Atomoxetine

NRI

Sedating: No Driving: Caution QT risk: Moderate Akathisia: Moderate Metabolic: Low Prolactin: Low t½: 5 h Tmax: 1 h

The non-stimulant ADHD med. Atomoxetine works by blocking noradrenaline reuptake, and is often given when stimulants (methylphenidate, dexamfetamine) don’t work or aren’t tolerated. The upside: no abuse potential, no sudden crash. The downside: it’s slow, can worsen anxiety, and can feel underwhelming compared to the rocket fuel of stimulants. Still, for some people, it’s the steady background focus they need.
