The FDA is warning consumers not to swallow Benadryl Extra Strength Itch Stopping Gel. The gel is designed for topical use on skin. Despite the gel's goopy consistency and squeeze bottle, it appears that multiple consumers have taken it by mouth and been poisoned by the active ingredient, diphenhydramine.
The problem seems to be that the Benadryl brand is also used on liquid allergy products meant to be swallowed, confusing a few consumers.
Perhaps the use of the word "dummy" on the product?
