    Get advice promptly, even if the amount is uncertain

    In the United States, call Poison Help at 1-800-222-1222. For severe symptoms such as impaired breathing, a seizure or inability to wake, call 911. Do not make the child vomit. Outside the United States, use the local poison service or emergency number. [1]

    Report the product, not just the number of gummies

    Have the container available and describe the child’s age, the possible amount, timing and symptoms. Products differ in strength and may contain other ingredients. NCCIH also warns that melatonin products may not match their label amounts, so a guessed gummy count cannot establish that an exposure is harmless. [2][1]

    Watchfulness does not replace a triage decision

    Sleepiness, headache, nausea or agitation can occur after excess melatonin. A child seeming merely sleepy is not a reason to ignore difficulty waking or abnormal breathing. Follow the poison specialist’s specific observation or evaluation instructions rather than applying another family’s online experience. [3]

    Use an uncertain count as information, not reassurance

    Imagine an open bottle is found with several gummies missing, but nobody knows who ate them. Tell the specialist what is known and what is uncertain. After the immediate situation is addressed, store the product out of children’s sight and reach; gummies should not be presented as candy. [2][1]
