What BENADRYL Original is used for

BENADRYL Original contains medicines called diphenhydramine and ammonium chloride.
Diphenhydramine belongs to a group of medicines called 'antihistamines'. Diphenhydramine helps to reduce common cold symptoms, such as runny nose, sneezing and watery eyes. Diphenhydramine also helps suppress dry, raspy coughs by its action in the brain. Ammonium chloride is an expectorant.
