Training & certification expected

No state-mandated injector training beyond licensure.

The license that lets you inject

MD, DO, NP, PA, RN under physician supervision

If you’re an RN

Yes, under physician delegation and supervision

Why the order still matters

Required; in-person exam before treatment Training gets you the skill; a valid order or good-faith exam is what keeps the treatment lawful.

What to verify in Maine

Establish a written physician-supervision agreement and ensure the medical director is licensed in Maine and actively involved in protocol development and oversight.
