How sure the science is

High certainty, ADHD evidence

Enough good trials that more research is unlikely to change this number much. Measured in people with ADHD.

  • 7 trials
  • 1734 people
  • adults
  • self rated
  • about 12 weeks
  • measured on core ADHD symptoms

EBI re-estimation: 7 trials, 1734 adults; high certainty applies specifically to short term self-ratings; NICE NG87 1.7.15. See this row on the evidence map

The number, drawn

0.370.27 to 0.47self-rated core ADHD symptom improvement in adultsvs placebo; 7 trials, 1734 people. BMJ / Gosling et al., 20250.2 is a small effect, 0.5 medium, 0.8 large. The bar is the 95% confidence interval.

Why it matters

Atomoxetine is a nonstimulant medicine that affects noradrenaline signalling. EBI found a 0.368 SMD improvement in adults' self-rated symptoms versus placebo, with high certainty, but clinician-rated evidence was very low certainty. These findings concern about 12 weeks or trial endpoint, and do not establish long term benefit. NICE recommends it for adults who cannot tolerate, or have not been helped by, lisdexamfetamine and methylphenidate; more participants withdrew because of adverse effects than with placebo.

How to do it

  1. Ask whether a nonstimulant makes sense given your previous treatment and medical history.
  2. Bring a short account of what stimulants did for you, the side effects, or why they may not suit you.
  3. Ask how long the clinician expects it to take before you can judge whether it helps.
  4. Talk through possible unwanted effects and set up a review plan.

A clinician should decide whether it suits you, check interactions and plan monitoring. This adult estimate cannot be assumed to apply to children or to every outcome.

Putting it into practice

In real life

  • Ask: 'What would count as enough benefit, and when would we review it?'
  • Bring up your concerns about previous medicines, including effects that felt awkward to mention.

Watch out for

  • Common mistakeNonstimulant does not mean free of side effects. Ask how you'll be monitored.
  • Common mistakeSelf-ratings and clinician ratings got different certainty ratings. Talk about the benefits that matter in your own life.
