Disclaimer: This article is for informational purposes only and does not constitute medical advice. ADHD medications are prescription-only in most countries and should only be taken under the supervision of a licensed healthcare provider. Medication needs vary significantly between individuals. Do not start, stop, or change medications without consulting your doctor.
I was diagnosed with ADHD at 31. My psychiatrist walked me through the medication options in about 15 minutes — which felt insufficient for decisions that significantly affect how your brain functions daily. I spent the following months reading prescribing guidelines, clinical trials, and patient experience research. This guide is what I wish I’d had going in.
I want to be clear: medication works differently for every person. What I’ve taken, what worked for me, and what the studies show are all useful data points — but your prescriber needs to know your full medical history, current medications, and cardiovascular status before recommending anything.
The Two Main Categories
ADHD medications fall into two broad categories: stimulants (first-line treatment) and non-stimulants (second-line or adjunct treatment). About 70-80% of people with ADHD respond positively to stimulant treatment [1].
Stimulants: Methylphenidate-Based
Ritalin (methylphenidate IR): Immediate-release, works within 30-60 minutes, duration 3-5 hours. Oldest and most extensively studied ADHD medication. Often used as a starting point for dose titration.
Concerta (methylphenidate ER): Extended-release via OROS delivery system, 10-12 hours duration. Once-daily dosing is a significant quality-of-life improvement.
Vyvanse analogue (lisdexamfetamine — not methylphenidate, see below).
Focalin (dexmethylphenidate): The active d-isomer of methylphenidate. Some patients report cleaner effect with fewer side effects than racemic methylphenidate.
Stimulants: Amphetamine-Based
Adderall (mixed amphetamine salts): 75% d-amphetamine, 25% l-amphetamine. IR version lasts 4-6 hours; XR version 8-12 hours. Generally considered slightly stronger than equivalent methylphenidate doses.
Vyvanse (lisdexamfetamine): A prodrug — converted to active d-amphetamine in the body. Smooth onset, 10-14 hour duration, lower abuse potential than Adderall due to slow conversion. FDA-approved for both ADHD and binge eating disorder [2]. Most expensive in the class but often preferred for its consistent effect curve.
Dexedrine (dextroamphetamine): Pure d-amphetamine. Less commonly prescribed but effective.
Non-Stimulants
Strattera (atomoxetine): A selective norepinephrine reuptake inhibitor. Not a controlled substance — important for patients with substance use history. Takes 4-8 weeks for full effect. Less effective on average than stimulants but meaningfully effective for many people. Once-daily dosing.
Wellbutrin (bupropion): Primarily an antidepressant but off-label used for ADHD, particularly when comorbid depression is present. Inhibits reuptake of both norepinephrine and dopamine.
Intuniv / Kapvay (guanfacine / clonidine ER): Alpha-2 agonists originally developed for blood pressure. Reduce hyperactivity and impulsivity, improve emotional regulation. Often used as adjuncts to stimulants or for children who can’t tolerate stimulants. Less effect on inattention than stimulants.
Side Effects to Know
Common stimulant side effects: appetite suppression, elevated heart rate and blood pressure, sleep disruption (especially with afternoon doses), dry mouth. Most diminish after 2-4 weeks of consistent use [3].
Less common but important: Stimulants can worsen anxiety in people with anxiety disorders. Cardiovascular screening is standard before prescribing — stimulants are generally contraindicated in people with structural heart defects or certain arrhythmias.
Cost Reality
Generic methylphenidate and generic Adderall are typically $20-50/month with GoodRx at major pharmacies. Vyvanse, still brand-only through 2024 (generic lisdexamfetamine became available in late 2023), runs $200-350/month without insurance. Strattera generics are available and significantly cheaper than brand.
