Millions get a cold sore at least once in their life, and some get them frequently throughout the year. They are no fun at all to deal with, causing both pain and embarrassment. Benzalkonium chloride for cold sores is an increasingly popular treatment.

If you’ve had cold sores before, you’ll know how to identify the first signs. The tell-tale tingling sensation on your lip.  If you get treatment as soon as you feel this sensation, you will be able to avoid the worst symptoms. The key to finding a remedy that works is to look at the active ingredients. The active ingredient in any treatment is the one that will have the most significant impact.

Although the most common place to find a cold sore is on the lip, they can also appear on other parts of the face, such as under the nose or on the cheek, and the chin.

Fever blisters, as they are also called, go through different stages.  First is the tingling sensation, followed by the lump.  Then comes the fluid-filled blister, which can be very painful.  After that, the fluid dries up and leaves a scab in that spot.  This scab can be very itchy, and it can easily crack and let some liquid out in the process.

It is essential to keep this scab moisturized to lessen the chances of this happening.  After the scab comes off, you will probably have a noticeable spot left, but this will fade.  The average life of a fever blister is about 10 to 14 days, and this is why using a treatment from the start is imperative.

In this article, we will be talking more about Benzalkonium Chloride.  We will explain how it works and tell you about treatments that contain it.

When Not to Use Benzalkonium Chloride

There are a few people that should not use this in any treatment. These include pregnant women or women who are breastfeeding. Also, it should not be used in children.
