Dutch poison centre warns of surge in slimming drug poisonings

The number of reported poisonings linked to slimming medications has nearly doubled in the Netherlands over the past year, with health authorities warning of a surge in self-experimentation using unapproved injectable treatments purchased via social media. The National Poisons Information Centre (NVIC) recorded 149 cases in 2025, up from 76 in 2024, according to figures released on Monday .
The NVIC’s annual report highlights a sharp rise in poisonings from both registered and experimental slimming drugs, including peptides that have not received official regulatory approval. Experts cite the normalisation of injectable treatments—often marketed on platforms such as TikTok and Instagram—as a key driver of the trend. “Young people are actively engaging with these products, and the risks are being downplayed,” an NVIC spokesperson told *NRC* .
The centre has also flagged concerns over the use of unregulated substances, with first-time reports in 2025 of poisonings linked to peptides that lack formal authorisation as medicines. While registered slimming medications remain a significant source of cases, the proliferation of experimental products—often sold under the guise of “wellness” or “biohacking”—has compounded the problem. “People are injecting substances they don’t understand, with no oversight,” said a toxicologist quoted in *Trouw* .
Health officials are urging caution, noting that the long-term effects of these substances remain unknown. The NVIC’s data underscores a broader shift in consumer behaviour, where social media influencers and online vendors promote unproven treatments with little regard for safety. “This is not just a health issue—it’s a public health crisis in the making,” warned RTL News .
The surge in poisonings coincides with growing scrutiny of online sales platforms, where unlicensed slimming drugs are readily accessible. Authorities are calling for stricter enforcement and public awareness campaigns to curb the trend. With no signs of abating, the NVIC’s latest figures serve as a stark reminder of the dangers posed by unregulated medical experimentation.
