Nytol One-A-Night Tablets Nytol One-A-Night Tablets are a clinically proven night time sleep aid, to relieve temporary sleeplessness & lull you into your regular sleep pattern. They contain diphenhydramine hydrochloride, an antihistamine that blocks the normal actions of histamine
- the chemical that stimulates arousal-promoting areas of the brain. This helps to reduce alertness & promote that first drowsy stage of sleep, making it easier to drift off naturally into restful deeper sleep. Nytol One-A-Night Tablets have been shown to help those suffering from sleep problems caused by jet lag, stress & personal problems such as bereavement to fall asleep faster, have a longer, deeper sleep & to wake up feeling rested in the morning. Nytol One-A-Night Tablets are suitable for adults & children over 16 years of age.
