diphenhydramine hydrochloride is an antihistamine drug having the chemical name 2-(diphenylmethoxy)-n,n -dimethylethylamine hydrochloride and has the molecular formula c17h21no•hci (molecular weight 291.82). it occurs as a white odorless, crystalline powder and is freely soluble in water and alcohol.

diphenhydramine hydrochloride is an antihistamine with anticholinergic (drying) and sedative effects. antihistamines appear to compete with histamine for cell receptor sites on effector cells.

a single oral dose of diphenhydramine hydrochloride is quickly absorbed with maximum activity occurring in approximately one hour. the duration of activity following an average dose of diphenhydramine hydrochloride is from four to six hours. diphenhydramine is widely distributed throughout the body, including the cns. little, if any, is excreted unchanged in the urine; most appears as the degradation products of metabolic transformation in the liver, which are almost completely excreted within 24 hours.

warnings
antihistamines should be used with considerable caution in patients with narrow-angle glaucoma, stenosing peptic ulcer, pyloroduodenal obstruction, symptomatic prostatic hypertrophy, or bladder-neck obstruction.

how should i take diphenhydramine

use diphenhydramine exactly as directed on the label, or as prescribed by your doctor. do not use in larger or smaller amounts or for longer than recommended. cold or allergy medicine is usually taken only for a short time until your symptoms clear up.

do not give diphenhydramine to a child younger than 2 years old. always ask a doctor before giving a cough or cold medicine to a child. death can occur from the misuse of cough and cold medicines in very young children.
