Pediatricians frequently recommend melatonin for children with sleep questions, or parents might try it themselves. Nonetheless, the proper use of melatonin is often misunderstood. Here is a practical guide for parents and pediatricians to decide if a child should try it, and to understand how it should be used.
A common weave I been able to find children coming to Sleep Clinic is that many or all of them have been on melatonin at some level, or are taking it currently. Melatonin is an important tool in the treatment of sleep ailments in children, and because it is naturally obtained, there is a widespread perception that it is safe. However, I have become concerned by the frequency of its employ, especially in an unsupervised way.
Melatonin sales have doubled in the past ten years, increasing from $90 million in 2007 to $260 million in 2012. I was concerned that the widespread availability of melatonin has led to some mothers use it as a shortcut to good sleep practices. An article in the Wall st. Journal( which also rendered the sales figures above ), quoted a father’s review on Amazon 😛 TAGEND
OK, yes, as parents my spouse and I should do a better task starting the bedtime routine earlier, turning off the TV earlier, limiting sugaries, etc ., etc. Well, for whatever reason, this is not our strong suit. This 1 mg illumination dosage of melatonin is very helpful winding our children down and getting them ready for bed.
In one see it is safe — unlike many other medications which cause you to fall asleep, you cannot overdose on it. However, parents need to know that melatonin is a hormone with impressions throughout the body and we do not yet know what the long-term effects of melatonin use will be. Many mothers in the US would be surprised to know that melatonin is only available with a prescription in the European Union or Australia.
NOTE:For the vast majority of kids, I recommend behavioral interventions to treat insomnia, commonly referred to as sleep training.

It’s hard to know for sure. A recent section the New York Times, ” Parents Are Relying on Melatonin to Help Their Kids Sleep. Should They ?” , include an indication that melatonin sales overall had increased by 87% in the year prior to March 2020. The Times conducted a survey of 933 parents with children under age 18. One third had a history of sleep impediments in the last year. Over half the parents reported giving melatonin to their children at one time.
What is melatonin? What does melatonin do?
Melatonin is a hormone which is naturally produced by the pineal gland in your psyche. It is both a chronobiotic agent, meaning that it regulates your circadian or body clock; and a hypnotic, means that at higher doses it may induce sleep. Melatonin is usually used for its hypnotic impact, but it does not have this result in everyone. Only the chronobiotic influence occurs in all individuals. The natural rise of melatonin degrees in the body 1-3 hours before sleep onset is known as the “dim ignite melatonin onset”( DLMO ). This is the signal involved in body clock scheduling of sleep and corresponds to the end of the “wakefulness” signal produced by the circadian system. Children with insomnia may be given melatonin after their scheduled bedtime extends; what this intends is that their bodies are not yet ready for sleep. “Thats one” reason why bedtime fading can be so effective for some children. The doses utilized clinically( 0.5 -10 mg or higher) greatly transcend the amount secreted in the body.
There are a few things to be aware of 😛 TAGEND
Blue-white illuminated exposure in the nights shift the DLMO later. This is why bright light exposure in the nights can worsen insomnia. I highly recommend eliminating ANY screen time for preschool through elementary school children for an hour prior to bedtime. That necessitates no light emit Kindles, iPads, smartphones, computers, or( God forbid) television in the bedroom For students in junior high and beyond who need to use computers to complete school work, I highly recommend lowering brightness decideds and using software to reduce the blue illuminate frequencies.( For more on this speak my post about going on a “light diet” here ). The the consequences of dosing melatonin( and light therapy for that matter) are phase dependent. What that entails is that the timing of giving melatonin influences both the importance and future directions of the impacts. Many people do not realize that the optimal time to dose melatonin for changing sleep date is actually a few hours before bedtime- that is to say, before the DLMO. The other facet of this is that in teenagers with severely altered sleep planned( delayed sleep period disorder) may actually have a later shifting in their sleep schedule if this is not dosed accurately. Thus I would leave the timing of this to a sleep physician. Jet lag is a similar case[ 1 ]. “All natural” melatonin is from cow or pig brains and should be avoided. Most preparations around now are synthetic, which is preferable.
Here’s a short video I put together to explain how when you give the melatonin dose actually matters.( Maybe just for the supernerds out there like myself ).
How effective is melatonin for sleep difficulties in children?
The overall effects of melatonin include falling asleep more quickly and an increase in sleep time. Like all drugs used to help children fall asleep, there is fairly limited information available. This means that most studies have small groups followed for short periods of time. Furthermore, melatonin not regulated as a pharmaceutical in the U.S. Thus, there is nothing large-scale pharmaceutical company bankrolling larger and long-term studies( more on this below). Rather it is regulated as a meat supplement by the FDA. For a terrific review, including dosing recommendations, I highly recommend this article by Bruni et al.
Chronic sleep onset insomnia and Melatonin:
Problems with falling asleep are common in children, just like in adults. In children with chronic difficulty falling asleep within 30 times of an age-appropriate bedtime. [ 2 ] Use of melatonin results in less difficulty with falling asleep, earlier time of sleep onset, and more sleep at night. The initial studies employed fairly high doses, but later studies comparing different doses goes to show that dose didn’t matter, and that the lowest dose studied was as effective as the highest.[ 3 ] This is likely due to the fact that ALL these doses were well above the amount rendered naturally in “their childrens”. Timing between 6-7 PM was more effective than later doses. The authors point out that a midafternoon dose would have the best effect( due to the phase response curve) but that afternoon dosing would have the unpleasant side effective of establishing children sleepy in the afternoon.( For more info, read here and here and here ).
Autism and Melatonin
Sleep problems are common in children with autism. Multiple types of difficulties arise, including prolonged time to fall asleep, less sleep during the night, and problems linked to nocturnal and early morning arouses. Some children with autism have decreased levels of melatonin as well as declined discrepancy in melatonin secretion throughout the day. Because of this, melatonin has commonly been used in autistic children, which seems to result in less difficulty falling asleep and more sleep at night. Some studies use immediate freeing formulations, whereas others use long behaving forms of melatonin. The majority of studies involved melatonin dosing 30-60 minutes prior to bedtime. Interestingly, these studies also demonstrated the process of improving other realms in some children- specifically, communication, social withdrawal, stereotyped behaviors, and anxiety.
A recent experiment looked at a time released melatonin preparation called PedPRM at doses of 2-5 mg . The children in this trial slept 57.5 times more( compared with the children who did not receive the drug, who slept 9 times more ). Most of the benefit seemed to be due to improvement in falling asleep- on average, treated children fell asleep 39 times faster. This drug is still not approved by the FDA but is in the pipeline for approval.
As in other children, melatonin should be added to a behavioral administration project. For pediatricians, there is a great practice pathway which suggests the add-on of drug merely after a behavioral intervention has failed. Two great resources for families are the Autism Speaks Sleep Toolkit, and the book Solving Sleep Problems in Children with Autism Spectrum Disorders: A Guide for Frazzled Household( affiliate associate ). Here is a terrific review article on this subject as well.
A long behaving figure of melatonin has shown great promise for children with autism, with children in a 2017 test sleeping a whopping 57.5 minutes later per nighttime with care; it is not yet available for clinical use in the USA.
ADHD and Melatonin
Attention deficit hyperactivity( ADHD) is commonly associated with sleep difficulties, just as sleep questions can cause attentional issues. As many as 70% of children with ADHD may have sleep problems. Sleep troubles include difficulty falling asleep, abnormalities in sleep architecture( e.g. the proportions of different stages of sleep ), and daytime sleepiness. Tests of melatonin( in dosages ranging from 3-6 mg) showed that it helped children with ADHD to fall asleep more quickly, although there was no evidence of improvement in attentional symptoms during the day. Side influences reported included problems with waking up at night and daytime sleepiness in some children. There is a nice review article here.
Delay Sleep Phase Syndrome and Melatonin
Delayed sleep phase syndrome( DSPS) is a common disease in teens, where their natural sleep date is changed significantly later than the schedule which their commitments( generally academy) mandates. Thus, teens with this disorder an unable to fall asleep by 1-2 AM in the morning or even later. I have learnt kids who are routinely falling asleep between 4-5 AM. Melatonin has a clear role in this disorder, as small-time doses 3-4 hours earlier than sleep onset( together with light exposure limit, sleep hygiene quantifies, and gradual changes in schedule[ chronotherapy ]) can be effective in managing this disease. The reason for the postponement is a marked delay in the DLMO, so melatonin dosing can move sleep intervals earlier. For children with DSPS, devoting a dose 4-6 hours prior to the current time of sleep onset, then moving it earlier every 4-5 periods, is recommended, with low dose preparations. Of all the conditions mentioned here, this has the clearest benefit from melatonin. Here is a terrific review article.
Children With Neurodevelopmental Delay and Melatonin
Children with various causes of neurodevelopmental delay may have substantial insomnia and melatonin may help. Nonetheless, in some children melatonin use induced persistently high daytime blood levels of melatonin( and daytime sleepiness ).
Blindness and Melatonin
Some children with blindness may have issues with sleep wake time as they do not have light regulating their circadian clock and may thus develop sleep ailments. Very small-scale trials in adults have shown benefit( here’s one) but the data is very limited.
Eczema and Melatonin:
Eczema is associated with dry, itchy scalp and kids with it can have problems with insomnia and non-restorative sleep. Some research has suggested that children with eczema may have low-pitched melatonin levels, and a recent test have shown that melatonin may be helpful.
It sounds great. Why should I have concerns about melatonin?

There are several fields for concern, specifically known and theoretical side effects, and problems with preparations.
Side results( known ): In the short-term, melatonin seems to be quite safe. Unlike many other sleep inducing agents, “no serious safety concerns have been raised”( from Bruni review below ). The most common side effects include morning drowsiness, bedwetting, headache, dizziness, nausea, and diarrhea. These results are generally mild, and in my practise only the morning drowsiness seems to be significant. It can also interact with other drugs( oral contraceptive pill, fluvoxamine, carbemazepine, omeprazole, and esomeprazole, to name a few cases ). Side influences( theoretical ): Melatonin given to children may lead to persistently elevated blood melatonin grades throughout the day. This can be associated with persistent sleepiness, but the other results are unclear. It is important to know that melatonin has NOT been experimented as closely as a pharmaceutical as the FDA governs it as a meat supplement. The studies following children who have been using melatonin long-term have relied mainly on parental reports as opposed to biochemical testing. A physician in Australia called David Kennaway has published two editorials this year pointing out the inadequacy of information on long-term use in children.( You can speak these here and here ). He states his point of view in a pithy way ]”
…parents should ever be informed that( 1) melatonin is not registered for use in children,( 2) no rigorous long-term safety studies have been conducted in children and by the way( 3) melatonin is also a registered veterinary drug used to alter the reproduction of sheep and goats .”
Problems with preparations- poor labeling: Melatonin preparations have been shown have to variable concentrations from preparation to preparation. Moreover, the amount that a child’s body assimilates may differ. Remember how I told you that melatonin was treated as a food supplement by the FDA? This is a common planning . . . . . . but the label is not clear that it is 0.25 mg in each dropperful. Many parents think it is 1 mg/ dropperful.
This signifies there is substantially less regulatory oversight in terms of safety and efficacy . I likewise find that the labelling of formulations is often misleading. Take the lesson of this liquid preparation, which many of my patients have tried. It is labeled as “1 mg” but each dropperful contains 0.25 mg.
You need to go to the web to get this information as it is not on the bottle.( It may be in the package insert, but I suppose few people read these ). Problems with formulations- incorrect dosing: A recent study depicted that the amount of melatonin can differ anywhere from -8 3% to +478% from the labeled dose. This means that if you are giving your child a dosage of 3 mg, the actual dose may actually be anywhere from 0.5 mg to 14 mg. Furthermore, the lot to plenty variability was as high-pitched as 465%- meaning that you may buy a different bottle of medication, from the same manufacturer, and still one bottle may have more than four times as much as melatonin as another, Finally, health researchers noted serotonin( a medicine used in other conditions, and likewise a neurotransmitter) in 71% of samples. To me, this is the most concerning issue with melatonin- you don’t know what you are getting.
A 2020 study of the PedPRM long behaving melatonin formulation followed 80 children around 2 years, and did not show any evidence of effects on load, altitude, torso mass indicator, or Tanner staging( a measure of sex developing ). This is the best long term study of melatonin safety and is quite reassuring.
My child is already on melatonin. Do I need to freak out?
I don’t think so, as there is little concrete evidence of substantial harm. Nonetheless, if you started melatonin on your own I beg you to discuss it with your child’s physician to see if it is really necessary. If your child has been using it long-term and sleeping well, you can consider slowly reducing the dose and appreciating if it is still really necessary. Try to use it as needed as opposes it nightly. Also, I would take a hard-handed look at sleep hygiene and ensure that you are ensuring good bedtime procedures such as a high quality bedtime routine and avoidance of screen time for at least an hour prior to bedtime. I would try to reduce the dose, and potentially merely use it as necessary as opposed to nightly.
My doctor and I has spoken about it. What should we consider regarding how and when to give melatonin?
Melatonin can be a tricky medication to dose. Impact alteration will vary depending on when you afford it compared to your child’s usual sleep planned. Thus, a small dose a few hours before bedtime can have more of an effect than a large dose given at bedtime. In some situations( as with people whose sleep schedules is likely to be flip-flop to a daytime sleep schedule) dosing may the opposite effect. This is a special case and should be addressed with your physician. A couple of rules of thumb.
Timing: For shifting sleep planneds earlier 3-6 hours before current sleep onset is best. For the sleep onset effects, 30 times before bedtime is recommended. Remember , not every child gets sleepy with melatonin. Dosing: In general, I would start at a low-spirited dose( 0.5 -1 mg) and increase slowly. Recognize that melatonin, unlike other medications, is a hormone, and that lower doses are sometimes more effective than higher ones, specially if the benefit of it reduces with time. Good Sleep Hygiene is Critical: Melatonin is not a substitute for good sleep hygiene practices and should only be used in concert with a high quality bedtime, limitation on light exposure, and an appropriate sleep schedule. When possible, purchasing a USP Verified preparation may indicate that the product is manufactured to the requirements of the U.S. Pharmacopeial Convention, which could mean that the quality controllers are tighter.
What is the take home? Should my child take melatonin?
I have not met a parent who is eager to medicate their child. Such decisions are made with a lot of soul-searching, and frequently after unsuccessful attempts to address sleep difficulties via behavioral changes. Treatment options are limited. There are no FD-Aapproved insomnia medications for children except for chloral hydrate which is no longer available. Personally, I use it commonly in my practice. It is very helpful for some children and families. I appreciate Dr. Kennaway’s concerns but I have determined first hand the consequences of poor sleep on children and families. I ever investigate to make sure that I is definitely not missing other causes of insomnia( such as restless leg syndrome ). My end goal is always to help a child sleep with a minimum of drugs. I know that this is the goal of mothers as well. Some children, particularly those with autism of developmental issues, will not be able to sleep without medication. So, melatonin may be a good option for your child if 😛 TAGEND
Behavioral varies alone have been ineffective Other medical causes of insomnia have been ruled out Your physician thinks that melatonin is a safe option for your child and is willing to follow his or her insomnia over occasion

So, this has been quite a long post. Do you have questions about melatonin use in children and teens? What has your experience been?
A special thanks to Bob Young R.Ph( aka the legendary” Bob from Pharmacy “)for his assistance with this.
If you would like more information on this I recommend this Cochrane review on special topics, and this WebMD article. An age appropriate bedtime was defined as 8: 30 PM+ 15 times x( age in years- 6 ). These children had had difficulties for at least a year for at least four nighttimes per week. The initial experiments both ill-used 5 mg around 6 PM. A later experiment tried multiple doses. Interestingly, the dose did not matter, and the lowest dose( 0.05 mg/ kg of the child’s weight) was equally effective.[ So, for a 40 lb child- 40/2.2= 18. 2 kg. 18.2* 0.05 mg/ kg= 0.91 mg ].
