The company behind a life-saving opioid overdose drug faces criticism over a major price hike.
The Evzio drug is a form of Nalaxone, which temporarily reverses the effects of an overdose.
In 2014, the drug cost $700. Now it has jumped 500 percent to $4,500.
Emergency crews across the country -- including those in Tucson -- are stocking up on the drug to treat overdoses.
Tucson Fire and police use a different form of the drug -- Narcan.
