Several reports describe a case involving a viral online trend sometimes referred to as the “Benadryl Challenge,” in which people attempt to take large doses of diphenhydramine, an antihistamine found in products such as Benadryl. According to coverage from Newsweek and NDTV, a 15-year-old identified as Leah Presson is hospitalized after attempting the challenge. The reports state that she has experienced severe neurological injury, with clinicians describing “zero brain activity,” and that she is critically ill. Both outlets frame the incident in the context of a viral social media trend and emphasize that the attempt leads to life-threatening effects. Neither source provides extensive additional details about the circumstances of the attempt, the exact amount taken, or the timeline beyond noting that she tried the trend and subsequently required urgent medical care. The reports collectively highlight the risk associated with misinformation or challenges that encourage unsafe dosing of medications without medical supervision.
