Fewer Recurrences. More Freedom.

Cold sores are a sore subject for many, which is why new Sitavig (acyclovir), 50mg Muco-Adhesive Buccal Tablet is such a breakthrough in the world of prescription cold sore treatment. Sitavig is a single-dose, prescription-strength treatment that may stop cold sores before they start, which means fewer outbreaks and a lot more freedom.¹

Sitavig works by delivering a concentrated dose of prescription cold sore medication that stays localized at the site of viral replication in the mouth. In clinical trials, patients who applied prescription Sitavig within one hour of the first sign of an outbreak experienced significant relief from their cold sore symptoms in just 3.5 days — and completely healed within 5.5 days.1 Plus, on average, patients treated with Sitavig went 105 days longer between cold sore outbreaks compared to patients treated with a placebo.1

The freedom to live your life — with fewer cold sores.¹
