Can a Psychiatric Nurse Practitioner Prescribe Medication?
Reviewed by Josie Desmarais, PMHNP-BC · Board-Certified Psychiatric-Mental Health Nurse Practitioner · Last updated August 2026
Yes. Psychiatric nurse practitioners (PMHNPs) can prescribe medication in Florida — including antidepressants, mood stabilizers, antipsychotics, and Schedule II controlled substances like Adderall. Florida grants PMHNPs full prescribing authority, meaning no physician co-signature or supervisory oversight is required.
Short answer: Psychiatric medication works best with ongoing management. A provider can review your medications, adjust doses, and monitor for side effects.
PMHNPs handle full medication management, from first prescription to long-term adjustments.
What Florida Law Says About PMHNP Prescribing
Florida is a full-practice authority state for nurse practitioners. Under Florida Statute § 464.012, a certified nurse practitioner — including a PMHNP-BC — may prescribe, dispense, and administer medications within their specialty area without a physician collaborative practice agreement. For more on this, see our guide to how an NP can diagnose ADHD and prescribe Adderall.
This matters because prescribing authority for nurse practitioners varies by state. In some states, NPs must practice under physician supervision or maintain co-signing arrangements. Florida has no such restriction for certified NPs. A PMHNP here operates with the same independent prescribing authority as a psychiatrist — within the psychiatric scope of practice.
Florida extended full NP practice authority to address the mental health provider shortage, particularly in underserved areas. Patients in West Palm Beach and across the state can access psychiatric medication management from a PMHNP without structural barriers. We cover online prescribing by a psychiatric NP in a separate article.
What Medications a PMHNP Can Prescribe
The full range of psychiatric pharmacology is within scope. This includes:

Antidepressants
SSRIs (sertraline, escitalopram, fluoxetine), SNRIs (venlafaxine, duloxetine), atypical antidepressants (bupropion, mirtazapine), TCAs, and MAOIs.
Mood Stabilizers
Lithium, valproate (Depakote), lamotrigine (Lamictal), and atypical antipsychotics used for mood stabilization.
Antipsychotics
First- and second-generation antipsychotics for schizophrenia, schizoaffective disorder, bipolar disorder with psychotic features, and treatment augmentation.
Anti-anxiety Medications
Buspirone, hydroxyzine, SSRIs and SNRIs (first-line for generalized anxiety), and benzodiazepines when clinically indicated.
Sleep Medications
Non-benzodiazepine sleep aids — trazodone, low-dose mirtazapine, z-drugs — within psychiatric practice.
Schedule II ADHD Medications
This is the category patients most often ask about. Florida PMHNPs can prescribe Schedule II controlled substances, including:
- Amphetamine salts (Adderall, Adderall XR)
- Lisdexamfetamine (Vyvanse)
- Methylphenidate (Ritalin, Methylin)
- Dexmethylphenidate (Focalin, Focalin XR)
- Long-acting methylphenidate formulations (Concerta, Metadate ER)
Schedule II prescriptions carry the highest level of prescribing accountability — DEA registration, no refills, electronic or secure paper only. A Florida PMHNP with DEA registration handles all of this independently.
How PMHNP Prescribing Compares to Psychiatrists and Primary Care
Versus psychiatrists (MD/DO): Prescribing scope is identical in Florida. A psychiatrist does not have access to any medication category unavailable to a PMHNP. Training pathways differ, but the licensing outcome for outpatient prescription authority is the same. If that applies to you, read more about whether nurse practitioners can prescribe antidepressants.
Versus primary care physicians (PCPs): PCPs can technically prescribe psychiatric medications, but most prefer not to manage complex psychiatric conditions long-term. Antidepressants are frequently started in primary care, but patients with ADHD, bipolar disorder, treatment-resistant depression, or psychosis are typically referred to a psychiatric specialist. A PMHNP is that psychiatric specialist.
Versus therapists (LCSW, LPC, psychologists): Therapists cannot prescribe medication in Florida. If you are working with a therapist and need a medication evaluation, that requires a separate appointment with a PMHNP or psychiatrist. Our team also explains choosing between a nurse practitioner and a psychiatrist in detail.

Frequently Asked Questions
Q: Can a psychiatric nurse practitioner prescribe controlled substances in Florida?
A: Yes. Florida PMHNPs with DEA registration can prescribe Schedule II through Schedule V controlled substances, including stimulants for ADHD (Adderall, Vyvanse, Ritalin) and benzodiazepines when clinically appropriate.
Q: Does a PMHNP need a doctor to approve prescriptions?
A: Not in Florida. Florida is a full-practice authority state. A board-certified NP prescribes independently — no physician co-signature or supervision agreement is required. Learn more about what a psychiatric nurse practitioner does here.
Q: Can a nurse practitioner prescribe antidepressants?
A: Yes. Antidepressants are squarely within PMHNP prescribing scope — SSRIs, SNRIs, bupropion, mirtazapine, and other classes.
Q: Can a psychiatric nurse practitioner adjust or change my existing psychiatric medication?
A: Yes. Ongoing medication management — dose adjustments, medication switches, augmentation strategies, deprescribing — is a core function of PMHNP practice.
Q: Is there any medication a PMHNP cannot prescribe that a psychiatrist can?
A: In Florida, no meaningful prescribing difference exists between a psychiatrist and a PMHNP for outpatient psychiatric practice. Both operate under the same regulatory framework and DEA schedule system. You may also want to understand whether an NP can perform a psychiatric evaluation.
