Melatonin is a hormone that regulates sleep-wake cycles, while cough syrup often contains active ingredients like dextromethorphan or guaifenesin to suppress cough or alleviate congestion. There is generally no known interaction between melatonin and most cough syrups, but combining them may lead to increased drowsiness. It's always advisable to consult with a healthcare professional before mixing medications to ensure safety and efficacy.
