Can a physician assistant inject or prescribe in Texas?
Who treats · part of The Practice Perimeter
Short answer
Yes — a PA may perform injections and prescribe as services delegated by a supervising physician, within the PA's training and delineated by the physician's protocols; prescribing also requires a separate written prescriptive authority agreement.
Texas defines the physician assistant’s practice as delegated practice, and the injection sits inside it. “The practice of a physician assistant includes providing medical services delegated by a supervising physician that are within the education, training, and experience of the physician assistant.” The enumerated services include “ordering or performing diagnostic and therapeutic procedures” and “prescribing or ordering a drug or device as provided by Subchapter B” of Chapter 157. The relationship is stated as agency: “A physician assistant is the agent of the physician assistant’s supervising physician for any medical services that are delegated by that physician” and that “are delineated by protocols, practice guidelines, or practice directives established by the supervising physician”.

Prescribing takes a separate written instrument, and the physician’s side of it is capped. “a physician may delegate to an advanced practice registered nurse or physician assistant, acting under adequate physician supervision, the act of prescribing or ordering a drug or device as authorized through a prescriptive authority agreement” between them. “the combined number of advanced practice registered nurses and physician assistants with whom a physician may enter into a prescriptive authority agreement may not exceed seven”, or their full-time equivalent — a limit that does not apply to a practice serving a medically underserved population or to a facility-based practice.

A registered nurse who is not an APRN (and an LVN) may not perform medical diagnosis or prescribe, but may carry out a delegated medical act — such as administering a cosmetic injection ordered by an appropriately licensed practitioner — when the Board of Nursing’s criteria are met: documented competency/education, written policies and guidelines, an order from an appropriate licensed practitioner, and available medical and nursing support.
