Questions about Patient Specific Directions (PSD)

A Patient Specific Direction (PSD) is the traditional written instruction, signed by a doctor, dentist, or non-medical prescriber for medicines to be supplied and/or administered to a named patient after the prescriber has assessed the patient on an individual basis.

Where a Patient Specific Direction exists, there is no need for a Patient Group Direction (PGD).

In practice a PSD is commonly referred to as a prescription by those who write and follow them because this indicates that it is written by a prescriber.

The PSD Q&A document attached below was developed in 2013 and updated in July 2018. It has been approved by the  members of the PGD Website Board, including the MHRA, NHS Specialist Pharmacy Service, Department of Health and the CQC.

It is intended to be read as a complete document to help provide the full context in practice.
