Pediatricians frequently recommend melatonin for children with sleep difficulties, or mothers might try it themselves. However, the proper use of melatonin is frequently misunderstand. 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 yarn I been able to find children coming to Sleep Clinic is that many or all of them have been on melatonin at some phase, or are taking it currently. Melatonin is an important tool in the treatment of sleep disorders in children, and because it is naturally derived, 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 marketings have doubled in the past ten years, increasing from $90 million in 2007 to $260 million in 2012. I worry that the widespread availability of melatonin has led to some parents utilizing it as a shortcut to good sleep practices. An article in the Wall st. Journal( which also 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, restriction sweets, etc ., etc. Well, for whatever reason, “thats really not” our strong suit. This 1 mg sun dosage of melatonin is very helpful winding our kids down and getting them prepared for bed.
In one involve it is safe — unlike many other medications which make you to fall asleep, you cannot overdose on it. However, parents need to know that melatonin is a hormone with consequences 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 countries or Australia.
NOTE:For the vast majority of kids, I recommend behavioral interventions to treat insomnia, commonly referred to as sleep training. I made a guidebook comparing my favorite sleep civilize techniques to help you figure out the best method for you and your child. Start there before trying melatonin.

It’s hard to know for sure. A recent clause the New York Times, ” Parents Are Relying on Melatonin to Help Their Kids Sleep. Should They ?” , include an indication that melatonin marketings 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 impression in everyone. Merely the chronobiotic consequence occurs in all individuals. The natural rise of melatonin grades 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 signifies 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 applied clinically( 0.5 -10 mg or higher) greatly outperform the amount exuded in the body.
There are a few things to be aware of 😛 TAGEND
Blue-white ignited exposure in the evenings alter 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 entails no light emitting 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 fixes and using software to reduce the blue sun 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 necessitates is that the timing of giving melatonin influences both the quantity and direction of the impacts. Many people do not realize that the optimal time to dose melatonin for altering 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 stage syndrome) may actually have a later shift in their sleep planned if “thats really not” dosed accurately. Thus I would leave the timing of that is something that a sleep physician. Jet lag is a similar case[ 1 ]. “All natural” melatonin is from cow or pig psyches and should be avoided. Most plannings around now are synthetic, which is preferable.
Here’s a short video I put together to explain how when you give the melatonin dose really 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 medications 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 no large pharmaceutical corporation bankrolling larger and long-term studies( more on this below). Rather it is regulated as a meat supplement by the FDA. For a terrific examine, 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 around chronic impediment falling asleep within 30 minutes of an age-appropriate bedtime. [ 2 ] Use of melatonin outcomes in less difficulty with falling asleep, earlier time of sleep onset, and more sleep at night. The initial studies used somewhat high dosages, but later studies comparing different doses goes to show that dosage 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 dosages are appropriately above the amount grown naturally in “their childrens”. Timing between 6-7 PM was more effective than later dosages. 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 questions are common in children with autism. Multiple types of problems result, including prolonged time to fall asleep, less sleep on the night, and problems with nocturnal and early morning arouses. Some children with autism have been reduced levels of melatonin as well as decreased discrepancy in melatonin secretion throughout the day. Because of this, melatonin has usually implemented in autistic children, which seems to result in less difficulty falling asleep and more sleep at night. Some studies employed immediate liberate plannings, 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 improvement in other regions in some children- specifically, communication, social withdrawal, stereotyped behaviors, and anxiety.
A recent experiment looked at a time liberated 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 minutes 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 management project. For pediatricians, there is a great practice pathway which suggests the add-on of drug only after a behavioral intervention has neglected. Two great resources for households are the Autism Speaks Sleep Toolkit, and the book Solving Sleep Problems in Children with Autism Spectrum Disorders: A Guide for Frazzled Household( affiliate link ). Here is a terrific review article on this subject as well.
A long acting 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 treatment; it is not yet available for clinical use in the USA.
ADHD and Melatonin
Attention deficit hyperactivity( ADHD) is commonly associated with sleep questions, just as sleep difficulties can cause attentional issues. As many as 70% of children with ADHD may have sleep problems. Sleep difficulties 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 consequences reported included problems with waking up at night and daytime sleepiness in some children. There is a nice review article here.
Delayed Sleep Phase Syndrome and Melatonin
Delayed sleep phase syndrome( DSPS) is a common disorder in teens, where their natural sleep date is altered significantly later than the schedule which its strong commitment( usually school) mandatories. Thus, teens with this disorder an unable to fall asleep by 1-2 AM in the morning or even later. I have determined kids who are routinely falling asleep between 4-5 AM. Melatonin has a clear role in this disorder, as tiny doses 3-4 hours earlier than sleep onset( along with light exposure restraint, sleep hygiene measurements, and gradual changes in schedule[ chronotherapy ]) can be effective in managing this disorder. The reason for the postponement is a marked delay in the DLMO, so melatonin dosing can move sleep periods earlier. For children with DSPS, imparting a dosage 4-6 hours prior to the current time of sleep onset, then moving it earlier every 4-5 days, is recommended, with low-toned dosage formulations. 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. However, in some children melatonin use induced persistently high-pitched 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 disorders. 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 skin and kids with it can have problems with insomnia and non-restorative sleep. Some research has suggested that children with eczema may have low-spirited melatonin levels, and a recent experiment have shown that melatonin may be useful.
It sounds great. Why should I have concerns about melatonin? NOTE:For the overwhelming majority of children, I recommend behavioral interventions to treat insomnia, commonly referred to as sleep training.

There are several fields for concern, specifically known and theoretical side effects, and problems with preparations.
Side consequences( 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 impacts are generally mild, and in my practise merely the morning drowsiness seems to be significant. It can also interact with other medications( oral contraceptive, fluvoxamine, carbemazepine, omeprazole, and esomeprazole, to identify a few cases ). Side effects( 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 tested as closely as a pharmaceutical as the FDA regulates it as a food 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 named 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 absorbs may vary. 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 mothers think it is 1 mg/ dropperful.
This necessitates there is substantially less regulatory oversight in terms of safety and efficacy . I likewise find that the labelling of plannings is often misinforming. Take the instance of this liquid planning, 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 indicated 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 plenty to lot 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, the researchers discovered 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 for 2 years, and did not show any evidence of effects on weight, height, 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 significant damage. However, 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 reading if it is still really necessary. Try to use it as needed as opposes it nightly. Also, I would take a hard look at sleep hygiene and ensure that you are ensuring good bedtime procedures such as a high quality bedtime routine and avoidance of screen occasion for at least an hour prior to bedtime. I would try to reduce the dose, and potentially only use it as necessary as opposed to nightly.
My physician 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. Result modification depending on when you devote 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 planneds is likely to be flip-flop to a daytime sleep schedule) dosing may the opposite influence. This is a special case and should be addressed with your physician. A couple of rules of thumb.
Timing: For shifting sleep schedules earlier 3-6 hours before current sleep onset is best. For the sleep onset influences, 30 times before bedtime is recommended. Remember , not every child gets sleepy with melatonin. Dosing: In general, I would start at a low-toned dose( 0.5 -1 mg) and increase gradually. Recognize that melatonin, unlike other drugs, is a hormone, and that lower dosages are sometimes more effective than higher ones, specially if the benefit of it reduces with day. 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 questions via behavioral modifications. Treatment options are limited. There are no FD-Aapproved insomnia drugs for children except for chloral hydrate which is no longer available. Personally, I use it usually in my practise. It is very helpful for some children and families. I realize Dr. Kennaway’s concerns but I have determined first hand the consequences of poor sleep on children and households. I ever investigate to made to ensure that I am 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 medications. I know that this is the goal of mothers as well. Some children, especially 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 alterations alone have been ineffective Other medical causes of insomnia have been ruled out Your physician thinks that melatonin is a safe alternative for your child and is willing to follow his or her insomnia over time
By the space, here’s a great section from the Chicago Tribune on alternatives to melatonin.

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 famed” Bob from Pharmacy “)for his assistance with this.
If you are interested in more information on this I recommend this Cochrane review on the topic, 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 questions for at least a year for at least four nighttimes per week. The initial tests both put-upon 5 mg around 6 PM. A later test tried multiple dosages. 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 ].
