Multiple Fentanyl Overdoses — New Haven, Connecticut, June 23, 2016

Summary

What is already known about this topic?

Fentanyl and its analogs have been substituted for heroin and other opioids, and are usually marketed to persons seeking opioids. Because of fentanyl’s high potency compared with heroin, methadone, and oxycodone, there is a high risk for fatal overdose associated with illicit use. Higher than normal doses of the opioid antagonist naloxone might be required to reverse fentanyl overdose.

What is added by this report?

On June 23, 2016, fentanyl marketed as cocaine resulted in an extraordinary opioid overdose outbreak in New Haven, Connecticut, resulting within 6 hours in at least 12 cases, marked by four intensive care unit admissions and three deaths. A rapid and coordinated public health response involving multiple partners likely reduced the impact of this outbreak.

What are the implications for public health practice?

A collaborative and timely multi-organization response can mitigate the consequences of an extraordinary public health event. Development and implementation of a screening test for fentanyl might inform clinicians about the presence of these particularly deadly opioids and prevent deaths. Opioid use education and naloxone administration kits and education should be extended to all persons at risk for illicit drug use, their families, and friends.
