Background Poisonings are a common reason for consultation, yet long-run large-scale French epidemiology is scarce. The Lille Poison Control Centre’s historic CIGUE database, curated from 1988 to 2020, offers a 33-year window on exposures across ages and contexts. Aim To improve primary care prevention by characterising trends, risk groups, and substances in cases reported to the Centre, using indicators aligned with international studies. Method Retrospective descriptive analysis (1988–2020) of the CIGUE ( Centrale d’Informations et de Gestion en Urgences des Empoisonnements ) database (SQL extraction). Age, circumstances, and substances were mapped to identify trends and emerging risks. Results Among 662 179 cases, calls increased until 2013. Children aged 1–5 years were most affected (46.6%). Circumstances were dominated by domestic accidents (67.9%), followed by suicidal ingestions (12.7%), and therapeutic errors (12.1%). Suicidal poisonings mainly involved adolescents (56% in those aged 13–20 years). Domestic accidents remained stable, mostly in children. Frequent substances were household detergents (9.1%), benzodiazepines (7.3%), and paracetamol (5.7%). Detergent exposures were almost exclusively accidental (65.8% for those aged <5 years; 91.8% accidental). Benzodiazepines and paracetamol were often linked to suicidal intent. Over time, domestic accidents remained stable, while adolescent suicidal poisonings persisted and therapeutic errors rose steadily. Opioid exposures increased nearly fourfold, mostly with suicidal intent (48.6%). Most cases were asymptomatic or mild; severe/fatal cases were <1% ( n = 574 deaths). Conclusion This is the largest longitudinal poisoning study in France. It reveals enduring paediatric domestic risk, sustained adolescent self-harm, and a rising opioid signal. Insights can guide GPs’ anticipatory guidance, safe-use counselling, and early intervention.
