Maine lawmakers approved a bill that would make it available without a prescription, but more action was needed before taking effect.
The Maine Board of Pharmacy this week agreed to raise the age limit from 18 to 21 for those seeking the drug.
Governor LePage has been a critic of naloxone, saying it serves as a crutch for drug addicts.
Democrats are now speaking out, including House Speaker Sara Gideon who said this weeks action contradicts the legislatures intent to make the drug more available, saying there's no age limit for addiction.
The Maine Democratic Party also released a statement claiming the decision was made for political purposes and that all adults should have access to the drug.
