The rise of GLP-1 medications has reshaped weight-loss conversations in Australia, delivering results that once felt impossible for many people. But the TGA’s latest update has added a necessary pause to the excitement. For the first time, mental-health risks are now listed across all GLP-1 drugs, and Mounjaro carries a separate contraception warning. These changes are not meant to discourage use. Instead, they highlight emotional and hormonal factors often overlooked in fast-moving weight-loss trends and encourage stronger communication between GPs and patients (Australia weight-loss warning).

Demand for GLP-1 medications has exploded across the country, with national prescription numbers passing two million this year. Weight loss is no longer a slow journey for many Australians. Ozempic and Mounjaro have offered faster, more reliable results, especially for those juggling long work hours or chronic health concerns. Yet the TGA’s update shows that rapid adoption must be paired with early awareness of emerging risks.
New Mental-Health Warnings Reflect Emotional Complexity (Australia weight-loss warning)
Reports of depression, anxiety, and sudden emotional drops prompted the TGA to strengthen safety labels across every GLP-1 brand. These cases remain rare, but their seriousness demands attention. International studies throughout 2024 recorded similar trends, pushing regulators to act before more incidents appear. The new warnings encourage Australians to track their emotional wellbeing closely and contact their doctor at the first sign of unusual mood changes.

Mounjaro has a distinct pharmacological effect: it delays stomach emptying more than other GLP-1 drugs. This delay can disrupt how oral contraceptives are absorbed. Because hormonal pills require predictable timing, slower digestion may lower their effectiveness. Women must now use backup contraception for four weeks after starting Mounjaro or after increasing their dose. The goal is simple—reduce the chance of unintended pregnancy, as GLP-1 drugs cannot be used safely during pregnancy.
GPs Must Now Take a More Holistic Approach
In response, guidance from the Royal Australian College of General Practitioners (RACGP) now encourages doctors to take a broader, more holistic approach before prescribing GLP-1 treatments. Specifically, GPs are advised to consider emotional health, hormonal factors, and individual lifestyle patterns rather than focusing solely on weight outcomes. As part of this process, doctors must ask about past mental-health challenges, family planning intentions, and even sleep habits, all of which can influence how patients respond to treatment.
Equally important, the guidance stresses the need for close monitoring early in therapy. In particular, follow-up appointments during the first two to three months are essential, as this period carries the highest risk of unexpected emotional or physical reactions. Over time, this structured approach gives GPs a clearer and more complete picture of how each patient adapts to treatment, allowing them to adjust care plans early and support safer, more personalised outcomes.
Why the TGA Released This Warning at This Moment
More broadly, Australia is aligning with growing global concern about the risks associated with GLP-1 medications. At the same time, regulators in Europe and the United States are conducting similar safety reviews, while the World Health Organization has flagged emerging patterns in psychiatric adverse-event reports. In this context, Australia’s decision reflects not only international findings but also the rise in locally reported incidents.
Accordingly, the Therapeutic Goods Administration has emphasised that early and clear communication is essential. By doing so, the regulator aims to prevent public confusion, and in turn, help Australians make safer, more informed, and more confident decisions about their treatment options.
Overall, Australia’s new weight-loss warning marks a more mature phase in the country’s relationship with GLP-1 medications. While these drugs remain valuable tools, they also involve emotional and hormonal factors that deserve closer attention. As a result, the strengthened warnings encourage Australians to recognise their own mental-health patterns, at the same time reconsider contraception planning, and importantly maintain a steady partnership with their GP. In the long run, this shift supports safer, more informed, and ultimately more sustainable use of these powerful treatments.
