Diphenhydramine, the active ingredient in the branded drug Benadryl, is an antihistamine that blocks the activity of histamine and reduces symptoms such as runny nose, watery eyes, and itching.
Diphenhydramine also causes drowsiness and slows down the part of the brain that controls nausea.
For these reasons, Benadryl may also be used to relieve occasional insomnia or prevent motion sickness. nine0005
For patients over 12 years of age, the standard dosage of Benadryl Allergy is 25 to 50 mg (milligrams) - one to two tablets or capsules - every four to six hours. Children aged 6 to 11 years can be given Benadryl at a maximum dose of 25 mg (one tablet or capsule) every four to six hours. Benadryl can be taken with or without food.
