What is Valtrex?

Valtrex and the generic alternative Valacyclovir is an antiviral drug which is used to treat infections caused by herpes virus such as genital herpes, cold sores and shingles. Valacyclovir slows the growth and spread of herpes which helps the body to fight the infection. However, these viruses will continue to live in the body between outbreaks. Valtrex decreases the severity and length of outbreaks but will not cure herpes or prevent you from spreading the infection to others. This medication may also be used to treat chickenpox in children and cold sores in those over 12.

Always read the patient information and instructions carefully before using this medication.

  • Take valacyclovir orally either with or without food.
  • Make sure to drink plenty of fluids while taking this medication.
  • Your valacyclovir dosage is based the type of infection, your medical condition, weight and response to treatment. Do not change or increase your Valtrex dosage unless advised by a doctor.
  • This medication is most effective when the amount of medicine in your body is kept at a constant level. Therefore you should take this medication at the same time each day.
  • Take this medication at the first sign of an outbreak and continue to take it until the full prescribed amount is finished.

  • If you have any drug allergies.
  • Which other prescription and non-prescription medications you currently take.
  • Your medical history especially of kidney problems.
  • If you use marijuana.
  • If you will be having any immunizations or vaccinations while using this medication.

  • Cold sores spread easily. During an outbreak, avoid close physical contact such as kissing until the cold sores have completely healed. Do not touch cold sores, and if you do, you’re your hands immediately.
