Pharmacists who dispense repeat prescriptions for Warfarin must review the patient-held record, which includes the date of the last clinic appointment, the latest INR test result and current dose, and confirm this information with the patient, as recommended by the NPSA.

The NPSA also recommends that prescribing and dispensing software should include functionality to enable the date of the last clinic appointment, the latest INR test result and current dose to be recorded when this information is being checked prior to issuing or dispensing a repeat prescription for an oral anticoagulant.

If you have any queries please contact the Anticoagulant Service.
