Deliberate self-poisoning in four European countries: retrospective analysis of poison centre data

Results:
Within six years, poison centres reported 1,783,858 cases, and one in ten (177,921 cases) involved deliberate self-poisonings. Rates varied across countries, ranging from 8% in France to 23% in the Netherlands. Cases with deliberate self-poisoning remained stable between 2017 and 2020, with an increase observed from 2021 to 2022. Females accounted for 70% of cases, rising to 84% among children/adolescents of 5-17 years. Rates among children/adolescents of 5-17 years increased significantly after 2020 in all countries, largely due to a strong increase among females. Substances involved varied by country, but alcohol, benzodiazepines, and antidepressants dominated in adults, while paracetamol and ibuprofen dominated among children/adolescents of 5-17 years.
Discussion:
Common trends in deliberate self-poisoning, particularly in different age groups, are highlighted and challenges of cross-national data harmonisation in European poison centres are demonstrated.
Conclusion:
Deliberate self-poisoning represented a substantial proportion of poisoning cases, with a sharp rise after 2020, especially among children/adolescent females using readily available over-the-counter non-prescription medicines. These findings underscore the need for targeted prevention strategies and demonstrate the value of coordinated data collection. Expanding collaboration across additional countries could enhance monitoring, strengthen trend analyses, and inform public health interventions.

Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
