Buy Sominex One A Night 20mg - 16 Tablets

Sominex tablets contain promethazine hydrochloride, an antihistamine with a calming, sedative effect. This medicine is designed to help you get a good night’s sleep, especially if your usual sleep pattern has been disrupted. 

Sominex can make it easier to fall asleep and stay asleep when changes to your routine, such as travel or shift work, make it challenging to rest properly.

Directions

Always take Sominex exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. For adults and children over 16 years, the recommended dose is one tablet taken at bedtime. 

If you find it difficult to fall asleep, take the tablet up to one hour after going to bed. However, this medicine should not be used for more than seven consecutive days. 

For further information on the directions of Sominex, please refer to the patient information leaflet.

Warnings

  • Do not take these tablets if you are allergic to promethazine or any of the other listed ingredients.
  • Tell your prescriber if you are taking or have taken any other medicines.
  • These tablets are unsuitable for anyone under the age of 16.
  • Sominex should not be taken 2 weeks before birth; do not take if you are breastfeeding. This medicine may impact the results of a pregnancy test.
  • These tablets will cause drowsiness; do not drive or operate machinery.
  • Do not drink alcohol while taking these tablets.
  • These tablets contain lactose and 23mg of sodium per tablet.
