An old, dangerous trend is resurfacing on teenagers' screens, causing concern among health officials once again. Poison control centers across the United States are reporting a spike in calls involving teens and Benadryl, the over-the-counter allergy medication, according to ABC News. In the first five months of 2026, reports have more than doubled compared to the same period last year, as highlighted by a fresh warning from America's Poison Centers. The culprit appears to be the revived "Benadryl Challenge," a viral social media stunt that encourages young people to take large doses of the drug in pursuit of hallucinations or a quick euphoric high.
Social Media Blamed for Trend's Return
This time, experts are not solely blaming the medication but are questioning how social media platforms continue to expose kids to risky ideas. The numbers are telling. Poison control centers handled 6,179 calls about Benadryl-only exposures among teens aged 13 to 19 in early 2026, more than double the number from the same period last year. This continues a troubling upward trend, with cases rising from 10,068 in 2024 to nearly 13,300 in 2025—an increase of almost 32% in just one year.
What Is the Benadryl Challenge?
This trend first emerged in 2020, primarily on TikTok and similar platforms. The concept is simple and highly dangerous: kids take excessive amounts of Benadryl on camera to induce a trip-like state and then share their experiences online. Medical experts, toxicologists, and the U.S. Food and Drug Administration (FDA) quickly warned that high doses could lead to extreme agitation, seizures, heart failure, or even death. Although social media companies removed the videos, the challenge never fully disappeared. It occasionally fades but resurges under different names or hashtags.
The latest spike is not due to accidental overdoses. America's Poison Centers reports that 13.2% of teen Benadryl calls in 2026 were intentional, up from 7.3% six years ago.
Why Is Benadryl Dangerous in High Doses?
Benadryl is generally safe when used as directed for allergy symptoms like sneezing, itching, and runny nose. However, excessive consumption can be extremely dangerous. The active ingredient, diphenhydramine, affects the brain and nerves strongly at high doses. Overdose can cause confusion, rapid heartbeat, frightening hallucinations, uncontrollable shaking, fainting, or worse. Doctors emphasize that these hallucinations are not enjoyable—they are often scary or disorienting. Severe cases may lead to emergency room visits for dangerous heart arrhythmias or coma.
Recent Deaths Heighten Concerns
This warning follows recent events. A few days ago, Connecticut health officials reported that three teenagers died from apparent diphenhydramine overdoses over two months. Investigators have not directly linked these deaths to the social media challenge, but the timing is concerning. For parents and doctors, the message is clear: this medication is widely available, and taking too much can be fatal. Over recent years, hospitals have reported teens being admitted to ERs, and some losing their lives, after attempting the challenge.
Expert Advice for Parents
Open and honest conversations are crucial, experts say. America's Poison Centers advises families to secure medications, monitor online trends, and discuss the dangers of misusing both prescription and over-the-counter drugs. Many teens mistakenly believe that pharmacy-bought medicines are harmless, but large doses can be dangerous. Parents should also pay attention to what their children view online. If a viral challenge emerges, bring it up calmly. The best approach is calm honesty rather than scare tactics. Let teens know that such social media stunts are not just pranks—they can lead to hospitalization or worse.
The bottom line: Benadryl is safe when used correctly, but taking a handful of pills is not a shortcut to fun. It is a shortcut to the emergency room.
