The Belgian consumer organization Testaankoop is calling for urgent government intervention to curb the proliferation of unregulated advertisements for prescription weight-loss medications. The demand follows a significant legal crackdown in France, where regulators imposed multi-million euro fines on entities promoting prescription drugs to the general public, highlighting a growing gap in consumer protection across European borders.
At the center of the controversy are GLP-1 receptor agonists, a class of medications originally developed for type 2 diabetes that have surged in popularity as weight-loss tools. While these drugs are strictly prescription-only, Testaankoop warns that a “wild west” atmosphere has emerged on social media platforms, where influencers and unregulated clinics market these substances as lifestyle shortcuts rather than medical treatments.
The organization argues that the Belgian government must transition from passive monitoring to active enforcement to prevent public health risks and ensure that these potent medications are administered only under strict medical supervision. The push for tighter weight-loss medication advertising in Belgium comes as health authorities struggle to keep pace with the viral nature of “miracle cure” narratives on TikTok and Instagram.
The French Precedent: A Warning for Brussels
The catalyst for Testaankoop’s current campaign is the aggressive stance taken by France’s Direction générale de la concurrence, de la consommation et de la répression des fraudes (DGCCRF). French regulators have recently issued substantial fines totaling millions of euros against providers and platforms that bypassed laws prohibiting the advertising of prescription-only medicines (POMs) to the public.

Under European Union law, specifically Directive 2001/83/EC, the advertising of medicinal products to the general public is prohibited if the product is available only on prescription. The French authorities determined that promoting these drugs as simple weight-loss solutions constituted a deceptive commercial practice and a violation of public health safety protocols.
Testaankoop contends that similar violations are occurring within the Belgian digital landscape, but without the corresponding financial penalties that would deter companies from exploiting vulnerable consumers. The organization suggests that the lack of high-profile sanctions in Belgium creates a perceived “safe haven” for those skirting pharmaceutical laws.
The Risks of ‘Lifestyle’ Prescribing
Medical professionals have expressed growing concern over the “off-label” use of GLP-1 drugs for cosmetic weight loss. These medications, which include well-known brands like Ozempic and Wegovy, can cause significant side effects, including severe gastrointestinal issues and, in rare cases, pancreatitis.

When these drugs are promoted via social media, critical medical screenings—such as assessing a patient’s history of medullary thyroid carcinoma or kidney function—are often bypassed. Testaankoop emphasizes that the glamorization of these drugs leads consumers to view them as supplements rather than powerful hormones that alter metabolic processes.
Beyond individual health risks, the surge in demand driven by unregulated advertising has contributed to global supply shortages. This has left patients with type 2 diabetes, for whom the medication is life-critical, struggling to secure their necessary prescriptions.
Comparison of Regulatory Approaches
| Region | Primary Enforcement Action | Regulatory Stance |
|---|---|---|
| France | Multi-million euro fines via DGCCRF | Aggressive prosecution of deceptive marketing |
| Belgium | Monitoring and administrative warnings | Reactive; calls for increased enforcement |
| European Union | Directive 2001/83/EC | General prohibition of POM advertising to public |
Closing the Enforcement Gap
Testaankoop is specifically urging the Federal Agency for Medicines and Health Products (FAMHP) to increase its surveillance of digital platforms. The organization argues that traditional monitoring of print and television media is no longer sufficient in an era where targeted algorithms deliver medical misinformation directly to high-risk demographics.

The consumer group is calling for a three-pronged approach to address the issue:
- Heavier Financial Penalties: Implementing fines that mirror the French model to ensure that the cost of non-compliance outweighs the profit from illegal advertising.
- Platform Accountability: Working with social media giants to proactively remove ads for prescription-only weight-loss drugs.
- Public Awareness Campaigns: Launching government-led initiatives to educate the public on the dangers of obtaining prescription medication through non-traditional channels.
Critics of the current system note that many “clinics” operate in a grey area, offering “consultations” that are essentially sales pitches for these medications, further blurring the line between healthcare and commercial retail.

The Belgian government has yet to announce a formal policy shift in response to Testaankoop’s demands. The next critical checkpoint will be the upcoming review of pharmaceutical advertising enforcement by the FAMHP, where the agency is expected to address the rise of digital health misinformation.
