Valacyclovir (Valtrex) - An Overview

Valacyclovir is an antiviral drug that is indicated for the treatment of cold sores and genital herpes in adult patients. Push Health helps people who are in need of a valacyclovir prescription (Valtrex) connect with a medical provider to get the valacyclovir medication, when appropriate, that they need.

Valacyclovir - Administration and Use

Valacyclovir (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 is rapidly converted to acyclovir which has antiviral activity against HSV types 1 and 2 (HSV-1 and HSV-2 respectively) and VZV. Valacyclovir is similar to the medication famciclovir.

After oral administration, Valtrex is rapidly absorbed and is converted to acyclovir and L-valine in the intestines and/or the liver. Plasma concentrations of unconverted valacyclovir are low. The plasma elimination half-life of acyclovir (converted from valacyclovir) was 2.5 to 3.3 hours in volunteers with normal renal function.

Valacyclovir (Valtrex) - Dosage

Valacyclovir hydrochloride itself is a white to off-white powder. Valtrex caplets are oral caplets that contain valacyclovir hydrochloride equivalent to 500 mg or 1 gram of valacyclovir. These caplets also contain other inactive ingredients such as carnauba wax and silicon dioxide. Valtrex (valacyclovir) caplets are blue, film-coated caplets printed with edible white ink. For adults with cold sores, some regimens use a valacyclovir dosage of 2 grams every 12 hours for 1 day. For genital herpes, some regimens use valacyclovir dosing of 500 mg to 1 gram twice daily for up to 10 days. The final valacyclovir (Valtrex) dosing protocol is determined at the discretion of the prescribing medical provider. Valacyclovir (Valtrex) caplets should be stored at 15 ° to 25 ° C.
