Sominex Tablets Pack of 16
How does it work?
Sominex tablets contain the active ingredient promethazine, which is a type of medicine called a sedating antihistamine.
Promethazine enters the brain in significant quantities and causes drowsiness. It decreases the time taken to fall asleep and increases the depth of sleep. This makes it helpful for the temporary relief of sleeping difficulties, for example if you have difficulty going to sleep or staying asleep because of disturbances to your normal routine.
One tablet should be taken at bedtime or up to an hour after going to bed if you are having difficulty falling asleep.
What is it used for?
Sleep aid for temporary relief of sleeping difficulties (insomnia) in adults.
Adults and children aged over 12 years: Take two tablets at bedtime if needed, or as directed by your doctor.
Do not use this medicine for longer than seven days without seeking medical advice from your doctor.
This medicine may cause drowsiness that can last up to 12 hours. If affected you should not perform potentially hazardous tasks such as driving or operating machinery. You should avoid drinking alcohol when taking this medicine.
This medicine may interfere with some pregnancy tests, causing false negative or false positive results.
If you are due to have any skin prick tests to diagnose allergies you should stop taking this medicine at least 72 hours before the tests. This is because antihistamines can prevent or lessen the skin reactions that indicate an allergy, and so can make the test results unreliable.
