AUGUSTA, Maine — A bill that would allow the overdose antidote Naloxone to be sold without a prescription is gaining support in the Maine Legislature, but there may not be enough votes to survive an expected veto by Gov. Paul LePage.

On Thursday, the Senate voted 25-8 and the House voted 98-49 to pass a bill that will allow pharmacists to provide the antidote to those suffering from heroin addiction and family members.

Supporters said easing access to the drug would save lives, but opponents said it would enable heroin users to take greater risks.

Additional votes are needed to send the bill to LePage, who opposes increasing access to Naloxone. A two-thirds majority in both chambers is required to override a veto. An override vote would be close in both chambers.
