BUFFALO, N.Y. -- The opioid overdose antidote naloxone, often known under the brand name NARCAN, is now less expensive to purchase for a lot of people in New York State.

A first-of-its-kind initiative, called the Naloxone Co-payment Assistance Program, or N-CAP, started Wednesday. It offers up to $40 in co-pay assistance for people with insurance -- whether it's from an employer, the marketplace, Medicaid or Medicare -- to purchase naloxone from a pharmacist.

You would need to purchase the medicine at a pharmacy with a "standing order", which means the medicine can be purchased there without a prescription. The state maintains a directory of all those pharmacies. It can be found here.

Those without insurance or with no prescription coverage can still get naloxone for free by contacting one of the Registered Opioid Overdose Programs.

Erie County leaders have been encouraging people to purchase naloxone at the pharmacy so that the county can use its supply for first responders and those who truly cannot afford it.
