What is the Difference Between Abreva and Other Cold Sore Treatments?
Abreva is an over-the-counter topical cream that contains docosanol as its active ingredient [1]. Unlike some other cold sore treatments that may focus on pain relief or symptom management, Abreva's active ingredient directly targets the virus's ability to spread [2].
