US IV therapy rules are a patchwork. 36 states still lack any dedicated medspa oversight regime (AMA, 2024). Texas became the first state to write IV-specific scope rules after Jenifer Cleveland died at a San Antonio medspa in 2023 (Holland & Knight, 2025). This ranking sorts 10 states from strictest to loosest. Rules change. Verify with the state board.
Disclaimer: Informational only, not legal advice. IV therapy regulations change often, and enforcement varies by state board. Consult a licensed healthcare attorney in your state.
What we looked at
Ranking criteria — each state scored on five dimensions:
- Who may administer an elective IV (MD, PA, APRN, RN, LPN/LVN, MA)
- Who may prescribe or order the IV
- Physician supervision model (on-site, on-call, written protocol only)
- Ownership rules (corporate practice of medicine doctrine strength)
- Recent statutory or regulatory action (2024–2026)
Stricter = fewer eligible administrators, tighter supervision, narrower ownership. Looser = broader delegation, weaker CPOM enforcement, fewer reporting duties.

Tier definitions: Strictest = administrator list narrows; LVN/LPN/MA barred from IV. Strict = administrator list narrows but LPN allowed with certificate. Moderate = standard nurse delegation rules apply. Loosest = broad delegation, fewer specific IV statutes.
1. Texas — strictest after Jenifer's Law (Sept 1, 2025)
Administrators: MDs, PAs, APRNs, RNs only. Prescribers: physicians, delegated PAs/APRNs. Supervision: physician delegation under the Texas Medical Practice Act.
Texas House Bill 3749 took effect Sept 1, 2025. It is the first state IV-specific scope statute (Nurse.org, 2025). The law followed Jenifer Cleveland's 2023 death after a TPN drip at Wortham Med Spa. The administrator list is closed. LVNs, who once ran many medspa drips, lost that authority overnight (Frier Levitt, 2025). Cosmetic-only medspas without IV are largely untouched.
2. Florida — physician-owned, bi-weekly medical director visits
Administrators: physicians, NPs, PAs, RNs by delegation. Prescribers: MD or DO only. Supervision: written delegation and standing orders; medical director must visit every 14 days.
Florida treats IV therapy as a medical procedure that must occur under physician supervision (Portrait, 2026). Some practice areas require board-certified dermatology or plastic surgery training for the medical director.
RNs may push IV under delegation and within their licensed scope (Phorest, 2026). The physician keeps legal responsibility for every delegated task. The bi-weekly site visit is the practical sting. Travel medspa chains find it hard to scale.
3. California — standardized procedures gate the RN IV bar
Administrators: RNs under standardized procedures (Title 16 CCR §1379); LVNs only with BVNPT-approved IV certificate. Prescribers: physicians and NPs. Supervision: medical corporation required — no CPOM exception.
California's Nursing Practice Act lives in BPC §2700 and following (CA BRN, 2025). For elective wellness drips, RNs operate under standardized procedures — written protocols authorizing IV fluids, vitamins, and emergency response (Bay Legal, 2025). The Board requires protocol review at least every three years.
LVNs may administer IVs only after a BVNPT-approved IV therapy and blood withdrawal course (LegalClarity, 2025). Even with the certificate, LVNs cannot push IV medications or start IVs on neonates.
4. New York — IV therapy is the practice of medicine
Administrators: physicians, NPs, PAs, and RNs/LPNs with formal IV training. Prescribers: physicians and NPs. Ownership: MD-owned or Professional Corporation only.
New York's Department of Education is clear: IV hydration is the practice of medicine and must happen in a professional medical office (Lengea, 2025). Corporate practice of medicine is enforced — a regular LLC or Inc. cannot employ physicians (Stevens & Lee, 2025).
RNs and LPNs may push IV only after formal IV training and documented competency (NYSBON, 2025). LPNs cannot insert/remove central venous access devices or push IV drugs through them. Medical assistants are unlicensed in New York and cannot start IVs.
5. New Jersey — direct supervision and physician exam before delegation
Administrators: physicians, RNs, PAs, certified LPNs. Prescribers: physicians, NPs, PAs. Supervision: direct (physical presence or real-time audio/video).
New Jersey limits IV administration to physicians, RNs, PAs, and certified LPNs (Post & Schell, 2025). Medical assistants cannot start or push IVs even under direct physician supervision. The supervising MD, APN, or PA must be immediately available on the premises or via real-time audio/video (Greenbaum, 2025).
RN aesthetic scope is narrower than NP or PA — RNs work under a detailed, physician-signed protocol (MedSpire, 2026). Telehealth-only medical director arrangements may not satisfy the direct-supervision rule.
6. Massachusetts — 244 CMR 3.05 governs every delegation
Administrators: licensed medical professionals; RNs/PAs by delegation. Prescribers: physicians and independent NPs. Supervision: medical director is MD or independent NP.
Massachusetts confines IV hydration and injectables to licensed medical professionals (Portrait, 2026). The Board of Nursing's 244 CMR 3.05 controls delegation. Only licensed nurses may delegate nursing care, and the delegating RN keeps full responsibility (Mass.gov, 2025). Independent NPs may serve as medical director. That is unusual — most strict-tier states require MD or DO only.
7. Washington — full-practice NP authority, rules still settling
Administrators: physicians, NPs, trained RNs under protocol. Prescribers: physicians and NPs (full practice authority). Ownership: NP-owned clinics permitted; CPOM not strictly enforced.
Washington is a full-practice authority state for NPs (Opportunity Healthcare, 2025). NPs can prescribe and administer cosmetic injectables without physician supervision. They can own medspas.
IV hydration counts as medication. A medication order is required before the drip starts. The Washington DOH continues to study IV and microneedling rules (WA DOH, 2025). Final rulemaking has not closed. Non-physicians may own a medspa with a designated MD medical director.
8. Colorado — delegation by protocol, HB 1024 added disclosure
Administrators: physicians, NPs, RNs by written protocol. Prescribers: physicians and NPs. Supervision: off-site delegation allowed with written emergency protocols. Ownership: physician-owned (CPOM enforced).
Colorado physicians may delegate IV to qualified RNs through written orders or standing protocols (Optimantra, 2025). With adequate written emergency protocols, on-site presence is not always required (Portrait, 2025). That is looser than New Jersey's direct-supervision standard.
The 2025 HB 1024 law forced new disclosures. On-site signage, online disclosure, and patient consent must name when an unlicensed person performs the delegated procedure.
9. Nevada — CPOM enforced, MD within 30 minutes
Administrators: physicians, APRNs, RNs by order. Prescribers: physicians, PAs, dentists, podiatric physicians, APRNs. Supervision: physician must be reachable by phone and ≤30 minutes from the treatment site.
Nevada defines IV therapy as infusion at a regulated rate prescribed by a licensed physician, PA, dentist, or podiatric physician (NV Legislature). RNs take orders only from those prescribers or an APRN. When physicians delegate IV to RNs, the physician must be reachable by phone and within 30 minutes of the site (AmSpa, 2024).
Nevada enforces corporate practice of medicine — only physicians and NPs can own a medical or professional nursing practice (Lengea, 2025). Mobile IV trucks must track physician proximity in real time.
10. Arizona — broadest delegation, MA injections allowed
Administrators: physicians, NPs, PAs, RNs by delegation; MAs may inject under direct supervision. Prescribers: physicians, NPs, PAs. Supervision: direct for MAs; delegation for RNs.
Arizona is the most permissive state on this list. RNs run IV therapy under physician, NP, or PA orders within scope (Medical Director Co., 2025). Medical assistants may take body fluid specimens and give injections under direct MD, PA, or NP supervision (Arizona R4-18-605). Few states permit this for MAs.
The 2025 HB 2025 expanded MA scope to general supervision for certain tasks. IV administration was not added. Operators must still keep a written delegation matrix and procedure-specific consents.
Bottom line
The legal floor rises every year. Texas wrote the first IV-specific scope statute in Sept 2025. New York ran 223 medspa inspections in 2024 and cited 87 clinics (MedSpire, 2025). Strict states close the administrator list and enforce CPOM. Loose states lean on broad nursing delegation. Operators in moderate or loose states should plan for tightening. Jenifer's Law set the precedent.

Frequently asked questions
Can an RN run IV therapy independently? Not in any of the 10 states ranked here. Every state requires a physician — or, in NP full-practice states, an NP — to write the order or protocol. RNs administer; they do not prescribe wellness IV on their own license.
Do medspas need an MD on site? Depends on the state. Florida requires bi-weekly site visits. Nevada requires the MD within 30 minutes of the treatment site. New Jersey demands direct supervision. Colorado allows off-site delegation when written emergency protocols exist.
Can LVNs or LPNs administer IV therapy? Texas barred LVNs in 2025. California permits LVN IV only after a BVNPT-approved certificate and never IV push. New York and New Jersey require IV-specific certification with supervision.
Is IV therapy the practice of medicine? Yes, in states that have addressed the question. New York, Florida, Nevada, and Colorado treat IV hydration as a medical act. That triggers CPOM rules and can bar non-physician ownership.
What was Jenifer's Law? Texas HB 3749, effective Sept 1, 2025. It closed the administrator list to MDs, PAs, APRNs, and RNs after Jenifer Cleveland died at a San Antonio medspa from a TPN drip (Holland & Knight, 2025).
