How does Single-Day FAMVIR work?
When you first start feeling the symptoms of an outbreak, the virus is already actively reproducing and the medicine enters cells infected with the herpes virus and stops the virus from multiplying. Starting Single-Day FAMVIR at this critical time can stop the virus from reproducing. If you can stop the virus during this time, you may be able to stop a full-blown outbreak. 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.
