1. What Nytol is and what it is used for
Nytol 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 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.
Do not take Nytol for more than 2 weeks without consulting your doctor.
