Medication is a form of treatment for many health conditions. Some medicines are available from pharmacists or supermarkets, others need a prescription from your GP or another healthcare professional.

CNWL's pharmacy service specialises in mental health medicines and can help you make the best use of your medicines by providing information, education and expertise.
