A 15-year-old Oklahoma girl remains in intensive care with no brain activity after overdosing on Benadryl while participating in a viral TikTok challenge that encourages teens to ingest large amounts of the over-the-counter allergy medication. Leah Presson, 15, was hospitalized at Integris Health Baptist Medical Center in Oklahoma City after experiencing seizures and cardiac arrest, her family told KFOR.
The "Benadryl Challenge" first emerged during the COVID-19 pandemic as a trend where teenagers film themselves consuming toxic amounts of diphenhydramine—the active ingredient in Benadryl—to induce hallucinations. The FDA issued a public warning about the challenge in 2020, stating it was aware of reports of teenagers ending up in emergency rooms or dying after participating.
What the Right Is Saying
Conservative critics of new online safety regulations say the focus should remain on parental responsibility and personal accountability rather than government intervention in social media content moderation. Republican lawmakers have pushed back against legislation they characterize as government overreach that would infringe on free expression rights.
"Parents need to be engaged with their children about the dangers of following internet trends," said a spokesperson for Sen. Marsha Blackburn, R-Tenn., who has opposed age verification bills. "This is ultimately about families taking responsibility, not the federal government monitoring what teenagers see online."
Richard Presson, Leah's father, echoed calls for greater awareness and education rather than new regulations in an interview with KFOR. "I just want everybody to be aware of where they can educate their kids, but these challenges are just silly, and they need to be educated so it doesn't happen again," he said. He noted that Leah had participated in the challenge before, prompting him to warn other parents about monitoring their children's online activity.
What the Left Is Saying
Democratic lawmakers and child safety advocates say the case underscores the need for stronger federal regulation of social media platforms that host dangerous content targeting minors. Senate Democrats have repeatedly called for legislation requiring TikTok and other platforms to implement more robust safeguards against harmful challenges, arguing that self-regulation has proven insufficient.
"This is exactly what we warned about," said Sen. Richard Blumenthal, D-Conn., in a statement referencing prior hearings on youth safety online. "Platforms must be held accountable when their algorithms amplify content that puts children at risk. Parents cannot monitor every video their child watches."
The Connecticut Office of the Child Advocate, which previously issued a warning after three children in the state died from Benadryl overdoses linked to the challenge, pointed to systemic gaps in platform moderation. "We strongly encourage parents to store all medications safely, to ensure they are not easily accessible to children," the office stated. The agency has called for increased public health messaging and digital literacy programs in schools.
What the Numbers Show
Benadryl (diphenhydramine) is an antihistamine used to relieve cold and allergy symptoms including runny nose, sneezing, watery eyes, hives, skin rash, and itching. According to poison control data, antihistamine overdoses consistently rank among the top 10 most common exposures reported to U.S. poison control centers annually.
The FDA's 2020 warning about the Benadryl Challenge stated: "We are aware of news reports of teenagers ending up in emergency rooms or dying after participating in the 'Benadryl Challenge' encouraged in videos posted on the social media application TikTok." The agency urged parents and healthcare professionals to be vigilant.
At least four deaths among children have been linked to the challenge in recent months: three in Connecticut, according to prior reporting by this outlet, and an 11-year-old Oklahoma girl identified as Molly Miller earlier this year. Searches for "Benadryl Challenge" or related terms on TikTok now display a drug and alcohol safety warning when attempted.
The Bottom Line
The case of Leah Presson highlights ongoing tensions between tech platform responsibility and parental oversight in protecting minors from viral dangerous trends. Advocates for stronger regulation argue that platforms possess the algorithmic tools to identify and suppress harmful challenges before they spread widely, while opponents maintain that content moderation cannot substitute for family involvement.
TikTok has stated it removes content promoting dangerous acts and directs users to crisis resources when relevant searches are detected. However, critics note that by the time such safeguards activate, viral challenges may have already circulated among teenage audiences with tragic consequences. What happens next for Leah Presson's family—and whether this case accelerates legislative action on youth online safety—remains to be seen.
