It’s important to note that while DayQuil is non-drowsy, NyQuil is designed for nighttime use and may cause drowsiness, which could be a potential drawback for those who prefer a non-drowsy formula around-the-clock. The product’s 96-count packaging makes it a good option for families or for stocking up in preparation for cold and flu season. As with any medication, it’s essential to follow the recommended dosage and be aware of potential side effects, which can vary depending on individual reactions to the ingredients.
