States Where Nurse Practitioners Can Prescribe Ketamine

In many states, nurse practitioners (NPs) can prescribe ketamine — including through telehealth — as long as they hold the proper licensing and DEA registration, and the prescription follows state controlled-substance and telemedicine rules. Whether an NP can do this independently depends on each state's scope-of-practice law. About half of U.S. states grant NPs "full practice authority," letting them evaluate, diagnose, and prescribe without physician oversight. The rest require some form of physician collaboration or supervision. Because ketamine is a Schedule III controlled substance, additional federal and state rules also apply.

States where nurse practitioners can prescribe ketamine via telemedicine

There is no separate "ketamine list." An NP's ability to prescribe ketamine via telemedicine generally follows their state's broader scope-of-practice and controlled-substance laws. The clearest path exists in full practice authority (FPA) states, where NPs can prescribe controlled substances on their own license.

States and territories that grant NPs full practice authority generally include Alaska, Arizona, Colorado, Connecticut, Delaware, Hawaii, Idaho, Iowa, Kansas, Maine, Maryland, Massachusetts, Minnesota, Montana, Nebraska, Nevada, New Hampshire, New Mexico, North Dakota, Oregon, Rhode Island, South Dakota, Utah, Vermont, Washington, Wyoming, and the District of Columbia. Several other states, such as New York and Florida, have expanded NP authority under certain conditions like a minimum number of supervised practice hours.

Scope-of-practice laws change regularly, so always confirm current rules with your state's board of nursing before assuming an NP can prescribe independently in your state.

Full, reduced, and restricted practice explained

The American Association of Nurse Practitioners groups states into three categories:

Practice level	What it means for prescribing
Full practice	NPs may evaluate, diagnose, and prescribe — including controlled substances — under the state board of nursing alone.
Reduced practice	NPs need a collaborative agreement with a physician for at least one element of practice, such as prescribing.
Restricted practice	NPs require ongoing physician supervision, delegation, or team management to provide care.

In reduced and restricted states — for example California, Texas, and Georgia — an NP may still prescribe ketamine, but typically only within a documented collaborative or supervisory arrangement with a physician.

Why ketamine adds extra rules

Ketamine is a federally controlled Schedule III medication. To prescribe it, an NP needs:

• An active NP license in the state where the patient is located at the time of the visit.
• A federal DEA registration, and in some states a separate state controlled-substance registration.
• Prescriptive authority for controlled substances, which a few restricted states limit or condition on collaboration.

For telehealth specifically, federal flexibilities have at times allowed controlled substances to be prescribed after a video visit without a prior in-person exam. These rules have shifted, so reputable providers verify current DEA and state telemedicine requirements before prescribing.

At-home ketamine and provider models

Many telehealth ketamine programs use sublingual (under-the-tongue) ketamine prescribed for at-home use, often combined with virtual monitoring and therapy support. The clinician overseeing care may be a physician, an NP, or a physician assistant working within state law. Studies suggest ketamine may help some people with treatment-resistant depression and certain other conditions, but it is not a guaranteed cure and is not appropriate for everyone. A thorough screening for medical and psychiatric history, blood pressure concerns, and substance-use risk is an important safety step.

What this means when choosing a provider

For patients, the prescriber's title matters less than whether the provider is properly licensed in your state, transparent about clinical oversight, and following controlled-substance law. A qualified NP in a full-practice state can be every bit as appropriate as a physician for ketamine care.

When comparing options, look for clear answers to a few questions:

1. Is the clinician licensed in your state, and does that state allow them to prescribe ketamine for your situation?
2. How is dosing determined, monitored, and adjusted over time?
3. What screening, follow-up, and emergency support are included?
4. Are costs and any insurance options explained up front?

Frequently Asked Questions

Can a nurse practitioner prescribe ketamine without a doctor?

In full practice authority states, yes — qualified NPs can prescribe ketamine under their own license and DEA registration. In reduced or restricted states, an NP usually needs a collaborative or supervisory agreement with a physician to prescribe controlled substances.

Does the NP need to be licensed in my state for a telehealth ketamine visit?

Generally yes. The prescriber typically must be licensed in the state where you are physically located during the visit, hold DEA registration, and follow that state's telemedicine and controlled-substance rules.

Is ketamine prescribed by an NP as safe as one prescribed by a physician?

Safety depends on proper screening, dosing, and monitoring rather than the prescriber's title. A licensed NP practicing within state law can provide appropriate ketamine care. Always confirm the provider follows thorough screening and follow-up protocols.

Which states give nurse practitioners full prescribing authority?

Roughly half of U.S. states, including Arizona, Colorado, Oregon, Washington, Minnesota, and others, grant full practice authority. Because these laws change, verify your state's current status with its board of nursing.
