Take Valacyclovir exactly as prescribed by your healthcare provider. Your dose of Valacyclovir and length of treatment will depend on the type of herpes infection that you have and any other medical problems that you have. Do not stop valacyclovir or change your treatment without talking to your healthcare provider. Valacyclovir can be taken with or without food. You should start treatment as soon as possible after your symptoms start during episodic therapy. If you miss a dose of Valacyclovir take it as soon as you remember and then take your next dose at its regular time. However, if it is almost time for your next dose, do not take the missed dose. Wait and take the next dose at the regular time. Do not take more than the prescribed number of Valacyclovir each day.
