Promethazine: Effect On The Body

Promethazine belongs to a group of drugs called antihistamines. Promethazine is a ‘first generation’ antihistamine. This group of antihistamines is characterized by having sedative properties.

The primary mechanism of action of Promethazine is to ‘block’ histamine receptors in the body, hence acting as an antihistamine.

Promethazine Cough Syrup: What Are The Options?

There are no products in the UK marketed as promethazine cough syrup. Promethazine, however, is included in some liquid medicines, which are used to relieve symptoms of colds and influenza at night, alongside other active ingredients, which together help with the management of coughs.

Five liquid products available in the UK which contain promethazine include:

  • LloydsPharmacy Night Cold and Flu Relief Oral Solution
  • Numark Night Cold and Flu Oral Solution

Nigh Nurse Liquid As Promethazine Cough Syrup

Nigh Nurse Liquid As Promethazine Cough Syrup

Nigh Nurse liquid is probably the most known and most popular ‘cold and flu’ product available in UK pharmacies.

The active ingredients contained in Night Nurse product include:

  • dextromethorphan hydrobromide
  • paracetamol
  • promethazine hydrochloride

Night Nurse is licensed for symptomatic management of cold and flu symptoms at night. Adults and children over 16 years of age can use nigh Nurse liquid. Dextromethorphan is a medication commonly added to over-the-counter cough and cold products. Dextromethorphan is related to morphine; however, it does not have analgesic (pain reducing) or addictive properties.

Overall, there are conflicting results in terms of the effectiveness of dextromethorphan in reducing coughs with many studies and reviews describing the lack of efficacy of this drug (Paul et al, 2007). Paracetamol is added in the formulation of Night Nurse to help with fever (reduce body temperature), pain and headaches.

Promethazine plays the role of a sedative agent to help with sleep.

Each 20ml of Nigh Nurse contains 20mg of Promethazine.

Promethazine Cough Syrup: Conclusion

Promethazine cough syrup is not available in the UK. A combination of cold and flu products containing Promethazine and cough suppressant exist, with Night Nurse being the most popular. Promethazine can be purchased as a drug on its own, in the form of liquid solutions and tablets.

Promethazine is used mainly for the management of allergies and as a sleeping aid. Promethazine does not suppress the cough on its own. Patients who wish to manage coughs have a choice of different products available from UK pharmacies and supermarkets.

Primary products used in the management of coughs include the following drugs:

  • dextromethorphan for treatment of dry coughs, available in liquid formulations, for example, Benylin Dry cough, Covonia Original Bronchial Balsam Syrup
  • pholcodine for the treatment of dry coughs, available in liquid forms or capsules (Day Nurse)
  • guaifenesin for the treatment if chesty coughs
  • diphenhydramine hydrochloride (another sedative antihistamine) in combination with levomenthol (for example Benylin Dry Coughs Night Syrup) or dextromethorphan (for example Covonia Night Time Formula)
