Can a registered nurse inject Botox or filler in Washington?
Who treats · part of The Practice Perimeter
Short answer
Yes — a physician may delegate cosmetic injections to a properly trained registered nurse; if the product is used off-label the physician must be on site for the whole procedure, and if it is FDA-approved for that use, reachable within 30 minutes.
Registered nursing in Washington expressly includes executing a medical regimen prescribed by a physician, physician assistant or ARNP — and separately includes delegation. An ARNP’s expanded role is defined by the nursing board rather than by statute.

Advanced registered nursing practice means the acts of a registered nurse plus an expanded role “the scope of which is defined by rule by the board”, and on board approval an ARNP may prescribe legend drugs and controlled substances in Schedule V, and Schedules II through IV subject to statutory conditions. The statute grants the authority and hands the scope to the nursing board.
Wash. Rev. Code 18.79.050 · verified Sep 2, 2026
A physician assistant may use an LLRP device on skin with the consent of a participating physician and in accordance with standard medical practice, provided they are appropriately trained in the physics, safety and techniques of the device beforehand and remain competent for as long as it is used. Washington gives physician assistants their own rule rather than treating them as a delegate under the physician’s.

← All Washington rules and changes · MedSpaRadar is regulatory monitoring and reference: it summarizes public laws, regulations and agency actions and links each to its source. It is not legal, medical, or compliance advice, and using it creates no attorney-client relationship. A summary can lag its source or leave out detail, and monitoring itself can be interrupted — so an absence of alerts means nothing reached you, not that nothing happened.
