Is Lamivudine legal in Australia?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Yes. Lamivudine is an approved medicine in Australia, classified as "TGA-registered, prescription only". Approval covers its labeled indication and it is supplied on prescription, not over the counter. Products labeled "research use only" fall outside that approval and the label does not make human use lawful. On the evidence, 2 human studies are cited on its profile.

What this means
- 01
TGA has approved Lamivudine for at least one labeled indication, so a pharmaceutical-grade product exists in Australia and is dispensed on prescription.
- 02
Approval is indication-specific. Uses outside the label are a clinical decision for a prescriber, not something the approval itself authorizes.
- 03
Unlicensed online vials, including those labeled "research use only", are not the approved product and are not covered by the approval.
What Lamivudine is
A thirty year old HIV and hepatitis B drug repurposed on the hypothesis that LINE-1 retrotransposons drive the sterile inflammation of ageing. The human ageing evidence is one 12 person open-label pilot in Alzheimer disease with no control group.
Roughly 40 percent of the human genome is retrotransposon sequence. Most of it is silenced, and the silencing appears to fail with age.
Mechanism: A cytidine analogue that is phosphorylated intracellularly to lamivudine triphosphate, which is incorporated by reverse transcriptase and terminates the growing DNA chain because it lacks a 3 prime hydroxyl group. In HIV and hepatitis B that stops viral replication.
Regulatory history: FDA approved for HIV-1 infection in combination therapy and, as a separate lower-dose product, for chronic hepatitis B. Not approved for ageing, inflammation or neurodegeneration.
How TGA treats this kind of product
Registers or lists therapeutic goods on the ARTG and schedules substances in the Poisons Standard. Many peptides are Schedule 4 (prescription only), so possession without a prescription and personal importation are restricted even when no product is registered.
The classification above is the The Longevity Archive reading of Therapeutic Goods Administration listings for Lamivudine at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
