Nexcare Cold Sore Treatment

nexcareWhat is Nexcare Cold Sore Treatment?

Nexcare is an over-the-counter ointment for the topical treatment of cold sores. No prescription is necessary and Nexcare can be purchased at a number of retail outlets. The ointment contains the active ingredients benzocaine, allantoin, vitamin E and tea tree oil which are meant to be applied directly to a cold sore.

How Does It Work?

Benzocaine, the main ingredient in Nexcare, interferes with the actions of sodium in your nerve cells in a localized area. It works much the same way Novocain would or a topical treatment for tooth sensitivity.  Allantoin, the other main ingredient in Nexcare, is a substance that helps protect your skin and keep it moist. The vitamin E and tea tree oil essentially perform the same function as the Allantoin.

Does It Work?

It is well documented that the ingredients in Nexcare are effective remedies for the pain and discomfort associated with cold sores; however, there is no real evidence its ingredients have any properties that would actually affect the HSV-2 virus that causes the cold sore. 3M recommends you apply the cream up to four times a day and claim you should see results within the week. If symptoms do not improve, you should contact a doctor.

Downside

Nexcare is an effective treatment for the symptoms of HSV-2 but contains no virus fighting agents. There is no cure for the virus that causes cold sores to appear, but there are a number of things you can do to kill that virus as it flares up in your system. Nexcare does not help your body boost its immunity to viruses or directly affect the virus beyond alleviating the symptoms and limiting the spread of the sore.  Also, 3M does not list specific side effects but both benzocaine and tea tree oil has been known to cause skin irritation.

Upside

You know exactly what you are getting with Nexcare and 3M makes no claims beyond that. This is a topical cream meant to alleviate the pain and inflammation associated with a cold sore. The ingredients have been proven over the past hundred years to accomplish both those tasks and there is nothing extra added that does not help perform one of those two functions.

3M is one of the most trusted names in the consumer products market. Unlike some of the unknown names behind most herbal remedies, 3M is one of the most reputable companies in the world. Some people take comfort in the reputation of an established company that has a proven track record of manufacturing effective products.

Bottom Line

There isn’t much that can be said about this product. It is a simple topical cream with ingredients you can find in dozens of similar products. The price will vary widely depending on where it is purchased so I would use that as the determining factor when choosing a cold sore remedy. You can also look for generic compounds with similar dosages if price is an issue.
