Can a registered nurse inject Botox or filler in Connecticut?

Short answer
Yes — at a medical spa an RN may perform cosmetic injections and soft tissue fillers, executing the medical regimen under the direction of a physician, dentist or APRN; the initial in-person patient assessment must still be done by the physician, PA or APRN.

Connecticut defines registered nursing as a list of functions — diagnosing human responses to actual or potential health problems, supportive and restorative care, health counseling and teaching, case finding and referral, collaborating in the implementation of the total health care regimen, and executing the medical regimen under the direction of a licensed physician, dentist or advanced practice registered nurse. An advanced practice registered nurse must collaborate with a Connecticut-licensed physician for the first three years after licensure, and the statute defines what that collaboration must address: consultation and referral, coverage in the nurse’s absence, a method to review patient outcomes, and disclosure of the relationship to the patient.
