Valacyclovir - An Overview
Valacyclovir is an antiviral drug used to treat and suppress infections caused by herpes simplex virus (HSV-1 and HSV-2) and varicella-zoster virus. People who need treatment for cold sores, genital herpes or shingles can connect with a medical provider through Push Health who can prescribe valacyclovir medication when appropriate to do so.
What Is Valacyclovir Used For?
Valacyclovir prescription medication, marketed under the brand name Valtrex, is an antiviral medication used in various situations:
- Genital herpes: Episodic treatment of outbreaks and daily suppressive therapy.
- Cold sores (herpes labialis):
- Shingles (herpes zoster): Acute treatment
- Chickenpox: Selected patients (e.g., adults or those at higher risk of complications).
- Transmission reduction: Daily valacyclovir is FDA-approved to help reduce the risk of transmitting genital herpes to uninfected partners.
Valacyclovir belongs to a class of drugs known as nucleoside analogue DNA polymerase inhibitors. After oral administration, valacyclovir is rapidly converted to acyclovir (Zovirax) which inhibits viral DNA replication. Valacyclovir has a higher oral bioavailability than acyclovir which allows for less frequent dosing. Valacyclovir is similar to the medication famciclovir (previously Famvir).
Valacyclovir - Dosage & Cost
Valacyclovir is often prescribed using several regimens which are sometimes customized to the needs of individual patients based on the judgment of the prescribing medical provider:
- Cold sores: 2 g every 12 hours for 1 day (two doses)
- Genital herpes - episodic: 500 mg or 1 g twice daily for 3-10 days (depending on initial vs recurrent episode)
- Genital herpes - daily suppression: 500 mg once daily (or 1 g once daily for very frequent outbreaks)
- Shingles: 1 g three times daily for 7 days
Dose adjustment is often needed in people with kidney impairment. Staying well hydrated is also important while taking valacyclovir prescription medication.

Frequently Asked Questions about Valacyclovir
What is valacyclovir used for?
Valacyclovir is an antiviral medication used for the treatment of shingles and selected cases of chickenpox. It is also used for the treatment and suppression of genital herpes and cold sores and reduction of genital herpes transmission risk to partners.
Is valacyclovir the same as Valtrex?
Yes. Valtrex is the brand name for valacyclovir. Generic valacyclovir is considered bioequivalent, is more affordable, and is the form most pharmacies dispense.
What is the difference between valacyclovir and acyclovir?
Valacyclovir is converted to acyclovir in the body and has higher bioavailability which results in the need for fewer daily doses. Both are effective. Valacyclovir is usually more convenient while acyclovir is often more affordable.
How long does valacyclovir take to work?
Valacyclovir begins inhibiting viral replication within hours of the first dose. For genital herpes, symptom improvement is typically noticed within 2-3 days. Start treatment at the earliest sign of symptoms.
Can valacyclovir prevent herpes outbreaks?
Yes. Daily suppressive therapy with valacyclovir reduces the frequency of genital herpes outbreaks.
Can valacyclovir reduce the risk of transmitting herpes to a partner?
Yes. Valacyclovir is specifically FDA-approved to reduce (but not eliminate) the risk of transmitting genital herpes to uninfected heterosexual partners. Daily suppression should be combined with safe sex practices.
Is valacyclovir a controlled substance?
No. Valacyclovir requires a prescription but is not a DEA-scheduled controlled substance.
Can valacyclovir be taken daily long-term?
Yes. Long-term daily suppressive therapy with valacyclovir is well established and safe for most patients. Clinical trials have followed patients on daily valacyclovir for up to one year without significant safety concerns. Long-term suppressive therapy is commonly used by patients who have frequent outbreaks or who are in relationships where reducing transmission risk is a priority. Periodic reassessment with a provider is reasonable to evaluate whether continued suppression is appropriate.
How much does valacyclovir cost?
Generic valacyclovir is relatively affordable. Valacyclovir 500 mg tablets typically cost approximately 15-30 cents per tablet at most pharmacies and daily suppressive therapy (one 500 mg tablet per day) costs approximately $5-$15 per month.
Valacyclovir - Side Effects
Valacyclovir prescription medication can cause side effects such as headache, nausea and abdominal pain. These side effects are typically mild. Moe significant side effects include thrombotic thrombocytopenic purpura / hemolytic uremic syndrome (TTP/HUS), kidney failure, and adverse central nervous system events. Valacyclovir does not eliminate latent virus and transmission is always a consideration, especially during outbreaks. Dose adjustment is sometimes needed in the setting of kidney issues and adequate hydration is recommended while using the medication. People with a sensitivity to valacyclovir, acyclovir or similar antivirals in the past should not use the medication. Questions about side effects or other concerns should be discussed with one's medical provider.
