‘Hi there, I am writing to make a request under the freedom of information act. Please could you tell me the number of unique patients in England under the age of 18 who have been prescribed antidepressants (BNF Section 0403) between January 2019 and including July 2022 or the most recent date available, broken down both by month AND by the age of the patients according to the following age categories: 0-6, 7-11, 12-17? Please include information for prescriptions issued in England but dispensed elsewhere. Many thanks,’


July 2022

Please note that this information is not yet available. That data became available on 20 July so we were not able to include this information in this response. Please submit a fresh request if you still require the data for July 2022.

Remaining Data

A copy of the information is attached. Please read the below notes to ensure correct understanding of the data.

These medicines are classified by their primary therapeutic indication. However, it is possible that they can be prescribed for other reasons outside of this primary therapeutic indication. For example, some antidepressants can be used to treat people suffering from chronic primary pain. The clinical indication of a prescription is not captured by the NHSBSA during processing, and therefore we cannot determine the reason that a prescription was issued. Due to this, these statistics may not give an accurate estimation of the population receiving treatment for a specific mental health condition.

Drug therapy is just one way that mental health conditions can be treated. These statistics do not give an indication of the number of patients accessing other mental health services, such as psychological therapy.

Data Quality

NHS Prescription Services have a variety of validation streams throughout prescription processing to support accurate capture of the data. In addition, a retrospective sample is completed in the month following reimbursement to identify the accuracy of prescription processing information. The check includes the accuracy of prescriber, practice and drug information, but does not include the personal details of the patient. The information is used to populate a number of Key Performance Indicators, the results of which are published on a monthly basis on the NHSBSA website at:

NHSBSA stores information on the age of the recipient of each prescription as it was read by computer from images of paper prescriptions or as attached to messages sent through the electronic prescription system.

The NHSBSA does not validate, verify or manually check the resulting information as part of the routine prescription processing. However an additional check is carried out on a yearly basis to check the capture rate and accuracy of the stored patient information. The results of this check for the most recent time period available (January 2020 to December 2020) show that for both paper and electronic prescriptions patient age was captured from 94.88% of prescription forms and the accuracy of age data captured was 99.95%.

When considering the accuracy of age data it is expected that a small number of prescriptions may be allocated against any given patient age incorrectly.


NHSBSA Prescription Services process prescriptions for Pharmacy Contractors, Appliance Contractors, Dispensing Doctors and Personal Administration with information then used to make payments to pharmacists and appliance contractors in England for prescriptions dispensed in primary care settings (other arrangements are in place for making payments to Dispensing Doctors and Personal Administration). This involves processing over 1 billion prescription items and payments totalling over £9 billion each year. The information gathered from this process is then used to provide information on costs and trends in prescribing in England and Wales to over 25,000 registered NHS and Department of Health and Social Care users.

Data Source

Data in ePACT2 is sourced from the NHSBSA Information Services Data Warehouse and is derived from products prescribed on prescriptions and dispensed in the Community. The data captured from prescription processing is used to calculate reimbursement and remuneration. It includes items prescribed in England, Wales, Scotland, Northern Ireland, Guernsey / Alderney, Jersey and Isle of Man which have been dispensed in the community in England. English prescribing that has been dispensed in Wales, Scotland, Guernsey / Alderney, Jersey and Isle of Man is also included.

The Data excludes:

• Items not dispensed, disallowed and those returned to the contractor for further clarification.

• Prescriptions prescribed and dispensed in Prisons, Hospitals and Private prescriptions.

• Items prescribed but not presented for dispensing or not submitted to NHS Prescription Services by the dispenser.

Time Period

Year Months January 2019 - June 2022

Organisation Data

The data provided is for prescriptions prescribed in England regardless of where they were dispensed.


This dataset is limited to BNF Section 0403 - Antidepressant drugs with the following age banding applied: Aged 0-6 Aged 7-11 Aged 12-17

Patient Identification

Where patient identifiable figures have been reported they are based on the information captured during the prescription processing activities. Please note, patient details cannot be captured from every prescription form and based on the criteria used for this analysis, patient information (0-17 age and NHS number) was captured for 99.21% of prescription items for 0-17 year olds were captured as patient identifiable.

The patient count figures are based on a distinct count of NHS number as captured from the prescription image.

Patient ages are based on the age as captured from the prescription image and relates to the patient's age at the time of prescribing/dispensing. Results have been restricted to only show results for patients aged 17 and under with results presented by age band (0-6, 7-11, 12-17). Please note it is possible that a single patient may be included in the results for more than one age band where a patient has received prescribing at different ages during the time period (Jan 2019 - June 2022).

The figures for the number of identifiable patients should not be combined and reported at any other level than provided as this may result in the double-counting of patients. For example, a single patient could appear in the results for multiple age bands and/or time periods.
