Can you take Dayquil with beer?

You should not drink alcohol when you are sick. Alcohol is a depressant, and it slows down your body's responses. You need all your energy to fight off this cold or flu, and you don't need to use up energy trying to come out of an alcohol stupor!

In addition, Dayquil contains acetaminophen. This drug is known to cause liver damage. Alcohol also causes liver damages. Doctors recommend that you never use alcohol and acetaminophen together.
