Nytol Original is used to relieve temporary sleeping
difficulties. The active ingredient is diphenhydramine
hydrochloride, an antihistamine that causes
sleepiness or drowsiness. Temporary difficulties in
getting a good night’s sleep can be caused by various
problems such as stress, jet lag or personal problems
such as bereavement. In sleep problems of this type,
Nytol Original has been shown to help sufferers to
fall asleep faster, have a longer and deeper sleep,
and to wake up feeling rested in the morning.
