Can a registered nurse inject Botox or filler in Louisiana?

Short answer
The cited rules do not settle this — they only define an advanced practice registered nurse as an RN nationally certified in an advanced specialty. Nothing cited states whether an RN may inject neurotoxin or filler, or on what physician delegation terms.

Louisiana defines the advanced practice registered nurse by national certification plus board criteria: an APRN is a licensed registered nurse certified by a nationally recognized certifying body, such as the American Nurses Credentialing Center, as having an advanced nursing specialty described in the Part, and who meets the criteria for an APRN established by the board. Where no national certification examination exists in a selected clinical area, the board may establish commensurate requirements. The definition then names the roles it includes — among them the certified nurse midwife, educated in the disciplines of nursing and midwifery and authorized to manage nurse midwifery care in the antepartum, intrapartum, postpartum and gynecological periods, and the certified registered nurse anesthetist, educated in the field of nurse anesthesia and certified to the requirements of a nationally recognized certifying body. Because the operative criteria are set by the BOARD, these claims do not fix the scope of any particular procedure.
