Diphenhydramine hydrochloride, commonly known as Benadryl, is an antihistamine that can cause drowsiness as a side effect. Many people use it as a sleep aid to help them fall asleep. However, it's important to note that while it may help with falling asleep, it can also lead to grogginess and drowsiness the next day.
