Who holds it
- Physicians (MD/DO): full prescriptive authority.
- Nurse practitioners: the Arizona definition of a nurse practitioner in A.R.S. § 32-1601 includes prescribing, administering and dispensing therapeutic measures, including legend drugs, devices and controlled substances, within NP scope and on meeting the Board's requirements.
- Physician assistants: prescribe within their authorization and the physician relationship the PA board rules require.
- Registered nurses and estheticians: do not hold prescriptive authority.
Controlled substances
Prescribing controlled substances also requires federal DEA registration and state authorization. This matters for testosterone and certain other therapies in hormone practices.
Why it matters in aesthetic practice
Prescription treatments such as neuromodulators and many hormone therapies need an order from someone with prescriptive authority. That is why a good-faith exam and written provider order come from a prescriber, and why RNs perform treatments only through delegation.
How it shows up in aesthetics
Because neuromodulators and fillers are prescription products, prescriptive authority is part of every treatment, either held by the injector or provided through a prescriber’s order. What each license may prescribe differs by state and license type.
Common mistakes
- Assuming every licensed provider can prescribe.
- Using an order that does not cover the treatment performed.
- Not checking current board rules for your license.
Frequently asked
Can an RN prescribe in Arizona aesthetic practice?
No. RNs may carry out treatments under a prescriber's order but do not hold prescriptive authority.
Does prescriptive authority cover every drug?
No. It operates within the provider's scope and conditions. Controlled substances require additional registration.
