What It's For & How To Take
Valacyclovir is used to treat infections caused by the herpes simplex or the herpes zoster virus. The herpes simplex virus presents as cold sores around your mouth, genitals, or sometimes other areas of your body such as your hands or eyes. The herpes zoster virus presents as either chickenpox or shingles.
Valacyclovir is used to decrease the severity and duration of a virus outbreak. This medication is not a cure for herpes. These viruses live in our body. The moment our immune system is weakened, either through stress, sickness or some other reason, the virus will grow and manifest as an outbreak.
This medication will help sores heal faster, keeps new sores from forming and may help reduce how long the pain or itching will last. Valacyclovir may also help prevent a herpes outbreak from spreading to another part of the body in a patient with a weak immune system.
This medication is also used to suppress outbreaks in people who have had recurrent infections. When used to suppress outbreaks, valacyclovir is taken in a smaller dose on a regular daily schedule.
Your dose is based on your specific type of outbreak or suppression treatment. This medication is usually prescribed to be taken anywhere from 1-3 times daily, with or without food. Take your dose at evenly spaced intervals. The medication works best when a constant level is maintained in the body. Drink a full glass of water with each dose of valacyclovir, unless your doctor has instructed you not to.
Valacyclovir works best when started at the first sign of an outbreak. Finish your cycle of medication unless directed by your physician to do otherwise. If your condition does not improve or worsens, notify your doctor.
If you miss a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
