3. Prescriber - Prescription MedicationRequest Cancellation
An electronic prescription MedicationRequest can be cancelled after submission to EPS provided the prescription has not been downloaded or processed by a dispenser.
To cancel a prescription the prescribing system is required to send a prescription-order-update cancellation message to the FHIR Operation process-message. A cancellation is at individual item level. Cancellation is applicable to all types of electronic prescriptions (i.e. acute, continuous prescribing and continuous dispensing prescriptions).
Example cancellation message Prescription Order Outpatient Cancel which cancels the Morphine medication.
| Medication ID (SNOMED) | Medication Name | Prescribed Quantity | Unit of Measure |
|---|---|---|---|
| 36126511000001106 | Morphine 10mg modified-release tablets | 28 | Tablet |
Note: this prescription is being cancelled by a clerical worker and the original prescriber is now down as the responsible party.
4. Prescriber - Prescription Cancellation Response
The immediate response to a cancellation messge is a prescription-order-response FHIR Message. Example message Prescription Order Outpatient Response
5 Prescriber - Contact Pharmacy
Prescriptions sent to a nominated pharmacy are likely to be collected before they have been cancelled. This has happened in the above example and the prescriber SHOULD contact the pharmacy to cancel the prescription.
6 Dispenser - Dispense Proposal Withdrawal
As no Medications have been dispensed, the pharmacy can return the entire prescription back to EPS. This is performed sending a FHIR Task to EPS Task endpoint. Note the full prescription must be returned to allow a single MedicationRequest to be cancelled.
PUT /Task
Example payload Task Return Prescription Order
7 Prescriber - Subsequent Cancellation Response
As the prescription has now been returned to EPS, EPS can now send a prescription-order-response message to the prescriber. This is sent via MESH and example payload:

8 Dispenser - Re-Release Prescription
The dispenser can now download the modified prescription for dispensing. This is similar to step 2.
