What Is Valacyclovir Used For?
Valacyclovir prescription medication, marketed under the brand name Valtrex, belongs to a class of medications known as nucleoside analogue DNA polymerase inhibitors. Valacyclovir is indicated for the treatment of adult cold sores (herpes labialis) and genital herpes in immunocompetent patient and for reduction of transmission. After administration, valacyclovir hydrochloride medication is rapidly converted to acyclovir which has antiviral activity against HSV types 1 and 2 (HSV-1 and HSV-2 respectively) and VZV. After oral administration, valacyclovir is rapidly absorbed and is converted to acyclovir (Zovirax) and L-valine in the intestines and/or the liver. Plasma concentrations of unconverted valacyclovir are low. The plasma elimination half-life of was approximately 2.5 to 3.3 hours in volunteers with normal renal function. Valacyclovir is similar to the medication famciclovir (previously Famvir).

For adults with cold sores, some regimens use a valacyclovir dosage of 2 grams every 12 hours for 1 day, depending on the experience and judgment of the prescribing medical provider. For genital herpes, some regimens use valacyclovir dosing of 500 mg to 1 gram twice daily for up to 10 days. The final valacyclovir dosing protocol is determined at the discretion of the prescribing medical provider. Valacyclovir medication generally costs less than $1 per tablet at many pharmacies.

Frequently Asked Questions about Valacyclovir
What is valacyclovir used for?
Valacyclovir is an antiviral medication used to treat and prevent infections caused by herpes simplex virus (HSV-1 and HSV-2) and varicella-zoster virus. Primary indications include genital herpes (episodic treatment and daily suppression), cold sores, shingles, chickenpox in selected patients, and reduction of genital herpes transmission to partners.
Is valacyclovir the same as Valtrex?
Yes. Valtrex is the brand name for valacyclovir. Generic valacyclovir is bioequivalent to branded Valtrex and is significantly more affordable. Most pharmacies dispense generic valacyclovir in place of branded Valtrex.
What is the difference between valacyclovir and acyclovir?
Both valacyclovir and acyclovir work through the same active compound - valacyclovir is converted to acyclovir in the body. The key difference is bioavailability: valacyclovir achieves approximately 55% oral bioavailability vs. approximately 20% for acyclovir. This higher bioavailability allows for simpler, less frequent dosing - once or twice daily for most indications with valacyclovir vs. three to five times daily with acyclovir. For most patients, valacyclovir's more convenient dosing makes it the preferred option. Acyclovir remains appropriate when cost is a priority, as it is generally slightly less expensive per tablet.
How long does valacyclovir take to work?
Valacyclovir begins inhibiting viral replication within hours of the first dose. For genital herpes outbreaks, symptom improvement is typically noticed within 2-3 days, with most lesions healing within 3-10 days depending on the severity of the outbreak. Starting treatment at the earliest sign of symptoms - tingling or burning before lesions appear - produces the best outcomes. For shingles, starting within 72 hours of rash onset is critical for optimal benefit.
Can valacyclovir prevent herpes outbreaks?
Yes. Daily suppressive therapy with valacyclovir significantly reduces the frequency of genital herpes outbreaks - typically by 70–80% compared to no treatment in clinical trials. Daily suppression also reduces viral shedding between outbreaks, which reduces (but does not eliminate) the risk of transmitting the virus to partners. Valacyclovir 500 mg once daily is the standard suppressive dose for most patients; 1000 mg once daily is used for patients with very frequent outbreaks.
Can valacyclovir reduce the risk of transmitting herpes to a partner?
Yes. Valacyclovir 500 mg once daily is specifically FDA-approved to reduce the risk of transmitting genital herpes to uninfected heterosexual partners. In clinical trials, daily valacyclovir combined with safer sex practices reduced transmission risk by approximately 50% compared to placebo plus safer sex practices. Daily suppression does not eliminate transmission risk and should be combined with condom use.
Is valacyclovir a controlled substance?
No. Valacyclovir is not a DEA-scheduled controlled substance. It is a prescription-only medication but can be legally prescribed through a telehealth consultation when clinically appropriate.
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 moderately affordable. Valacyclovir 500 mg tablets typically cost approximately 15-30 cents per tablet at most pharmacies. Daily suppressive therapy (one 500 mg tablet per day) costs approximately $5-$15 per month. A standard 3-day episodic treatment course (six 500 mg tablets) typically costs $3-$6. Prescription savings cards can reduce costs further.
Valacyclovir - Side Effects
Valacyclovir prescription medication can cause side effects and anyone who has had a previous hypersensitivity or allergy to valacyclovir or similar drugs should avoid using the medication. More common side effects of taking valacyclovir drug are headache, nausea and abdominal pain.
