Psychiatrists, primary care physicians, nurse practitioners, and physician assistants can all prescribe psychotropic medications in the United States. In fact, more than 60% of psychotropic prescriptions are written by providers other than psychiatrists, with primary care accounting for the largest share. The specific rules governing who can prescribe, and how independently, vary by state and by provider type.
Psychiatrists and Other Physicians
Any licensed physician with an M.D. or D.O. degree can legally prescribe psychotropic medications, regardless of their specialty. This includes psychiatrists, family medicine doctors, internists, pediatricians, neurologists, and OB-GYNs. Psychiatrists complete additional years of residency training focused specifically on mental health conditions and psychopharmacology, which makes them the most specialized prescribers. But there are far fewer psychiatrists than there are people who need psychiatric medication, which is why most prescribing happens elsewhere in the healthcare system.
Primary Care Writes Most Prescriptions
Primary care providers prescribe the majority of psychiatric medications in the U.S. Among Medicare beneficiaries with serious mental illness, primary care physicians prescribed 64% of all psychiatric medications, while behavioral health specialists prescribed just 19.1%. The gap is even wider in rural areas, where primary care accounts for over 70% of prescriptions across nearly every psychiatric drug class. Even antipsychotics, which are the medication class most likely to come from a psychiatrist, were still prescribed by primary care doctors 60% of the time in rural settings and 45% of the time in urban areas.
This pattern holds across all ages. A large analysis of over 58,000 psychotropic prescriptions found that general practitioners, nurse practitioners, and physician assistants collectively wrote a larger share than psychiatrists and psychologists combined. For many people, especially those without easy access to a psychiatrist, their family doctor or internist is the provider managing their antidepressant, anti-anxiety medication, or sleep aid.
Nurse Practitioners
Nurse practitioners, particularly those with a psychiatric-mental health specialization (known as PMHNPs), are among the fastest-growing groups of psychotropic prescribers. Their level of independence depends entirely on the state where they practice. Some states grant nurse practitioners full independent practice and prescriptive authority from the start, meaning no physician oversight is required. Others require a collaborative agreement with a physician, at least for an initial transition period. In Connecticut, for example, nurse practitioners must collaborate with a physician for the first three years after licensure, then may practice independently.
The National Council of State Legislatures identifies five tiers of authority across states, ranging from full independence to a mandatory ongoing physician relationship for both practice and prescribing. If you’re seeing a nurse practitioner for psychiatric care, their ability to prescribe controlled substances like stimulants or benzodiazepines also depends on whether they’ve applied for and received the appropriate state and federal authorization. In states like Alaska, nurse practitioners can independently prescribe controlled substances in Schedules II through V after obtaining that authority.
Physician Assistants
Physician assistants can prescribe psychotropic medications, but they work under physician supervision in most states. The supervising physician delegates prescriptive authority, typically through a written agreement that specifies what the PA is authorized to prescribe. In Florida, for instance, a supervising physician may delegate authority to prescribe any medication used in their practice, and the physician remains legally responsible for the PA’s prescribing decisions. A single physician generally cannot supervise more than a set number of PAs at one time (10 in Florida).
In practical terms, if you see a PA at a psychiatric practice or primary care office, they can prescribe antidepressants, mood stabilizers, antipsychotics, and in many cases controlled substances, as long as their supervising physician has authorized it. Some states have been expanding PA autonomy in recent years, reducing or eliminating certain supervision requirements.
Psychologists With Prescriptive Authority
Psychologists cannot prescribe in most of the country, but a growing number of states have changed that. As of October 2024, seven states allow specially trained psychologists to prescribe psychotropic medications: New Mexico (since 2002), Louisiana (2004), Illinois (2014), Iowa (2016), Idaho (2017), Colorado (2023), and Utah (2024). Psychologists in Guam, the military and Department of Defense, the Indian Health Service, and the Public Health Service also have prescriptive authority.
These psychologists must complete additional postdoctoral training in psychopharmacology beyond their doctoral degree. They are not simply granted prescribing rights with their psychology license. In states without this authority, psychologists provide therapy and psychological testing but refer to other providers when medication is needed.
Clinical Pharmacists in Specific Settings
Clinical pharmacists don’t prescribe psychotropic medications in typical outpatient settings, but within the Department of Veterans Affairs, clinical pharmacist practitioners have had prescriptive authority under a defined scope of practice for more than four decades. In VA psychiatric settings, these pharmacists perform patient assessments, order lab tests, and adjust medication therapy. They manage conditions including major depression, PTSD, psychotic disorders, bipolar disorder, and substance use disorders. Their authority does not extend to controlled substances that require a DEA registration number, but they can manage a wide range of psychiatric medications within the VA system.
Controlled Substance Requirements
Many psychotropic medications, including stimulants for ADHD (Schedule II) and benzodiazepines for anxiety (Schedule IV), are federally classified as controlled substances. Any provider prescribing these drugs must be registered with the Drug Enforcement Administration and include their DEA number on every prescription. The prescription must be dated and signed on the day it’s issued, include the patient’s full name and address, and meet specific formatting rules. Schedule II prescriptions must be written or electronic, with limited exceptions for emergencies when a verbal order may be accepted.
These requirements apply equally to psychiatrists, primary care doctors, nurse practitioners, and physician assistants. The type of license doesn’t change the federal rules; it only determines whether the provider’s state allows them to prescribe controlled substances in the first place.
Telehealth Prescribing
Federal law historically required an in-person visit before a provider could prescribe controlled substances. During the COVID-19 pandemic, that requirement was suspended, and those flexibilities have been extended multiple times since. As of January 2026, HHS and the DEA extended telemedicine prescribing rules through December 31, 2026, allowing patients to receive controlled substance prescriptions without a prior in-person visit while permanent regulations are finalized. This is particularly relevant for psychiatric medications like stimulants and benzodiazepines that many patients now receive through telehealth platforms. All prescriptions must still be issued for legitimate medical purposes by licensed practitioners who comply with federal and state law.
Special Considerations for Children
Any provider with prescriptive authority can technically prescribe psychotropic medications to children, but clinical guidelines recommend additional caution. California’s guidelines for children in foster care, for example, recommend that psychotropic medications be prescribed only by specialists in child and adolescent psychiatry, neurodevelopmental pediatrics, developmental-behavioral pediatrics, pediatric neurology, or primary care physicians with specialized training in high-risk children. California law also requires judicial approval before administering psychotropic medications to children and youth in foster care.
Even outside the foster care system, pediatric psychotropic prescribing generally involves more oversight. Many primary care providers will start a child on a common antidepressant or ADHD medication but refer to a child psychiatrist for more complex cases or when multiple medications are involved.
