NyQuil can generally be taken every 4 to 6 hours as needed for symptom relief, but not more than four doses in 24 hours. The typical adult dose in liquid form is 30 mL (or 2 tablespoons) every 6 hours, and for capsules, it is usually 2 capsules every 6 hours. It is important not to exceed four doses in a 24-hour period to avoid potential liver damage and other serious side effects. Additionally, follow the dosing instructions on the product packaging or as directed by a healthcare professional. If symptoms persist or worsen, consult a healthcare provider.
