Can you treat cold sores with over-the-counter medicines?
Oral herpes, or as they're more widely known, cold sores are a common infection of the mouth area caused by herpes simplex virus type 1 (HSV-1). While there is no actual cure for cold sores, many over-the-counter treatments can shorten symptoms and help them heal faster. Cold sores are so common that most people in the United States are infected with HSV-1 by the age 20. After the initial infection, the virus isn't cured, but becomes dormant and goes to sleep in the face's nerve tissues. Sometimes, the virus later reactivates, or "wakes up" causing cold sores. The herpes virus is highly contagious and easily spreads from person-to-person. You can catch HSV-1 if you have personal or intimate contact with an infected person. You can also catch is if you simply come in contact with everyday items infected with the herpes virus such as dishes, towels, razors and other shared items. Parents can also spread the virus to their children during typical daily activities.
