DENVER — A life-saving opioid antidote is getting into more hands in Colorado at a time of urgent need across the state and the country.

On Wednesday, Boulder County authorities confirmed another death from a heroin overdose in Colorado, but hope is beginning to grow as use of an important opioid antidote continues to increase.

Naloxone, also known by its brand name Narcan, can stop an overdose and save a life within minutes.

Naloxone has been available to medical professionals for years, but in the past year, the Denver Fire Department, the Denver Police Department and many others have begun carrying it and administering it.

Denver’s Harm Reduction Action Center has pushed for increased access to Naloxone for years and the agency has also trained volunteers on how to use it. Since 2012, the action center has trained more than 800 people and saved more than 330 lives.

Now, a new interactive map is showing where those volunteers’ saves have taken place across the metro area. The map also offers a startling look at where overdoses hit hardest in the past four years.

According to the latest number from the Denver Fire Department, firefighters have successfully used Naloxone to reverse an overdose more than 50 times since they began carrying it in April 2015.

“This is just a Band-Aid for what is a larger problem,” Denver Fire Department Lt. Greg Pixley said.

According to the Centers for Disease Control and Prevention, Colorado overdose deaths have risen 60 percent in the past 12 years, driven by opioid abuse, including heroin and prescription painkillers. By 2014, overdose deaths surpassed traffic deaths in Colorado.

“This opiate abuse, it’s not just focused on us urbanites,” Pixley said. “It’s focused across the United States, suburban areas and rural areas.”
