Chewing ANY Benadryl does the same. The non-chewable tastes NASTY, but I know it works because it quickly numbs your mouth - the surface blood vessels under the tongue carry it quickly into the bloodstream.

I used this with my Mom one time after she deliberately ate pineapple upside down cake "because it looked so good" at her assisted living facility, and avoided a trip to the ER. Another time, after a bee sting, I used the trick and managed to avoid another Epi injection. Last year my Texas neighbor with a bee allergy got swarmed when he was mowing, we made him chew 2 Benadryl, I handed him an Epi Pen that he never had to use, and the ER doc complimented him and his wife on the excellent triage - he only needed one shot of epinephrine before they sent him home.

I love to avoid epinephrine when I can because it gives me a fierce headache.
