ADHD prescribing rules in Northern Territory

Chief Health Officer authorisation is required for each individual patient, and only a defined specialist list can make the decision to start treatment.

The Northern Territory has not opened a GP diagnosis or standing authority pathway. Its rules read the way most of the country read before September 2025, with one detail worth knowing: co-management is explicitly permitted, on a defined review interval.

Who grants approval: NT Health, Medicines and Poisons Control
Governing law: Medicines, Poisons and Therapeutic Goods Act 2012
Prescription monitoring: NTScript

The rules at a glance

ADHD stimulant prescribing in Northern Territory, as published by NT Health, Medicines and Poisons Control
Rule	Position	Detail
Specialists who can start	Yes Paediatricians, psychiatrists, physicians, neurologists	Only paediatricians, psychiatrists, physicians, neurologists and registrars training in these disciplines may make the decision to initiate supply. Specialists may initiate without an authorisation but must obtain one if supply exceeds 30 days.
Can a GP start it	No No	The decision to initiate supply is limited to the specialist list, so a GP cannot start treatment.
Can a GP continue it	With approval After a specialist has started	Other medical practitioners may continue supply once one of the listed specialists or registrars has initiated it, under a per patient CHO authorisation.
Government approval	With approval CHO authorisation per patient	Authorisation from the Chief Health Officer is required for each individual patient before a prescription can be issued for dexamfetamine, lisdexamfetamine or methylphenidate.
Nurse practitioners	With approval Same authorisation rule	Nurse practitioners are named among the authorised prescribers subject to the Act, and the per patient authorisation requirement is written around the substance rather than the prescriber's profession.
Age rules	Yes No published age threshold	The NT page on Schedule 8 medicines does not publish an age threshold for psychostimulants. It sets a review interval instead: under co-management the patient must be seen by a specialist or registrar at least every two years.

Restricted Schedule 8 substances

The Northern Territory splits Schedule 8 substances into restricted and unrestricted. Dexamfetamine, lisdexamfetamine and methylphenidate are all restricted, which places them alongside the opioid dependence treatments rather than alongside common analgesics such as morphine and oxycodone.

For restricted substances, authorisation from the Chief Health Officer is required for each individual patient before a prescription can be issued. Prescribers must also check the monitored medicines database, NTScript, before issuing a prescription for a monitored medicine.

Who may start, and who may continue

Only paediatricians, psychiatrists, physicians, neurologists and registrars in training in those disciplines may make the decision to initiate supply. Other medical practitioners may continue supply after one of those prescribers has started it, and under that co-management arrangement the patient must be seen by a specialist or registrar at least every two years.

There is one timing detail that catches people moving to the Territory: a specialist may initiate supply without an authorisation, but must obtain one if supply exceeds 30 days. In practice that makes the authorisation a near certainty for any ongoing ADHD treatment.

Prescriptions from interstate

The Northern Territory permits electronic prescriptions for Schedule 4 and Schedule 8 medicines, including interstate prescriptions, though separate regulations apply to prescriptions written interstate. NT Health publishes direct phone and fax contacts for every other state and territory drug monitoring unit, which is the practical route when a prescription has to be transferred.

Common questions about prescribing in NT

Can a GP prescribe ADHD medication in the Northern Territory?

A GP can continue treatment once a paediatrician, psychiatrist, physician, neurologist or a registrar training in those disciplines has started it, under an authorisation covering that patient. A GP cannot make the decision to start treatment.

How often do I need to see a specialist in the NT?

Under a co-management arrangement, at least every two years. That interval is set in the NT rules rather than left to the prescriber.

Is an authorisation always needed?

For an ongoing prescription, effectively yes. A specialist may initiate supply without an authorisation but must obtain one once supply exceeds 30 days, and any other prescriber needs one from the outset.
