Aciclovir tablets come in various strengths, 200mg, 400mg, and 800mg. Different strengths and different lengths of courses are recommended to treat different types of herpes virus infections. Cold sores are generally caused by herpes simplex virus type 1 (HSV1). A 5-day course of 200mg strength tablets taken 5 times a day is the recommended course of treatment of a cold sore outbreak.

All have the same active ingredient. The shelf life of the medication is up to 3 years, which means that people who are prone to cold sores can keep a stand-by supply at home for use when needed.
