ADHD
What differs, and how to raise medication timing with the prescriber.
The short version
- Do not change doses or timings at home. Medicines for Children: do not stop giving this medicine without talking to your doctor first.
- There is no national guidance for professionals on treating sleep problems in children with ADHD. If you feel you are improvising, so is everybody else.
- The ADHD brain takes longer to learn new routines, so allow months rather than weeks. A fortnight without progress is not failure.
- Sleep problems are a recognised side effect of ADHD medicines. Ask the prescriber to review the evening and monitor sleep with a diary.
- Without medication: late-afternoon exercise, daylight, screens off an hour or two before bed, a cool dark room, and no clocks in the bedroom.

ADHD
The honest context first, from University Hospital Southampton: "There is currently no national guidance for health professionals on treating sleep problems in children with ADHD." The word "sleep" appears three times in the whole NICE ADHD guideline. If you feel you are improvising, so is everybody else.
The honest UK figures come from the ALSPAC study (Scott and colleagues, 2013, 8,195 children): children with ADHD slept around 11 to 15 minutes less a night, and frequent waking, three or more times a night, rose to 6.4% at age 9 against under 1% of other children. Real, then, but not universal. What tends to differ: getting to sleep takes longer, the body clock may run late, sleep-disordered breathing, and a mind that will not stop.
Poor sleep can look like ADHD
Derbyshire NHS: "Poor sleep can mimic some symptoms of ADHD, especially concentration/inattention levels." Worth raising if your child is being assessed, and worth remembering if their ADHD seems worse during a bad patch of nights.
Medication and sleep
All of this is for the prescriber. Do not change doses or timings at home: "Do not stop giving this medicine without talking to your doctor first" (Medicines for Children).
- Sleep problems are a recognised side effect of methylphenidate, lisdexamfetamine and dexamfetamine (British National Formulary for Children).
- Timing may be adjustable. Medicines for Children notes this "can be helped by taking the last dose of methylphenidate at least 6 hours before bedtime". Ask the prescriber rather than trying it yourself.
- Rebound is recognised, and the answer is counter-intuitive. The BNF for Children: "if effect wears off in evening (with rebound hyperactivity) a dose at bedtime may be appropriate (establish need with trial bedtime dose)". Only a prescriber can set that up.
- Ask for the evening to be reviewed. NICE requires an annual review of "how well the current treatment is working throughout the day", and says to monitor sleep with a diary "and adjust medication accordingly".
Without medication: gentle late-afternoon exercise, daylight in the day, screens off an hour or two before bed, a cool dark room. Two smaller ones: take clocks out of the bedroom, because watching the time causes anxiety, and "if the light was on when your child went to bed, leave it on".
The realism line
From Derbyshire NHS: "Remember that the ADHD brain takes longer to learn new routines so give it time (months rather than weeks)." A new bedtime that has not worked in a fortnight is not a failure. That is the expected timescale.
