how much nyquil should an adult take

NyQuil dosing for adults commonly follows a 6-hour interval, with a maximum of 4 doses in 24 hours. A typical adult dose is 30 mL (or 2 capsules) taken by mouth as needed for nighttime symptoms. Do not exceed 120 mL (or 8 capsules) in 24 hours. Always use the dosing device provided and avoid taking more often or in larger amounts than directed on the product label. If you have liver disease, consume alcohol, take other acetaminophen-containing medicines, or are taking certain medications, consult a clinician before use. If symptoms persist beyond a few days, worsen, or you’re unsure about interactions with other medicines, seek medical advice.
