Whats the difference between “single-day” and “once daily”?
“Once daily” is a way of describing a suppressive treatment, which means a treatment you take every day. “Single-day” means you take the full course of treatment in one day. Only Single-Day FAMVIR can stop or shorten an outbreak with a single day of treatment. Take at the first sign or symptom. The effectiveness of FAMVIR has not been established when treatment is started more than 6 hours after the onset of symptoms or lesions.
