About NyQuil Cold & Flu Liquid (12oz) — Complete Product Guide
NyQuil Cold & Flu is a multi-symptom nighttime OTC medication that relieves cold and flu symptoms so you can rest and recover overnight. It contains three active ingredients: acetaminophen (pain/fever), dextromethorphan (cough suppressant), and doxylamine succinate (antihistamine/sleep aid). The liquid formulation provides fast absorption and onset of action.
What Conditions Does NyQuil Cold & Flu Treat?
NyQuil Cold & Flu is indicated for the relief of nighttime relief of cold and flu symptoms including fever, sore throat, cough, nasal congestion, runny nose, sneezing, headache, and minor body aches. It is approved for OTC use and does not require a prescription for standard adult doses.
How Does NyQuil Cold & Flu Work?
NyQuil's three-ingredient formula works synergistically. Acetaminophen reduces fever and relieves sore throat pain and body aches. Dextromethorphan (DXM) suppresses cough by acting on the cough center in the brain. Doxylamine succinate, a sedating antihistamine, relieves runny nose and sneezing while also promoting sleep — allowing your body to rest and heal overnight. Onset is typically 30 minutes.

Adults and children 12 and over: Take 30mL (2 tablespoons) every 6 hours as needed. Do not take more than 4 doses in 24 hours. Do not take with other medications containing acetaminophen. Use the measuring cup provided. Do not exceed the recommended dose. Contains sedating antihistamine — do not drive or operate machinery after use.

How long does NyQuil make you sleep?
The doxylamine in NyQuil causes drowsiness that typically lasts 6–8 hours. It is designed for bedtime use only — do not take when you need to be alert. The antihistamine effect helps you rest through uncomfortable cold and flu symptoms overnight.
Can I take NyQuil with other cold medications?
Be very careful — NyQuil contains acetaminophen. Do not combine with Acetaminophen (Tylenol), other multi-symptom cold products, or pain relievers containing APAP. Check all labels. For daytime, use DayQuil LiquiCaps instead.
Can I drive after taking NyQuil?
No. NyQuil contains doxylamine, a sedating antihistamine. Do not drive, operate machinery, or perform tasks requiring alertness after taking NyQuil. It is designed for bedtime use only.
What is the difference between NyQuil and DayQuil?
DayQuil is for daytime use — it does not contain the sedating antihistamine doxylamine. DayQuil relieves congestion, cough, and fever without causing drowsiness. NyQuil adds the sleep-aid ingredient for nighttime use.
