Netherlands sees doubling of poisoning cases linked to weight-loss injections

The number of poisoning cases associated with weight-loss injections in the Netherlands has nearly doubled in 2025, reaching 149 compared to 76 in 2024, according to data from the National Poisons Information Center. Public health officials caution that this figure might be an undercount, as not all poisoning incidents are reported.

A substantial portion of these cases, approximately 40%, stem from individuals obtaining the injections without a prescription or medical supervision. Experts express concern over the expanding market for these drugs acquired through informal channels, highlighting a shift from medically supervised use to self-administration.

This transition significantly elevates the risk of incorrect dosages and adverse side effects. Specialists warn that improper use can trigger acute symptoms requiring immediate medical attention. Furthermore, there is a potential for long-term harm to the liver, kidneys, and nervous system.
