Sleep

These tablets contain promethazine, an antihistamine that causes drowsiness. They're for short-term use when sleep is temporarily disrupted, for example after travel or during a stressful time. Check the leaflet for how many nights you can take them.

Good sleep habits help most people: a regular bedtime, less caffeine and fewer screens in the evening, and a cool, dark bedroom. See a GP if you've had trouble sleeping for several weeks or it's affecting your daily life.
