Benadryl, a common over-the-counter medication, can be a lifesaver for those seeking relief from allergies, itching, or even motion sickness. However, like many drugs, it carries the risk of overdose when misused or taken in excessive amounts. This article aims to shed light on five critical aspects of Benadryl overdose, offering essential information for both healthcare professionals and the general public.
