How do I switch from another Genital herpes treatment to valacyclovir 500 mg?

Do not replace your current antiviral tablet for tablet with valacyclovir. Different medicines have different doses and schedules. A licensed physician in your state must review your health information and decide whether switching is appropriate. Your new prescription label should explain exactly how to take the medicine.

Share the name and dose of your current treatment, when you last took it, and whether you use it daily or only during outbreaks. Explain why you want to switch, such as side effects, cost, or trouble following the schedule. Also report kidney problems, pregnancy or breastfeeding, allergies, and any past reaction to acyclovir or valacyclovir.

Ask when to stop the old medicine and when to start the new one. Do not overlap treatments or use leftover tablets to fill gaps unless your physician tells you to. Switching does not guarantee better outbreak control or fewer side effects. Results vary. If symptoms continue despite taking treatment as directed, your physician may need to reassess the diagnosis or arrange further care.
