Can a Nurse Practitioner Diagnose ADHD and Prescribe Adderall?
Reviewed by Josie Desmarais, PMHNP-BC · Board-Certified Psychiatric-Mental Health Nurse Practitioner · Last updated August 2026
Yes on both. In Florida, a psychiatric nurse practitioner (PMHNP-BC) can diagnose ADHD and prescribe Schedule II stimulants including Adderall and Vyvanse. No legal or regulatory requirement exists to see a psychiatrist or physician for ADHD evaluation or treatment in Florida — a PMHNP with DEA registration handles this independently.
Short answer: ADHD is diagnosable and treatable in adults. A psychiatric evaluation can confirm the diagnosis and guide medication or behavioral treatment that fits your life.
A structured ADHD treatment evaluation determines whether a stimulant like Adderall is appropriate.
Can a Nurse Practitioner Diagnose ADHD in Florida?
Yes. ADHD diagnosis falls squarely within the PMHNP scope of practice. A psychiatric nurse practitioner is trained to conduct the clinical interviews, behavioral assessments, and rating scales used to evaluate ADHD — and is licensed to assign the DSM-5-TR diagnosis. For more on this, see our guide to whether a psychiatric NP can prescribe medication.
Adults seeking an ADHD evaluation should see a psychiatric specialist rather than a primary care provider. PCPs can screen for ADHD and sometimes initiate treatment, but a thorough evaluation that includes differential diagnosis — ruling out anxiety, mood disorders, sleep disorders, and other conditions that mimic ADHD — requires a psychiatric clinician.
At Trust Psychiatry & Wellness, the ADHD evaluation includes:
- A structured clinical interview covering symptom history, onset, and functional impairment
- Validated rating scales (Adult ADHD Self-Report Scale and Conners’ Adult ADHD Rating Scales)
- A TOVA (Test of Variables of Attention) — an objective, computer-based performance test that measures attention and impulse control, available at the West Palm Beach office
- Review of prior records and collateral information where relevant
- Differential diagnosis to rule out co-occurring conditions
The TOVA is a meaningful differentiator. Most outpatient psychiatric practices rely exclusively on self-report and interview data. Objective performance testing adds a data point that strengthens diagnostic confidence and supports the clinical record. We cover online prescribing by a psychiatric NP in a separate article.
What Stimulants a PMHNP Can Prescribe in Florida
Florida grants PMHNPs full prescribing authority under its full-practice statute — no physician supervision or co-signing required. For ADHD specifically, this includes:
Schedule II stimulants:
- Amphetamine salts — Adderall (IR), Adderall XR
- Lisdexamfetamine — Vyvanse
- Dextroamphetamine — Dexedrine
- Methylphenidate — Ritalin (IR and SR)
- Dexmethylphenidate — Focalin, Focalin XR
- Extended-release methylphenidate — Concerta, Metadate CD, Quillivant XR, Jornay PM
Non-stimulant ADHD medications (Schedule IV or unscheduled):
- Atomoxetine (Strattera) — norepinephrine reuptake inhibitor, non-controlled
- Viloxazine (Qelbree) — newer non-stimulant, unscheduled
- Guanfacine ER (Intuniv) — alpha-2 agonist, used as adjunct or standalone
- Clonidine ER (Kapvay) — alpha-2 agonist, similar profile
Schedule II prescriptions require a DEA registration, cannot be refilled (new prescription required each fill), and must be issued electronically or on secure paper. A Florida PMHNP with DEA registration manages all of this independently. If that applies to you, read more about whether nurse practitioners can prescribe antidepressants.
Telehealth ADHD Diagnosis in Florida
Adults can receive an ADHD evaluation and ongoing medication management via telehealth in Florida. Trust Psychiatry offers telehealth psychiatric services statewide — patients anywhere in Florida can see Josie Desmarais, PMHNP-BC without coming to the West Palm Beach office.
One practical note: the TOVA test is administered in-office. For patients who want objective performance testing as part of their evaluation, an in-person visit to the West Palm Beach location is required for that component. The rest of the evaluation — clinical interview, rating scales, and follow-up appointments — can be conducted via telehealth.
For patients who already have a prior diagnosis and are seeking medication management or a second opinion, telehealth works from the start.
How This Compares to Seeing a Psychiatrist for ADHD
The process is functionally the same. A psychiatrist (MD or DO) and a PMHNP-BC use the same diagnostic tools, apply the same DSM-5-TR criteria, and prescribe from the same medication formulary. In Florida, no prescribing limitation makes a psychiatrist more capable of treating ADHD than a PMHNP. Our team also explains whether Adderall is addictive with ADHD in detail.
The practical advantage of seeing a PMHNP: availability. Psychiatrists specializing in adult ADHD have long wait times. PMHNPs fill that access gap without clinical compromise.
Frequently Asked Questions
Q: Can a nurse practitioner diagnose ADHD in adults?
A: Yes. A PMHNP-BC is trained and licensed to diagnose ADHD using clinical interviews, validated rating scales, and standardized assessment tools. This is within their core scope of practice in Florida. Learn more about whether ADHD meds show up on drug tests here.
Q: Can a psychiatric nurse practitioner prescribe Adderall?
A: Yes. Adderall is a Schedule II controlled substance. Florida PMHNPs with DEA registration prescribe Schedule II medications independently, without a physician co-signature.

A: Yes. Vyvanse (lisdexamfetamine) is a Schedule II stimulant. A Florida PMHNP can prescribe it on the same basis as Adderall.
Q: Can I get an ADHD diagnosis over telehealth in Florida?
A: Yes, for the clinical interview and rating-scale components. Trust Psychiatry also offers the TOVA objective performance test in-office at the West Palm Beach location for patients who want that data point included in their evaluation. You may also want to understand choosing between a nurse practitioner and a psychiatrist.
