High certaintyADHD evidence
A guideline medicine for adults, with evidence it improves symptoms short term.
Start with the time you have

5 minutes
Write a few treatment goals and your questions about side effects.
15 minutes
Put your medicine list and medical history on one page for the prescribing appointment.
A plan
Discuss an individual treatment trial
- Bring goals and relevant health information.
- Ask the clinician about suitability, alternatives and follow-up.
- Review changes in functioning and adverse effects together.
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.
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.
