can you drink while taking dayquil

You should not drink alcohol while taking DayQuil because the combination can strain your liver, increase side effects like drowsiness and dizziness, and in serious cases contribute to breathing problems or liver damage. Most medical and recovery sources recommend avoiding alcohol completely until DayQuil is out of your system, which is usually about 4–6 hours after your last dose, and even then caution is advised if you take repeated doses or drink heavily.

If you have liver disease, drink frequently, or use other medicines with acetaminophen, it is especially important to skip alcohol and talk with a healthcare professional before mixing any amount of alcohol with DayQuil.
