Stimulants vs non-stimulants for ADHD

Two broad categories
ADHD medications fall into two groups, and a prescriber chooses based on your child's specific profile, other health conditions, and how they respond over time — not a one-size-fits-all rule.
Stimulants
Methylphenidate (e.g. Ritalin, Concerta) and amfetamine-based medicines (e.g. Elvanse) are the most commonly prescribed ADHD medications. Despite the name, they work by increasing certain brain chemicals (dopamine and noradrenaline) that improve focus and impulse control — for most people with ADHD, the effect is calming and clarifying rather than stimulating.
They tend to act quickly (within an hour) and their effects wear off within hours to a day, depending on the formulation (immediate-release vs long-acting).
Non-stimulants
Atomoxetine and guanfacine work differently and are typically considered when stimulants aren't suitable or effective — for example, if there's a history of tics, significant anxiety, or cardiac considerations, or if stimulants caused unacceptable side effects.
Non-stimulants generally take longer to show full effect — often several weeks — and are taken daily rather than only on days needed.
How a choice gets made
A prescriber will typically consider:
- Severity and pattern of symptoms (e.g. all day vs mainly at school)
- Co-occurring conditions (tics, anxiety, sleep difficulties, heart conditions)
- Family preference around daily vs as-needed dosing
- Response and side effects during a trial period — medication choice is often adjusted after the first few weeks based on real-world feedback
What to expect when starting
- A "start low, go slow" approach is standard — doses are usually increased gradually
- Regular review appointments (especially in the first few months) to check growth, heart rate, blood pressure, appetite, and effectiveness
- It's normal to try more than one medication or dose before finding the right fit
When to talk to your clinician
Always discuss with your prescriber rather than adjusting independently:
- Loss of appetite affecting growth
- Sleep difficulties that didn't exist before starting
- Any new tics, mood changes, or chest symptoms
- A sense that the medication "wears off" badly before the next dose
