Benadryl

Benadryl is an over-the-counter medication containing diphenhydramine, an antihistamine that helps alleviate allergy symptoms such as sneezing, runny nose, itchy eyes, and skin reactions. It works by blocking the effects of histamine, a substance involved in allergic responses. Additionally, Benadryl can be used to prevent or treat motion sickness and to induce sleep. While effective, it may cause drowsiness and other side effects, so it’s important to follow dosing instructions. It’s generally safe for short-term use but should be used with caution in certain populations, like older adults or those with specific health conditions.
