Sominex Sleeping Tablets

Sominex Sleeping tablets are a medicine used to aid sleep at night time. They contain an ingredient called promethazine hydrochloride, an antihistamine with a sedative effect that can correct difficulty in going to sleep and staying asleep.

Although promethazine hydrochloride is primarily used to relieve allergies, it can be used for short-term sleep problems such as insomnia. Before taking Sominex Sleeping Tablets, you should first try and use natural remedies to your sleeping problems. These can include:

  • Trying to go to bed at a consistent time
  • Getting plenty of sunlight
  • Regular exercise

More information about Sominex Sleep Tablets main ingredient can be found on the NHS website.

Sominex 16 Tablets

Each pack contains Sominex 16 Tablets with no other pack size available. At My Pharmacy UK we currently offer a maximum of one box of Sominex 16 tablets pack.

Sominex Herbal

Sominex Herbal is an herbal alternative to Sominex sleeping tablets. Instead of containing the antihistamine promethazine hydrochloride, Sominex herbal contains extracts of flowers and herbs. It contains extracts of Hop Strobile, Valeria and Passion Flower.

Sominex Herbal may not be suitable as an alternative to Sominex Sleeping tablets if you are allergic to the ingredients, under the age of 18 and are already taking medicine for sleep or anxiety.

Sominex Drug

Sominex drug interactions may be a problem for someone who is already taking other medication for sleeping or anxiety disorders. There are currently eleven major sominex drug interactions, 387 moderate Sominex drug interactions and 2 minor Sominex drug interactions.

One of these major Sominex drug interactions is depression. A variety of abnormal thinking and behaviour changes have been reported when sedatives are used, particularly in people who have had a history of depression. The sominex drug should be administered carefully with these patients and monitored closely. Large quantities of Sominex tablets should be avoided in patients who have a history or are currently showing signs of depression.
