Non-Stimulant ADHD Medications for ADHD

Effective ADHD treatment without controlled substances — for patients who prefer to avoid stimulants

Non-Stimulant Atomoxetine / Bupropion / Guanfacine / Clonidine

Overview

Non-stimulant medications are an important option for patients who cannot tolerate stimulants, have a history of substance use disorder, have cardiovascular contraindications, or simply prefer to avoid Schedule II controlled substances. While non-stimulants generally have slower onset and may be less dramatically effective than stimulants, they provide meaningful symptom relief for many patients.

How It Works

Each non-stimulant works differently: Atomoxetine (Strattera) selectively inhibits norepinephrine reuptake. Bupropion (Wellbutrin) inhibits dopamine and norepinephrine reuptake. Guanfacine (Intuniv) and clonidine (Kapvay) are alpha-2 adrenergic agonists that strengthen prefrontal cortex function through a distinct mechanism.

Available Formulations

Atomoxetine (Strattera) — once or twice daily, generic available
Bupropion XL (Wellbutrin) — once daily, also treats depression and helps with smoking cessation
Guanfacine ER (Intuniv) — once daily, also reduces blood pressure
Clonidine ER (Kapvay) — twice daily, useful for ADHD with significant hyperactivity
Viloxazine ER (Qelbree) — newest non-stimulant, similar to atomoxetine

Side Effects & Monitoring

⚠ Atomoxetine: nausea (take with food), decreased appetite, mood changes, rare liver toxicity (monitor)
⚠ Bupropion: insomnia, decreased appetite, headache, seizure risk in eating disorders
⚠ Guanfacine/Clonidine: sedation (particularly initially), low blood pressure, rebound hypertension if stopped abruptly
⚠ All non-stimulants: 4–6 week onset to full therapeutic effect (unlike stimulants, which work immediately)

Monitoring: Atomoxetine: liver function tests if symptoms develop. Guanfacine/Clonidine: blood pressure monitoring, particularly when adjusting doses. Bupropion: mood monitoring, particularly in patients with bipolar disorder (can trigger mania). All: symptom response assessment at 4–6 weeks after reaching target dose.

Prescription Management With Direct Access

ADHD medication often requires adjustment in the first months of treatment — dose titration, formulation changes, timing adjustments. With Dr. Agresti's concierge model, you can text him directly when something isn't working. No 6-week wait for the next appointment to report that your medication stops working by 2 PM.
