I’m always looking for drug-free ways to prevent my allergies. Recently, I came across an ad on the internet for Chloraseptic’s “Allergen Block.” This product, advertised as a "drug-free” way to prevent allergies, is a clear topical gel containing petroleum, glycerin and other ingredients.

Allergen Block was created by a licensed engineer who used the scientific principal that oppositely charged particles tend to repel each other. The product is a positively-charged gel which supposedly blocks negatively-charged allergens on contact. You can find more information at https://www.allergenblock.com/product.html.

A children’s version of the product also is available. It’s called Little Allergies Allergen Block and is an identical gel in a different package.

I questioned whether it was possible to repel allergens with a gel. But maybe the developer of the product was right and allergens are negatively charged. Or maybe the product was simply petroleum mixed with glycerin. There was only one way to find out---try it!

The allergen block is applied externally around the nostrils. You put a small amount of the gel on your forefinger and spread the gel between your forefinger and thumb. Then, apply a thin film of gel around your nostrils and between your nose and upper lip. Next, you rub it in until dry to the touch. The gel is supposed to last 4-6 hours unless your nose and face become wet.

I didn’t expect the gel to prevent all my allergy symptoms. I was only hoping for a little extra relief. I believe that’s what I achieved but I have no scientific data to back this up. I spend a lot of time outdoors around many trees and other pollinating vegetation and this product seems to help a bit.

The gel isn't considered to be a medication. The Food and Drug Administration has officially approved it as a "device." The FDA approval process for devices is much less rigorous than it is for drugs. Prestige Brands didn't have to prove that the Allergen Block is effective. It merely had to make a case that it was "substantially equivalent" to other products already on the market.

A 0.1 ounce tube of either type of Allergen Block costs about $14. When used as directed, each tube is enough for about 150 applications.

The Allergen Block website claims that the gel protects against ragweed, pollen, dust mites, pet dander and house dust. It also claims that it helps prevent sneezing, nasal congestion, itchy nose and runny nose. The bottom line is you probably need to try this product to see for yourself.
