Melatonin for Children – What Parents Should Know

In Sweden, melatonin for children should be managed through a healthcare provider – it is a doctor or paediatrician who assesses whether it is appropriate, at what dose and for how long. Do not give a child melatonin on your own without first talking to your child health centre (BVC) or health centre. Before considering melatonin, the recommendation is always to work first with sleep routines and the sleep environment, which have the strongest support for children's sleep.

Why melatonin for children is a healthcare matter

Melatonin is a hormone that the body produces itself and which regulates the circadian rhythm. In adults there is an EFSA-approved claim that melatonin contributes to shortening the time it takes to fall asleep. For children the situation is different: children's sleep, circadian rhythm and the underlying causes of sleep difficulties differ from those of adults, and the use of melatonin in children in Sweden is mainly linked to a medical assessment – often in connection with specific conditions that are being investigated within healthcare.

The starting point is therefore simple and clear: dosage, suitability and treatment length for children are a medical assessment, not something you work out by trial and error at home.

Always start with the sleep routines first

Both healthcare guidance and the Swedish Medical Products Agency are clear: non-pharmacological measures – that is, habits, routines and the sleep environment – are the first choice for children's sleep problems, and have the strongest support. Before melatonin is even on the table, the basics should be in place over a continuous period, since new routines often need a couple of weeks to settle.

Routines and environment that are supported

• Regular times – the same bedtime and wake-up time, even at weekends, so that the circadian rhythm stabilises.
• Calm wind-down – a predictable routine in the last hour: dimmed light and calm activities. For younger children this might be a bath, pyjamas and story time.
• Screen-free bedtime – preferably a screen-free hour before bed, and keep phones and tablets out of the bedroom. Light in the evening can slow the body's own melatonin production.
• Sleep environment – a dark, cool and quiet room. A night light can be used if needed.
• Daylight and movement – time outdoors and physical activity during the day strengthen the circadian rhythm, but avoid intense activity right before bed.
• Avoid overtiredness – a child who becomes too tired can find it harder to fall asleep. Watch for early signs of tiredness.

In practice, consistent routines resolve a large part of everyday difficulties falling asleep in children, and they are always the first choice – even if healthcare later judges that something more is needed.

What healthcare does – investigation, assessment and follow-up

If the sleep problems are persistent, worsen or clearly affect the child's wellbeing and daily life, raise it with your child health centre (BVC) or health centre. Healthcare usually starts by mapping the sleep and looking for underlying causes rather than going straight for a medicine.

Here is what the route through healthcare might look like:

• Mapping – a sleep diary, habits and environment are reviewed. Sometimes there is a cause such as worry, pain, breathing problems or stress that should be addressed first.
• Non-pharmacological measures – advice on sleep routines, and if needed more structured support. This is the first choice.
• Possible medication assessment – only if the above is not enough does a doctor weigh the pros and cons. If melatonin is considered, it is the doctor who decides suitability, dose and treatment length. The starting point according to the recommendations is the lowest possible dose for as short a time as possible.
• Follow-up and discontinuation – the doctor follows up on the effect and plans how the treatment should be tapered off and reassessed, while the routines continue.

Good questions to ask healthcare: Could there be an underlying cause that should be investigated? Which routines should we try first, and for how long? If medication becomes relevant – how do we follow up and taper off?

Children with special needs (neurodevelopmental conditions, ADHD and autism)

Sleep difficulties are more common in children with neurodevelopmental conditions, such as ADHD and autism. In these cases melatonin may become relevant more often than in other children – but still always as a medical assessment within healthcare, not something to start on your own.

Here too, sleep hygiene and non-pharmacological measures are the foundation and should continue alongside if medication is started. In Sweden, melatonin is subsidised for a defined group – children and young people with ADHD where other measures have not given sufficient effect – and the treatment is managed and followed up by a doctor. If your child has a neurodevelopmental condition and struggles with sleep, the right route is to raise it with the clinic responsible for the child's care, or with your child health centre/health centre.

What the research and authorities say

The prescribing of melatonin to children has increased in Sweden, which several experts feel calls for reflection. With short-term, doctor-led treatment, melatonin is usually well tolerated, but the long-term effects in children are insufficiently studied. Melatonin is a hormone that, besides sleep, also affects glucose metabolism, blood pressure and hormone secretion among other things, which is one of the reasons for caution in children who are still growing and developing.

A recurring point in the recommendations is that medicines can risk masking an underlying cause instead of solving it. That is why investigation, routines and follow-up are so central – and why this is a matter for healthcare to assess in each individual case.

Melatonin for adults – briefly on the difference

For adults, melatonin is available without prescription in lower doses, and the approved claim applies to a shorter time to fall asleep at 1 mg close to bedtime. If you want to read about melatonin for adults – dosage, side effects and use – we have a separate melatonin guide. It is about adults and should not be applied to children.

Summary

For children's sleep, routines and environment are the first choice, and melatonin is a matter for healthcare to assess – never something to start on your own. If you have questions about melatonin for adults, read our melatonin guide.
