Abreva is an over-the-counter medication used to treat cold sores [1]. It is available for purchase at many retail locations, including drugstores and supermarkets.
Where Can I Buy Abreva?
You can typically find Abreva at major pharmacy chains such as CVS, Walgreens, and Rite Aid [1]. It is also commonly stocked in the personal care aisle of large retailers like Walmart and Target. Many grocery stores with a pharmacy section will also carry Abreva. Online retailers like Amazon are another option for purchasing the product.
How Does Abreva Work?
Abreva contains the active ingredient docosanol, which works by inhibiting the ability of the herpes simplex virus to enter healthy cells [1][2]. By blocking viral entry, it can help to shorten healing time and reduce symptoms of cold sores [1].
How Long Does Abreva Take to Work?
When applied at the first sign of a cold sore, Abreva can help shorten healing time [1]. For many users, this means healing can be achieved in as little as four days [1]. Consistent application as directed is important for optimal results.
Can Abreva Prevent Cold Sores?
Abreva is intended for the treatment of cold sores once they have appeared. It is not typically used for the prevention of cold sores.
What Are the Side Effects of Abreva?
Common side effects associated with Abreva include headache and application site reactions such as burning, itching, or stinging [3]. If you experience any severe or persistent side effects, it is advisable to discontinue use and consult a healthcare professional.
Are There Alternatives to Abreva?
Other over-the-counter treatments for cold sores are available, often containing different active ingredients like acyclovir or benzyl alcohol [4]. Prescription antiviral medications, such as acyclovir, valacyclovir, and famciclovir, are also used to treat cold sores and can be more effective for frequent or severe outbreaks [5].
What Causes Cold Sores?
Cold sores are caused by the herpes simplex virus (HSV-1) [6]. Once infected, the virus remains dormant in the body and can reactivate due to triggers such as stress, illness, sun exposure, or hormonal changes [6].
