The 'Benadryl Challenge' is a dangerous social media trend that has landed two Lancaster County teenagers in the ICU with potentially life-threatening conditions. This challenge involves ingesting a high dose of diphenhydramine, an over-the-counter medication used to treat allergies and cold symptoms, to induce hallucinations. The usual adult dose is two capsules, but the challenge encourages participants to take up to 12 tablets at once, leading to overdose and serious health risks.
Dr. Pia Fenimore, a pediatrician, confirms that two children have been admitted to the hospital with anticholinergic poisoning, a result of excessive diphenhydramine intake. The challenge involves videoing and posting the reaction on social media, which is highly concerning. The cholinergic system, responsible for regulating memory, learning, and attention, is negatively impacted by high doses of diphenhydramine, leading to cardiac arrest, coma, and seizures.
The trend emerged in 2020 and has seen a concerning rise in recent years. Calls to poison centers regarding diphenhydramine for 13- to 19-year-olds increased by 32% from 2024 to 2025, and the first half of 2026 saw nearly double the number of diphenhydramine-related calls compared to the same period in 2025. This alarming trend highlights the need for increased awareness and education among parents and children.
Dr. Fenimore emphasizes the importance of parents discussing the Benadryl challenge and the misuse of over-the-counter medications with their children. She also recommends that parents monitor their children's social media activities and engage with the platforms themselves to stay informed. The challenge's popularity during the summer months, when children have more free time, adds to the risk.
The consequences of an overdose can be severe and long-lasting. Seizures can cause brain damage, affect vision and hearing, and cardiac arrest can lead to long-term complications. The nervous system's inability to recover quickly from such damage is a significant concern. This trend underscores the importance of parental vigilance and open communication with children about the dangers of social media challenges and medication misuse.
In conclusion, the 'Benadryl Challenge' is a dangerous trend that requires immediate attention and action. Parents and caregivers must take proactive steps to educate themselves and their children about the risks associated with this challenge and other potential dangers on social media. By staying informed and involved, we can help prevent serious harm to young people.
