Pensacola clinician warns: Benadryl challenge returns online, threatening teens’ health

A Pensacola physician warns that the 2020 Benadryl Challenge is resurfacing online, encouraging teens to ingest large amounts of allergy medicine to induce hallucinations, a practice linked to dangerous symptoms like racing hearts and cardiac arrhythmias, potentially leading to cardiac arrest or death; officials note cases in Connecticut and reports of related symptoms locally, and doctors urge locking away all medications and seeking emergency care if overdose is suspected.
