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.
- 13 trials
- 2944 people
- adults
- self rated
- about 12 weeks
- measured on core ADHD symptoms
EBI re-estimation: 13 trials, 2944 adults, short term self-ratings; NICE NG87 1.7.11 first-line medicine. See this row on the evidence map
The number, drawn
Why it matters
Methylphenidate acts on brain signalling involved in attention and behaviour. In EBI, adults rated their own symptoms 0.343 SMD better than on placebo, with high certainty, and the clinicians' ratings of improvement carry moderate certainty. The trials ran about 12 weeks or to their endpoint, so long term benefit is not established. NICE lists it with lisdexamfetamine as a first-line medicine for adults, yet more people left the trials because of adverse effects than on placebo, which is why the choice is a talk about benefits and harms.
How to do it
- Ask your ADHD clinician plainly whether methylphenidate suits you.
- Say which parts of work, study or home life you want treatment to improve.
- Go through your medical history, any other medicines, and what worries you about side effects.
- Before you leave, find out what to bring to follow-up and who to contact between appointments.
Whether it suits you, and the prescribing, are decisions for a qualified clinician. Bring your health history and every medicine you take, including ones bought without a prescription.
Putting it into practice
In real life
- Say whether your goal is getting essential work finished or keeping up with conversations.
- Ask how the review will look at unwanted effects as well as benefits.
Watch out for
- Common mistakeA bigger prescription is not the goal. Talk about how much it actually helps and how well you tolerate it.
- Common mistakeShort term symptom improvement does not guarantee every life difficulty will resolve; keep other support in the plan.
