About 1:30 p.m. Friday, Waterloo police and Monroe County EMS worked together to revive a 19-year-old woman who was unresponsive following an apparent drug overdose.

Waterloo Police Chief Jim Trantham said a male subject drove the woman to the Waterloo police station — located at the back of Waterloo City Hall at 100 W. Fourth Street — in his car. Officers quickly dispatched Monroe County EMS to the police station and emergency personnel administered Narcan to the woman. She soon regained consciousness and was transported by ambulance to a St. Louis area hospital for treatment of a drug overdose.

Narcan, otherwise known as naloxone, is a prescription medicine that blocks the effects of opioids, including heroin, and reverses an overdose.

Monroe County EMS has carried Narcan for more than 20 years and administered it 10 times now over the past year. Monroe County EMS has handled 22 drug overdose calls in just the past six months alone.

Columbia EMS has carried Narcan for more than 10 years and administered it 10 times over the past year.
