Pharmacist-only medicine (POM)

Definition

In Australia, therapeutic goods are classified into categories based on how they can be supplied. A pharmacist-only medicine (POM) is a therapeutic good that is listed in Schedule 3 or 4 of the Australian Poisons Standard. These medicines can only be supplied by a registered pharmacist from a pharmacy, but do not require a doctor's prescription. The pharmacist supplies the medicine directly to the patient after assessing that the medicine is appropriate for the patient's stated condition or symptom. Pharmacist-only medicines represent an intermediate level of regulation between unscheduled products (available without any restrictions) and prescription medicines (only available with a doctor's prescription). Many peptide therapeutics that might be considered 'self-limiting' (e.g., injectable peptides for minor conditions) might theoretically fall into this category, though most approved peptide therapeutics are prescription-only due to complexity of use and monitoring requirements. The pharmacist's professional judgment is relied upon to ensure appropriate use of pharmacist-only medicines.

The Poisons Standard (National Standard for Medicines and Poisons) is administered by the APVMA (Australian Pesticides and Veterinary Medicines Authority) and the TGA (Therapeutic Goods Administration). Schedule 3 and 4 medicines are listed in this standard, with specific requirements for labelling, storage, and supply. A Schedule 3 medicine requires 'restricted sale' — the pharmacist must verify that the patient has a suitable condition before supplying. A Schedule 4 medicine requires 'prescription only' in most cases, though some Schedule 4 substances can be supplied on pharmacist initiative in limited circumstances.

For peptide therapeutics, the pharmacist-only pathway is less commonly used than prescription-only because most peptides require medical oversight for appropriate dose, monitoring, and management of adverse effects. However, understanding the pharmacist-only classification is relevant for educational purposes and for understanding the Australian regulatory framework.
