Melatonin in the UK
Prescription-only here, and what that means in practice. No doses.
The short version
- Melatonin is a prescription-only medicine in the UK. Do not buy it online or bring it back from abroad.
- Those supplements are not quality-assured for UK supply, and they bypass the specialist assessment that finds the treatable cause.
- Behavioural work comes first. The licence covers use where sleep hygiene measures have been insufficient, and a baseline sleep diary is expected before any trial.
- Parents tend to report melatonin helps their child get to sleep, but not to stay asleep. It helps less if bedtime is not already calm.
- Reviews, planned breaks and stopping are the prescriber's job. Do not run your own drug holiday, and ask when the review is due.

Melatonin in the UK
We give no doses anywhere on this site. Doses are the prescriber's decision. Melatonin is a prescription-only medicine in the UK. The NHS says it "is available on prescription only" and "can also sometimes be prescribed by specialists to help with longer-term sleep problems in some children and adults".
Do not buy it online or bring it back from abroad
Melatonin is sold over the counter in some countries. NHS-funded prescribing guidance is explicit that "these supplements are not authorised for sale in the UK, where melatonin is a prescription-only medicine". They are not quality-assured for UK supply, and they bypass the specialist assessment that finds the treatable cause.
The UK licence covers insomnia in children and young people with autism or a neurogenetic disorder, and in a narrower age band with ADHD, and in both cases the licensed indication itself includes the phrase "where sleep hygiene measures have been insufficient". That is the strongest possible basis for saying behavioural work comes first. Everything else is off-label or unlicensed. NICE guidance on autism says not to use medication for sleep unless problems persist despite the sleep plan, and then only after consultation with a specialist and alongside non-medication approaches. Scottish guidance adds that "an adequate baseline sleep diary should be obtained before any trial of melatonin".
Cerebra is realistic about what to expect: melatonin "won't be very effective for a child who is drinking a coke and playing video games at midnight, but it may help a child who is able to be calmed in a dimly lit bedroom", and parents "tend to report that melatonin helps their child to get to sleep, but not to stay asleep". Reviews, planned breaks and stopping are the prescriber's job: do not run your own drug holiday, and ask when the review is due. There is a plain-English leaflet from Medicines for Children.
