Yes, Certified Registered Nurse Practitioners (CRNPs) can prescribe medications, including controlled substances, in all 50 states. The exact scope of what they can prescribe and how independently they can do it depends on the state where they practice. Some states give CRNPs full prescribing autonomy comparable to physicians, while others require a collaborative agreement with a doctor.
What CRNPs Can Prescribe
CRNPs can prescribe the full range of medications you’d expect from a primary care or specialty provider: antibiotics, blood pressure drugs, antidepressants, diabetes medications, inhalers, birth control, and more. They can also prescribe controlled substances (Schedule II through V), which includes medications like opioid painkillers, stimulants for ADHD, anti-anxiety drugs, and sleep aids.
There are a few notable exceptions. In Georgia, Oklahoma, South Carolina, and West Virginia, CRNPs cannot prescribe Schedule II medications. Schedule II is the most tightly regulated category and includes drugs like oxycodone, amphetamine-based ADHD medications, and fentanyl. In those states, you’d need a physician to write that particular prescription. In every other state, CRNPs have the legal authority to prescribe across all controlled substance schedules.
Beyond medications, CRNPs can also order durable medical equipment like CPAP machines, wheelchairs, and glucose monitors, though this requires prescriptive authority in the same way writing a prescription does.
Full Practice vs. Collaborative Practice States
The biggest variable in CRNP prescribing isn’t what they can prescribe but how much oversight is required. States fall into roughly two categories.
In full practice states, CRNPs operate independently. They evaluate patients, diagnose conditions, and prescribe treatments without needing a physician to co-sign or supervise. This gives patients essentially the same prescribing experience they’d have with a doctor.
In restricted or collaborative practice states, CRNPs must have a formal agreement with a collaborating physician before they can prescribe. New Jersey, for example, requires a joint protocol with a licensed physician prior to prescribing any medication or device. The specifics of these agreements vary. Some require the physician to periodically review a percentage of charts, while others are more of a formality where the physician is available for consultation but doesn’t approve each prescription individually. From your perspective as a patient, the process typically feels the same either way: the CRNP evaluates you and writes the prescription during your visit.
DEA Registration for Controlled Substances
To prescribe any controlled substance, a CRNP must hold their own DEA registration number. The DEA classifies nurse practitioners as “mid-level practitioners,” a category that also includes nurse midwives, nurse anesthetists, clinical nurse specialists, and physician assistants. This registration is separate from their state nursing license and specifically authorizes them to prescribe controlled drugs within the bounds their state allows.
If you’re filling a controlled substance prescription from a CRNP, the pharmacy verifies this DEA number just as it would for a physician’s prescription. There’s no difference in how the prescription is processed on the pharmacy end.
Prescription Monitoring Requirements
Before prescribing controlled substances, many CRNPs are required to check a state-run Prescription Drug Monitoring Program (PDMP). These databases track controlled substance prescriptions filled by each patient, helping providers identify potential misuse or dangerous combinations. Some states mandate a PDMP check before every controlled substance prescription, while others leave it to the provider’s judgment. If you’re prescribed a controlled substance by a CRNP, they’ve likely already reviewed your prescription history through this system.
Telehealth Prescribing
CRNPs can prescribe medications, including controlled substances, through telehealth visits. During the COVID-19 pandemic, federal rules were relaxed to allow controlled substance prescriptions via video or phone without requiring an in-person evaluation first. The DEA and the Department of Health and Human Services have extended these flexibilities through December 31, 2026. This means a DEA-registered CRNP can prescribe Schedule II through V controlled substances during a telehealth appointment, provided other conditions are met. After that date, new rules may require an initial in-person visit before controlled substances can be prescribed remotely.
Training Behind Prescriptive Authority
CRNPs don’t prescribe medications casually. Their graduate-level education includes dedicated pharmacology training. In New Jersey, for example, certification requires at least a three-credit graduate pharmacology course or 45 integrated pharmacology hours within a master’s nursing program. If that coursework was completed more than five years before applying for prescriptive authority, the CRNP must either retake the course or complete 30 hours of continuing education covering how drugs work in the body, how they interact, and how they’re used to prevent illness and maintain health.
This pharmacology training is specific to their practice specialty. A family practice CRNP studies medications relevant to primary care, while a psychiatric CRNP focuses on psychotropic medications. Combined with hundreds of clinical hours during their graduate program and ongoing continuing education requirements, CRNPs build a working knowledge of medications that’s tailored to the patients they actually see.
The APRN Compact and Multistate Practice
If you see a CRNP through telehealth or are moving between states, licensing matters. Currently, CRNPs must hold a license in each state where they practice. An emerging solution is the APRN Compact, which would allow nurse practitioners to hold one license and practice across member states. As of early 2025, only four states (North Dakota, Delaware, Utah, and South Dakota) have enacted the compact. It won’t take effect until at least seven states join, so for now, your CRNP needs to be licensed in the state where you’re located at the time of your appointment.
