You can take DayQuil every 4 hours as needed, but you should not exceed 4 doses within a 24-hour period. This means a maximum of four doses per day

. For adults and children 12 years and older, the typical dose is 30 mL of the liquid form or 2 LiquiCaps every 4 hours, up to 4 doses daily

. It is important not to exceed this limit because DayQuil contains acetaminophen, and taking more than the recommended dose can lead to serious health risks such as liver damage

. If you are also taking NyQuil, do not exceed a combined total of 4 doses of DayQuil and NyQuil in 24 hours, since both contain acetaminophen and other similar ingredients

. Always follow the package instructions and use the provided measuring tools for liquid doses. If symptoms persist beyond two days or worsen, consult a healthcare professional
