Authorities for health practitioners working with medicines

Under the Medicines and Poisons Regulations, health practitioners are legally authorised to do certain things with medicines, such as purchase, prescribe or administer.

What a practitioner can do is dependent on their individual profession and any additional training or endorsement they hold.

Types of medicines authorities

Possible types of medicines authorities include:

  1. obtain (also called purchase) – legally buying medicines from a pharmaceutical wholesaler
  2. possess – store a medicine for later use
  3. prescribe – write a prescription to instruct a pharmacist to dispense a medicine
  4. administer – administer a dose of a medicine to a patient when instructed by prescriber
  5. supply – when a prescriber gives a quantity of medicine to a patient to take
  6. dispense – when a pharmacist supplies on the instruction of a prescription.
Pharmacists can also manufacture a medicine, which may include taking several substances and turning this into therapeutic product.

Important restrictions
All medicines authorities are subject to important restrictions. In general, any use of a medicine is limited to genuine therapeutic need, lawful practice or business, and professional scope.

In cases of misconduct or unlawful behaviour a condition may be applied to the authority of an individual, or in extreme cases revoked.

For more details on relevant restrictions that may apply practitioners should review guidance for each profession.
