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.

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.
