How Does Abreva Work?
Abreva works by penetrating deep below the skin's surface to help heal the cold sore [3]. Docosanol is believed to work by blocking the entry of the herpes simplex virus (HSV-1) into skin cells, thereby preventing the virus from multiplying and spreading [3]. By inhibiting viral entry, Abreva aims to shorten the healing time and reduce the duration of cold sore symptoms [3].
What Are the Symptoms Abreva Treats?
Abreva is indicated for the treatment of cold sores and their symptoms, including tingling, itching, burning, and pain [1]. Cold sores are caused by the herpes simplex virus and typically appear as small blisters on or around the lips [4].
How Long Does Abreva Take to Work?
When used as directed, Abreva can shorten the healing time of a cold sore [3]. Clinical studies have shown that Abreva can help heal cold sores in as little as four days when treatment is started at the first sign of a cold sore [3].
Where Can I Buy Abreva?
Abreva is widely available at most pharmacies, drug stores, and supermarkets in the United States [2]. It is also often available through online retailers [2].
Are There Any Alternatives to Abreva?
Other OTC treatments for cold sores are available, which may contain different active ingredients or work through different mechanisms [5]. Prescription antiviral medications are also available for more severe or frequent outbreaks [5]. For individuals experiencing recurrent or severe cold sores, consulting a healthcare professional is recommended to discuss treatment options [5].
