NyQuil vs. ZzzQuil

Key Differences

NyQuil is a brand of over-the-counter medication primarily used to treat symptoms of the common cold and flu, such as cough, sore throat, fever, and congestion. ZzzQuil, on the other hand, is formulated specifically as a sleep aid, helping individuals who have difficulty falling asleep.

NyQuil contains active ingredients like doxylamine, dextromethorphan, and acetaminophen, targeting multiple cold and flu symptoms, and often causes drowsiness. ZzzQuil, however, primarily contains diphenhydramine, an antihistamine used to induce sleepiness, without targeting cold or flu symptoms.

While NyQuil is intended for short-term use during a cold or flu, it is not advisable for just sleep issues due to its multi-symptom formula. ZzzQuil is designed for those who need help falling asleep and is not suitable for treating cold or flu symptoms.
