Acyclovir: Orally, Acyclovir is usually taken every four hours, with dosages of 200 mg to 800 mg. The longer duration of action for valacyclovir means that it is only taken every eight hours, with a 1, 000 mg dosage each time. The active portion of these agents is the same, the differences are in rate of absorption and duration of efficacy.
