What are cold sores?

Cold sores are small blisters around the mouth, caused by the herpes simplex virus. They are sometimes called fever blisters. The most common strain of the virus causing cold sores is herpes simplex virus 1. It can be spread by kissing or sharing eating utensils or even sharing towels. Herpes simplex is not curable, but may lie dormant for a long time. Episodes of the cold sores last no longer than 2 weeks. Hot sun, cold wind, a cold or other illness, or a weak immune system can cause an outbreak of herpes simplex virus.

Over-the-counter topical anesthetics or anti-inflammatory agents may help with symptoms

Cold sores take about 1 to 3 weeks to heal. The first time they appear, they can take up to 3 weeks to heal. But, when cold sores return, they usually take a week to heal if no medicines are used. Antiviral medications may help, but they need to be started before day 3 or 4 of the blister formation. Antivirals are usually not recommended for otherwise healthy people. Always consult your health care provider or dentist if the sore does not heal or becomes worse as time passes.

Can cold sores be prevented?

If you have never had a cold sore, avoid skin-to-skin contact with someone who has an active cold sore. If you have had a cold sore, you may prevent or reduce the number of recurrences by determining what triggers your outbreaks and avoiding the trigger. For instance, if sun exposure is a trigger, use sun screen when in the sun. If you have frequent outbreaks, consult with your health care provider. Starting treatment as soon as you know you are developing a cold sore can promote healing and reduce the time it takes a cold sore to heal.
