A Quebec coroner is recommending that diphenhydramine—an antihistamine and sedative sometimes used to sleep better—should be better managed in pharmacies after the overdose death of an 18-year-old man south of Montreal in December 2023.
The young man, whose identity is not revealed in the report made public, died of acute diphenhydramine poisoning at his home in St-Mathias-sur-Richelieu.
