ADHD medicines supply change

From 1 June, methylphenidate and dexamfetamine are funded for up to three months’ supply when prescribed through the New Zealand ePrescription Service (NZePS). Dispensing frequency remains monthly, and the maximum amount of medicine at each dispensing does not change.1

Supply via NZePS may improve equity of access to ADHD medicines, as patients now only need to obtain a new prescription every three months (supply by paper prescription remains limited to one month). Prescribers can issue prescriptions with shorter supply periods, or increase dispensing frequency, as appropriate.1

This Pharmaceutical Schedule rule change aligns funding with December 2022 legislative changes expanding the NZePS.2
