So, do you reach for the pill bottle? And is it safe for kids?
A recent study by the U.S. Centers for Disease Control and Prevention (CDC) shows a 503% increase in pediatric melatonin ingestions from 2012 to 2021.
And for many parents, you may not be sure what the right dosage is, and that can lead to an accidental melatonin overdose. About 94.3% of those ingestions included in the study were accidental.
“A lot of people don’t view herbal supplements or vitamins as having any potential danger,” says pediatrician Gina Robinson, MD. “Because things are natural or because things aren’t prescription medications doesn’t mean that there can’t be some complications or dangers involved with using them.”
Dr. Robinson and pediatrician Timothy Benik, DO, explain the symptoms of a melatonin overdose in children and some alternative methods.
Melatonin, a hormone that’s naturally produced by your body to help calm you down and prepare for sleep, is produced by the pineal gland in your brain.
Melatonin supplements are sold over-the-counter and are available as tablets, liquid, capsules and gummies. But supplements aren’t fully regulated by the U.S. Food and Drug Administration (FDA). So, it’s important that you talk to your child’s pediatrician before using melatonin, says Dr. Benik. A provider can help determine the best dosage for your child and discuss any potential side effects.

Melatonin is usually well-tolerated but here are some signs of an overdose to watch out for:
“If a dose is too high or a child doesn’t tolerate melatonin well, parents can be alarmed at the symptoms,” says Dr. Benik.
Typically, most symptoms will resolve on their own.
“But if you’re concerned, the best thing to do is to call your local poison control center and get advice for the situation that you’re in,” advises Dr. Robinson.
In some cases, a melatonin overdose may be a more serious situation. The CDC study says about 1.6% or 4,555 children needed medical attention.
“Overall, this is very rare,” notes Dr. Benik. “It’s very hard to overdose on melatonin to a significant consequential extent.”
If your child is having trouble falling or staying asleep, before you turn to melatonin, Dr. Robinson and Dr. Benik both suggest speaking with your child’s pediatrician.
“I really stress that routine behavioral change be made first,” says Dr. Robinson.
Changes can include establishing (and following) a bedtime routine, teaching your child to self-soothe and including a transition period before bed (reading a book, taking a hot shower).
“Then you can start adding 1 milligram of melatonin, giving it at least one-and-a-half to two hours before you want your child to actually be asleep,” she says. “Because it takes time to actually get through the bloodstream and get to the brain and start to work.”
A pediatrician can also help determine if there are any other underlying causes that affect your child’s ability to sleep.
“Other sleep issues can include obstructive sleep apnea or tonsillar hypertrophy,” says Dr. Benik.
And how long and how often you use melatonin as a sleep aid for your child matters as well.
“I encourage parents to use it for only a short period of time — maybe a month or two — while they’re trying to readjust their patterns and behaviors,” says Dr. Robinson.
Overall, melatonin can be safe. But it’s important for parents to work on other behavioral changes, pay attention to the melatonin dosage they’re giving their children and keep an eye open for any overdose symptoms.
“Even though sometimes melatonin can be helpful, we always want to make sure that we’re not giving too much,” says Dr. Robinson.
