Who can inject
MD/DO, NP/PA under physician supervision, RN under physician delegation.
Registered nurses (RNs)
Yes, under physician delegation; RN must inject under standing orders or protocols from a supervising physician.
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 mandatory before injectable 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; however, physician-approved delegation and protocol documents are required.
What to verify in Ohio
Establish a formal physician medical director agreement and ensure all injectable protocols are documented and approved by the medical director before operations begin.
