You may be prescribed medicines (tablets or injections) as part of the care plan to help with your recovery.


In some cases there are a number of different drugs available to treat the same illness. The prescriber working with you will choose which treatment is most appropriate based on your specific needs and health, involving you as fully as possible in that choice.

All medicines have potential side effects which can vary from one person to another. In most cases there are no or just mild effects, but for a few people the side effects they experience may be more serious. As part of the discussions about your care, the person prescribing your course of medication will explain the possible side effects associated with the drugs being recommended for you.

The Trust has subscribed to the website Choice and Medication which offers current information about medication used in the mental health settings explaining the key features, including side effects, for the most common medicines. These are available in an easy to read and understand format, which provides useful information on the medication you may have been prescribed.

The Trust Medicines Formulary and Trust CAMHS Formulary are dynamic documents, which include information on mental health drugs stocked within our four hospitals.

The documents are reviewed and updated in line with new drugs or indications that are approved by the Drugs and Therapeutics Committee.

Medicines which have been approved for the use by the National Institute for Health and Care Excellence (NHS) are automatically included in the Medicines Formulary and CAMHS Formulary once it has been discussed by the Drugs and Therapeutics Committee.

Treatment guidelines are included for some aspects of drug therapy, however these should be tailored where necessary to individual patient needs. These guidelines do not replace the need for consultation with senior staff and/or referral for expert advice.

All dosages in the Formulary are for general guidance and represent the BNF recommended doses that are generally regarded as being suitable for adults.

All dosages in the CAMHS Formulary are for general guidance and represent the CBNF recommended doses that are generally regarded as being suitable for children and adolescents.

The aims of the formulary are as follows: 

  • to aid clinicians in cost-effective and evidence based prescribing
  • to reflect the views and practice of expert clinicians for the benefit of junior medical staff
  • to educate junior staff in good practice in the selection and use of drugs
  • to provide the user with prescribing information and guidelines
  • to provide the user with a list of mental health drugs available from the pharmacies at Barnet General Hospital, Chase Farm Hospital, Edgware Community Hospital and St Ann's Hospital.

Information for young people

HeadMeds is a unique new website about mental health medication for young people aged 13-25. It has been created by YoungMinds and funded by Comic Relief and the Nominet Trust as part of the Innovation Labs project which has developed a range of digital projects to improve young people's mental health.

This website has information about:

  • potential side effects
  • when a young person should go and get help
  • answers to some of the difficult questions that young people may have around their medication, but may feel uncomfortable asking their GP about
  • real life stories.

This website is created side by side with young people. HeadMeds provides much needed, straight talk on mental health medication whenever young people need it.
