More than 260,000 cases of melatonin intake were documented, with more than 27,000 children requiring hospitalization. This includes almost 4,000 children who were hospitalized and roughly 290 children who were treated in an intensive care unit. Five of the children were placed on mechanical ventilation for breathing assistance, and two died before the age of two. Since 2012, hospitalizations and other adverse consequences associated with pediatric melatonin intake have increased, owing mostly to an increase in children aged 5 and younger mistakenly taking the medicine. These findings were published Thursday (June 2) in the Centers for Disease Control and Prevention's (CDC) Morbidity and Mortality Weekly Report (opens in new tab). "Public health initiatives should focus on raising awareness of the growing number of melatonin ingestion among youngsters and developing preventative methods to reduce this danger, the study's authors stated. Melatonin is a hormone generated by a gland in the brain that aids in the regulation of the body's 24-hour circadian rhythm and sleep-wake cycle, as previously described by Live Science. Synthetic melatonin is sold over-the-counter in the United States as a sleep aid for both adults and children. Melatonin products are subject to less regulatory supervision than prescription pharmaceuticals, since they are categorized as "dietary supplements" by the Food and Drug Administration (FDA). Because the FDA does not confirm the label's veracity, the concentration of melatonin in a product may differ from what is reported on the bottle. A 2017 research published in the Journal of Clinical Sleep Medicine discovered that, at least in Canada, the concentration of melatonin in a supplement frequently differed much from what was indicated, and Canada eventually banned OTC melatonin owing to quality control difficulties. This lack of quality control, along with the supplement's growing popularity, may raise the danger of youngsters eating excessive quantities of melatonin, the scientists said. Furthermore, according to the Mayo Clinic, the same 2017 study discovered that certain melatonin supplements include clinically significant quantities of serotonin, which serves as a chemical messenger in the brain and can have serious adverse effects if taken in excessive concentrations. The authors of the new study examined calls to poison control centers in the United States between 2012 and 2021 and calculated the number of "melatonin ingestion" recorded in children, adolescents, and young adults aged 19 and under. The recorded number of ingestion climbed from 8,300 in 2012 to 52,500 in 2021. The greatest year-to-year rise occurred between 2019 and 2020, when the rate of reporting increased by around 38%. Unintentional ingestion were the key drivers of this rise," the study's authors stated. "This might be connected to greater melatonin accessibility during the pandemic, since youngsters spent more time at home due to stay-at-home orders and school closures." The vast majority of reported ingestion were unintentional, including male youngsters aged 5 and less. While the majority of cases were asymptomatic and treated at home, a few of them resulted in serious outcomes such as high fever, respiratory failure requiring intubation, and seizures, some of which resolved quickly and others that progressed to "status epileptics," a long-lasting seizure that can lead to permanent brain damage or death, according to the authors. According to Boston Children's Hospital, there is no official study on the potential adverse effects of children utilizing melatonin as a sleep aid (opens in new tab). However, the supplement's prescribed levels appear to have little or no short-term negative effects, and if side effects do occur, they tend to be moderate. Headaches are a common adverse effect.
