Warnings about almost 3300 patients were sent to doctors and pharmacists during the first two-month trial of Victoria’s real-time script-tracking software, the state government says.

The software, called SafeScript, was rolled out in more than 400 GP clinics and pharmacies in October to combat prescription drug misuse.

When users prescribe or dispense a monitored medicine, including all schedule 8 drugs and some schedule 4 drugs, the system alerts them if the patient has previously been prescribed a monitored drug from a different doctor.

They can then check a full list of monitored medicines prescribed to the patient.
