinations, agitation, or seizures can occur, particularly in older adults and those with kidney impairment. A rare but serious blood disorder (thrombotic thrombocytopenic purpura/hemolytic uremic syndrome, TTP/HUS), which can be fatal, has been reported at high doses in people who are severely immunocompromised, such as those with advanced HIV or bone-marrow or kidney transplants. Tell your provider about all your health conditions and medicines before starting valacyclovir, and seek care promptly if you have unusual bruising, bleeding, or a large drop in urination.
