DayQuil provides non-drowsy relief from common cold and flu symptoms such as headache, fever, sore throat, cough, nasal congestion, and minor aches. Available in forms like LiquiCaps, liquid, and Severe versions, it combines acetaminophen for pain and fever, dextromethorphan for cough suppression, and phenylephrine for decongestant effects. Some formulations add guaifenesin to loosen mucus.
Proper dosing follows age-specific instructions on the package to avoid risks like liver damage from excess acetaminophen. Adults and older children take it every four hours as needed, with strict limits on daily amounts. Children under certain ages require doctor consultation or avoidance.
This article outlines DayQuil dosages across products and age groups, including a clear chart. It covers administration, benefits, side effects, and precautions based on current guidelines. Always check the label of your specific product and consult a healthcare provider for personalized advice.
Understanding DayQuil Formulations
DayQuil comes in standard Cold & Flu and Severe versions. Standard includes acetaminophen, dextromethorphan, and phenylephrine. Severe adds guaifenesin for chest congestion relief. LiquiCaps offer convenience, while liquid allows precise measurement with the provided cup.
Active ingredients per adult dose vary slightly by form. LiquiCaps typically deliver 650 mg acetaminophen, 20 mg dextromethorphan, and 10 mg phenylephrine per two capsules. Liquid matches this in 30 mL. Severe boosts guaifenesin to 400 mg in some liquids.
Choose based on symptoms—Severe suits thicker mucus or stronger congestion. All versions stay non-drowsy for daytime use.
Recommended Dosages by Age and Form
Adults and children 12 years and older take the standard dose every four hours. Do not exceed four doses in 24 hours to limit acetaminophen intake. Children 6 to 11 years use half the adult liquid dose in some products, but capsules often start at 12 years.
For Severe formulations, dosing aligns similarly but includes the extra expectorant. Under 6 years, most products advise asking a doctor or avoiding use. Under 4 years, do not use without professional guidance.
Always use the provided measuring device for liquids. Swallow capsules whole with water.
