Docosanol

Drug Details

Docosanol, commonly known as Abreva, is an over-the-counter cream designed to treat cold sores, also referred to as fever blisters, on the face or lips. This antiviral cream is most effective when applied five times daily at the onset of cold sore symptoms, such as tingling, pain, burning, and itching. Docosanol works by preventing the herpes simplex virus, which causes cold sores, from entering healthy skin cells and replicating. While it helps speed up the healing process and reduce symptoms, it is important to note that docosanol does not cure herpes, prevent future outbreaks, or stop the transmission of the virus to others. It is not intended for treating canker sores, shingles, or genital herpes. Side effects are rare, but some users may experience mild stinging. Always consult a healthcare professional before starting any new medication.
