Approved vs Unapproved Therapeutic Goods: What Is the Difference?

Introduction

Consumers may encounter therapeutic goods online that are described as approved, registered, listed, compounded, investigational or unapproved (Therapeutic Goods Administration, 2026a).

These terms describe different regulatory circumstances and should not be treated as interchangeable (Therapeutic Goods Administration, 2026a).

Understanding the distinction can help consumers interpret health information more accurately.

What is an approved or registered medicine?

Medicines included in the ARTG have entered the Australian regulatory system through the applicable regulatory pathway (Therapeutic Goods Administration, 2026a).

The regulatory requirements applied to a medicine depend on its classification and pathway (Therapeutic Goods Administration, 2026a).

For medicines that require evaluation for registration, the TGA considers relevant information concerning quality, safety and efficacy as part of the regulatory process (Therapeutic Goods Administration, 2026a).

What is an unapproved therapeutic good?

An unapproved therapeutic good is a therapeutic good that has not been included in the ARTG in the relevant manner (Therapeutic Goods Administration, 2026a).

There are circumstances in which certain unapproved therapeutic goods may be accessed under specific exemptions or pathways, but those circumstances do not mean that the product has been evaluated by the TGA in the same way as an ARTG-included medicine (Therapeutic Goods Administration, 2026a).

The regulatory pathway therefore matters when interpreting claims about a product.

Does “unapproved” mean “unsafe”?

Not necessarily.

“Unapproved” describes regulatory status and does not by itself establish the safety profile of a particular product (Therapeutic Goods Administration, 2026a).

However, an unapproved therapeutic good has not undergone the same TGA product evaluation process applicable to an approved or registered product (Therapeutic Goods Administration, 2026a).

Consumers should therefore avoid treating an unapproved product as though it has the same regulatory status as an ARTG-included medicine.

Does scientific research make a product approved?

No.

A substance can be the subject of peer-reviewed research without being approved or included in the ARTG for therapeutic use in Australia (Therapeutic Goods Administration, 2026a).

Similarly, publication of a laboratory or clinical study does not itself create regulatory approval.

Scientific evidence and regulatory status are related but separate questions.

Why do clinical trials matter?

Clinical trials are used to evaluate interventions in human participants under defined research protocols (World Health Organization, 2024).

Different phases of clinical research address different questions, including safety, dosing, pharmacological effects and efficacy (World Health Organization, 2024).

A promising early-stage finding therefore does not necessarily establish that a product has demonstrated the safety and efficacy required for routine clinical use.

What about advertising?

Advertising restrictions can apply independently of whether a substance has been the subject of scientific research (Therapeutic Goods Administration, 2026b).

The TGA states that prescription medicines generally cannot be advertised to the public except in limited circumstances (Therapeutic Goods Administration, 2026b).

For health-service advertising involving prescription medicines, the TGA states that direct and indirect references to prescription medicines are generally prohibited (Therapeutic Goods Administration, 2026c).

Ahpra’s advertising framework also requires advertising of regulated health services to avoid misleading claims, unreasonable expectations of beneficial treatment and encouragement of unnecessary use (Ahpra and National Boards, 2020).

Key takeaway

“Scientifically researched”, “ARTG included”, “prescription-only”, “compounded” and “unapproved” are not interchangeable terms.

Each describes a different aspect of a therapeutic good’s scientific or regulatory context.

Understanding these distinctions is one of the most useful ways consumers can critically assess health information online.
