VALTREX Uses, Side Effects, Interactions, Warnings & Dosing
What is VALTREX?
VALTREX is the brand name for valacyclovir and is available as an oral tablet.
What dosages is VALTREX available in?
VALTREX is available as 500 mg and 1000 mg oral tablet.
What is VALTREX used for?
VALTREX is an antiviral that is used to treat:
Chickenpox (varicella) in children ages 2 to 17 years old
Cold sores in people age 12 years and older
Genital herpes in adults
Shingles (herpes zoster) in adults
How does VALTREX work?
VALTREX is an antiviral medication. When VALTREX gets absorbed into your body, it gets converted (changed) to acyclovir, another available antiviral medication.
VALTREX works by preventing an important protein that’s used to make genetic material (DNA) from working in the herpes simplex virus and varicella zoster virus. By doing this, VALTREX prevents the virus from making copies of itself and spreading.
How do I take VALTREX?
VALTREX is dosed as follows:
Cold sores
The typical dose is 2 grams by mouth twice daily (taken 12 hours apart) for 1 day.
Genital herpes
First outbreak: The typical dose is 1 gram by mouth twice daily for 10 days.
Repeated outbreaks: The typical dose is 500 mg by mouth twice daily for 3 days.
Outbreak prevention: The typical dosing range is 500 mg to 1 gram by mouth once daily, depending on the number of outbreaks you’ve had. For people who also have human immunodeficiency virus (HIV), the typical dose is 500 mg twice daily.
Lower risk of transmission: The typical dose is 500 mg by mouth once daily.
Shingles
The typical dose is 1 gram by mouth 3 times daily for 7 days.
Chickenpox
Your child’s provider will determine their dose of VALTREX based on your child’s body weight. The typical dose is 20 mg/kg by mouth 3 times daily for 5 days. The maximum recommended dose is 1 gram.
Your dose might differ if you have kidney problems.
Is it safe for me to take VALTREX?

You should always discuss potential side effects with your physician to ensure the medication is suitable and right for you. You should not use this medication if you have a hypersensitivity to valacyclovir (e.g., anaphylaxis), acyclovir, or any
