What Training Do You Need to Inject Botox in Missouri?

Missouri doesn't hand the syringe to just anyone. Here's the license, the training, and the supervision that Missouri expects before you can inject.

By Evan at Inside MedSpa

Training & certification expected

No state-mandated injector training beyond licensure.

The license that lets you inject

MD/DO, NP/PA with physician supervision, RN under physician delegation

If you’re an RN

Yes, under physician delegation; specific training/protocols required

Why the order still matters

Required; in-person or telehealth allowed for established patients Training gets you the skill; a valid order or good-faith exam is what keeps the treatment lawful.

What to verify in Missouri

Confirm your medical director's scope and ensure written delegation protocols for all injectors are documented and board-compliant.
