Provides detailed information on all antipsychotic drugs currently available in the UK.


Promazine is a first generation antipsychotic.

You can find detailed information about this drug in the official Patient Information Leaflet (PIL). This includes information on what the medication is for, how to take it, possible side effects and safety information.

This leaflet should come with your medication, usually inside the box. Or you can download a PDF version of the PIL for your medication:

Some drugs come in different forms, such as tablets or liquid. There may be a separate PIL for each form of the drug, as well as for different doses. You should look at the PIL for the form and dose you have been prescribed.

You can also search these websites for your specific drug to find further information and PILs:

If you have any questions about your medication you can:

  • talk to your doctor, or any healthcare professional who prescribes your medication
  • speak to someone at a pharmacy
  • contact NHS 111 if you live in England
  • contact NHS 111 or NHS Direct (0845 46 47) if you live in Wales.

If you experience any side effects from your drug, you can report them to the MHRA via their Yellow Card scheme. This scheme allows the MHRA to collect information about which drugs cause which side effects and how common they are. This lets drug manufacturers give more accurate information about their medication.
