SINGLE dose of acyclovir (Zovirax) to ward off fever blisters or genital herpes
September 1996
Some physicians are having success by giving a big SINGLE dose of acyclovir (Zovirax) to ward off fever blisters or genital herpes.
The usual dose for intermittent therapy for genital herpes is 200 mg, 5 times a day, for 5 days.
Preliminary evidence shows that a single dose of 800 mg often works, if it's given soon enough. But it MUST be taken at the first sign of tingling, etc...to prevent blisters from forming.
