Diphenhydramine HCl 25 mg is a first-generation antihistamine sold in a 100-tablet bottle. It is the same active ingredient as Benadryl, so it relieves allergy symptoms and also causes drowsiness, which makes it a common over-the-counter sleep aid. It works fast but lasts only about four to six hours and often leaves people groggy the next morning. It suits adults who want a cheap, familiar antihistamine for occasional allergies or short-term sleeplessness, not people who need a non-drowsy formula.
