When melatonin may help children

The AASM's 2022 health advisory says melatonin can improve sleep in children whose body clocks are off schedule and in some children with developmental problems. The NCCIH also lists some sleep disorders in children among the conditions melatonin may help.

Melatonin is the second most popular natural product parents give children, after multivitamins, according to the AASM. But many sleep problems can be better managed with changes in schedules, habits or behaviors.

What sleep doctors advise

The AASM notes melatonin is a dietary supplement, not under FDA oversight like over-the-counter or prescription medicines. A USP Verified Mark shows a product was made under good manufacturing practices and contains the labeled amount without harmful levels of certain contaminants, but the AASM noted only four melatonin products, all 3 mg or 5 mg, had earned it at the time.

Label accuracy is a real problem

• Wide variation. In one study cited by the AASM, melatonin content ranged from less than half to more than four times the labeled amount. The most variability was in chewable tablets, the form children most often use.
• Gummies. The NCCIH reports a 2023 study in which 22 of 25 melatonin gummy products were mislabeled, ranging from 74% to 347% of the label.
• Other chemicals. Some products contained substances that require a prescription, and a 2017 study found serotonin in 26% of products.

Safety and side effects in children

• Short term. The NCCIH says normal doses appear safe for most children short term, but there are few studies and little long-term information.
• Hormones. Because melatonin is a hormone, it could possibly affect puberty, menstrual cycles or prolactin, though this is not known for sure.
• Side effects. Usually mild: drowsiness, more bedwetting or evening urination, headache, dizziness and agitation.
• Overdose risk. Poison center reports for people 19 and younger rose from 8,337 in 2012 to 52,563 in 2021, with most hospitalizations in teens who took intentional overdoses.

Store it like medicine

A CDC report estimated about 11,000 emergency visits from 2019 to 2022 for children 5 and younger who swallowed melatonin unsupervised. Gummies were the most documented form, and many cases involved bottles children opened. Melatonin products do not require child-resistant packaging, so choose one that has it and close it every time.

About half of those visits (52.4%) involved children aged 3 to 5, and more than a third involved access to 10 or more gummies or tablets. Most (93.5%) did not lead to hospitalization, and a poison center study found 98% of children's melatonin exposures caused minimal or no effects. Even so, every accidental ingestion is avoidable with locked or high storage.

If your pediatrician recommends melatonin

• Use the dose and timing they set. For example, Nature Made's Kids First Sleep gummy, for example, contains 1 mg, with directions for ages 4 to 18 to chew 1 gummy 30 to 60 minutes before bed.
• Look for USP Verified or other independent testing.
• Ask about adult products. The CDC found nearly half of young children's emergency visits involved adult or family formulas.
• Keep working on habits. The AASM says schedule and habit changes often help, and the NCCIH notes light at night can block the body's own melatonin.
