How does Abreva work on cold sores?
Abreva contains the active ingredient docosanol 10% [1]. Docosanol works by creating a barrier to help protect healthy cells from the herpes simplex virus (HSV-1), which causes cold sores [1]. By preventing the virus from penetrating healthy cells, it is believed to inhibit viral replication and spread [1].
How quickly does Abreva start working?
When used at the first sign of a cold sore, such as tingling, itching, or burning, Abreva can start healing within 2.1 days [1]. It is important to apply it as directed on the packaging for optimal results [1].
What are the side effects of Abreva?
Common side effects associated with Abreva include headache and application site reactions like redness, itching, or stinging [1]. These are typically mild [1].
Where can I buy Abreva and how much does it cost?
Abreva is available at most pharmacies, drug stores, and mass retailers [1]. The price can vary depending on the retailer and package size, but it typically ranges from $15 to $25 for a 2-gram tube [2].
Are there alternatives to Abreva for treating cold sores?
While Abreva is a topical treatment, other options exist for cold sore management. Prescription antiviral medications, such as acyclovir, valacyclovir, and famciclovir, can be taken orally or applied topically to help shorten healing time and reduce symptom severity [3]. Home remedies and other over-the-counter products may also offer some relief, though their efficacy can vary [4].
