Nytol Original contains a commonly used antihistamine called diphenhydramine hydrochloride. It works by blocking the normal actions of histamine, the chemical that stimulates arousal-promoting areas of the brain. This helps reduce alertness and promote that first drowsy stage of sleep, helping you to then drift off into a restful, deeper sleep. It provides temporary relief for sleeplessness by using a common antihistamine as a sedative to help you drift off quickly, sleep soundly and wake up refreshed. Usage One tablet to be taken at night.
