Three Connecticut Children Die After Apparent Diphenhydramine Overdoses; Officials Urge Parents To Secure Medications

Connecticut authorities confirmed that three children have died in the past two months from apparent overdoses involving diphenhydramine, an over-the-counter antihistamine sold under brand names such as Benadryl. The Connecticut Office of the Child Advocate (OCA) said it is coordinating with the Connecticut Department of Public Health (DPH) to raise awareness about medication safety and prevention strategies.

OCA: “OCA can confirm that three children have died due to apparent diphenhydramine overdose in the last two months.”

DPH and OCA have issued guidance to treatment providers and clinicians urging conversations with parents and caregivers about safe storage and the dangers of medication misuse. Officials emphasize prevention and early intervention as priorities while investigations continue.

Unclear Link to Social Media Challenge

The OCA said it has received media inquiries about a possible connection to the so‑called "Benadryl Challenge" promoted on social media, but it cannot confirm that the recent deaths are linked to that trend. Regardless, the agency warned that adolescents may be tempted to misuse medications and advised parents to remain vigilant.

Medical Risks and Federal Warning

Diphenhydramine is widely used to relieve allergy and cold symptoms when taken as directed. However, the U.S. Food and Drug Administration (FDA) warned in a 2020 Drug Safety Communication that excessive doses can cause "serious heart problems, seizures, coma, or even death." The FDA previously noted reports of teenagers being hospitalized or dying after taking large amounts of diphenhydramine following encouragement from social media videos.

Mental Health And Prevention

Officials also urged families to seek help if children are experiencing mental‑health struggles. The OCA noted that, across Connecticut, about 17 children present to emergency departments each day for self‑harm or suicidal ideation. Resources are available for families, and clinicians are encouraged to provide or refer for mental‑health support.

Health and addiction experts echo the call for open conversations about medication safety. The nonprofit Partnership to End Addiction warns that challenges encouraging large doses of diphenhydramine can lead to severe side effects including nausea, seizures and death.

What Parents And Caregivers Should Do

• Store Medications Securely: Keep all prescription and over‑the‑counter medicines locked or out of reach.
• Talk With Teens: Discuss the dangers of misusing medications and monitor social media activity for harmful trends.
• Know The Signs: Seek immediate medical help for suspected overdose (difficulty breathing, seizures, loss of consciousness) and urgent mental‑health care for self‑harm risk.
• Engage Providers: Ask pediatricians and school counselors about prevention resources and local supports for mental health.

Authorities continue outreach to treatment providers and families to prevent further tragedies and to raise awareness about safe storage and available mental‑health resources.
