[/INST] Hi, NyQuil which consists of acetaminophen, dextromethorphan, and dopamine) is commonly used to treat headaches, fever, cough, runny nose, sneezing, and sore throat caused by allergies, the common cold, or the flu. There is no documented harmful interactions between NyQuil and Coffee. However, because of safety concerns, it is not advisable to take NyQuil just for the sake of getting some sleep.
