Ottawa-Area Families Put on Alert as Dangerous Drug Challenge Makes a Comeback
Ottawa parents, it's time to have a hard conversation with your kids — a dangerous social media trend is back, and Ontario communities are already sounding the alarm.
Nipissing First Nation in Ontario has issued an urgent public alert after reports emerged that young people are once again deliberately taking large doses of Benadryl (diphenhydramine), a common over-the-counter allergy medication, in a bid to induce hallucinations. The so-called "Benadryl Challenge" has been circulating on TikTok, encouraging teens to take dangerously high amounts of the drug to experience a "trip."
What Is the Benadryl Challenge?
The challenge originally went viral on TikTok several years ago and was linked to multiple hospitalizations and deaths across North America. Health authorities and social media platforms took action to suppress it — but like many dangerous online trends, it has resurfaced.
At high doses, diphenhydramine — the active ingredient in Benadryl — can cause hallucinations, rapid heart rate, seizures, confusion, and in severe cases, death. What makes this especially alarming is how easily accessible the medication is. It's sold at virtually every pharmacy and grocery store in Canada, including right here in Ottawa, without a prescription.
A Real and Present Danger for Ontario Youth
Nipissing First Nation's alert is a sobering reminder that this isn't a distant problem. The community, located roughly three hours from Ottawa, reported that some youth had been participating in the challenge, prompting local health officials to warn parents and caregivers directly.
Health Canada and poison control centres have previously flagged diphenhydramine overdose as a medical emergency. Symptoms can escalate quickly and may require immediate hospitalization. A "safe" dose of Benadryl for adults is typically 25–50 mg — the challenge encourages taking many times that amount.
What Ottawa Parents Can Do Right Now
Experts recommend a few key steps for families in the Ottawa region:
- Talk openly with your kids about the challenge and why it's dangerous — shame and secrecy make these situations worse
- Check your medicine cabinet and consider storing Benadryl and similar antihistamines out of easy reach
- Monitor social media activity where possible, but prioritize dialogue over surveillance
- Know the signs of overdose: extreme drowsiness, confusion, rapid heartbeat, difficulty urinating, flushed skin, or hallucinations — call 911 immediately if you suspect an overdose
If you're in Ottawa and concerned about a potential overdose, contact the Ontario Poison Centre at 1-800-268-9017 (available 24/7) or call 911 for emergencies.
A Bigger Conversation About Social Media and Teen Health
This latest alert is part of a growing pattern of social media challenges that put young people's lives at risk. Ottawa Public Health and school boards across the region have previously issued guidance on how to address viral challenges with youth, emphasizing that open, non-judgmental conversation is the most effective tool.
Don't wait for a school newsletter to bring this up — tonight is a good time to start the conversation.
