How Does Sitavig Work?
Sitavig delivers concentrated medication that stays localized at the site of viral replication in the mouth. Patients treated with a single dose of Sitavig went an average of 304 days before their next cold sore outbreak compared with an average of 199 days for patients treated with a placebo.¹*
Patients also experienced significant relief from cold sore symptoms in just 3.5 days and completely healed in 5.5 days, when Sitavig was applied within 1 hour of feeling the sensation and before the blister appeared.¹*
Even if you have no signs of a cold sore, it’s smart to see your healthcare provider and ask for Sitavig. Go ahead and get your Sitavig prescription filled and keep your Sitavig tablet with you at all times.
