BANGOR, Maine — Bangor police officers used newly supplied Narcan twice over the Fourth of July weekend, reviving two individuals who were suffering from suspected drug overdoses, according to police officials.

“These are the first two instances where we have used Narcan since training everyone and distributing it,” Bangor police Chief Mark Hathaway said in an email to city officials Tuesday morning. “It works.”

Narcan is a brand name for the drug naloxone, which acts as an antidote to opioid overdoses.

Around 5 p.m. Friday, first responders were dispatched to a Hammond Street apartment after a suspected overdose, Hathaway said. An officer found an unconscious man on the floor, not breathing. The officer administered nasal Narcan spray, and the patient began to breathe again and show signs of recovery. The patient was taken to the hospital by a city ambulance.

Saturday afternoon, an officer was dispatched to the parking lot in front of Marshall’s at the Airport Mall. The woman had no pulse. The responding officer administered Narcan, and the woman quickly recovered. EMTs arrived soon after, but the woman refused further treatment and left, Hathaway said.

Police officials declined to release additional information about these incidents Tuesday.

Bangor’s police officers were trained to administer Narcan by Penobscot Community Health Care officials in May, shortly before the spray was put into police cruisers.

One of the recommendations from the community working group, which formed two years ago to come up with ways to combat growing drug abuse problems in the region, was to ensure Narcan is available to first responders.

The Bangor City Council gave Hathaway approval in early May to collaborate with PCHC to get Narcan into officers’ vehicles.
