State residents are getting a chance today to pick up free doses of opioid overdose antidote medication. Free naloxone will be available for pick up at more than 90 locations statewide between 11 a.m. and 7 p.m., as supplies last. Naloxone is used to fight an overdose by blocking the effects of opioids on the brain, and state officials say that more than 25-thousand Pennsylvanians have been revived by the drug since November of 2014. The medication will be offered again for free on September 25th.
