Who can inject
MD/DO, NP/PA under physician supervision, RN under physician delegation.
Registered nurses (RNs)
Yes, under physician delegation; Ohio permits RN injection of neurotoxins and fillers with proper supervision.
Nurse practitioners & physician assistants
NP/PA may inject under physician supervision; independent practice for injectables not permitted.
The exam that makes it legal
Required; in-person exam expected before treatment. A valid order or good-faith exam by an authorized provider is what makes an injection lawful — not simply who holds the syringe.
Training expected
No state-mandated injector training beyond licensure; manufacturer training recommended.
What to verify in Ohio
Establish a written supervision agreement with a licensed Ohio physician and document all delegation protocols for RN/NP/PA injectors.
