DayQuil And Alcohol
This situation is a bit complicated. If you allow me, I would like to explain it to you.
We stated that there are 3 active ingredients in the drug.
The name of the first ingredient is acetaminophen.
Typically, a normal dose of acetaminophen (no more than 4,000mg per day) after a night of drinking is very unlikely to cause liver damage.
However, heavy alcohol use or very frequent drinking (more than one drink per day for women or more than two drinks per day for men), along with repeated daily doses of acetaminophen, can damage your liver.
Dextromethorphan, the second component in the drug, should not be used with alcohol.
Concomitant use of the dextromethorphan component with alcohol may cause nervous system side effects such as dizziness, drowsiness and difficulty concentrating.
Drinking with alcohol can sometimes even cause deterioration in thinking and judgment.
As a result, you should avoid or limit the use of alcohol while being treated with DayQuil.
Now that we have analyzed the two components, we understand that this drug should not be used with alcohol. Let’s take a look at the last ingredient, phenylephrine.
Consuming alcohol with the Phenylephrine component can cause confusion, dizziness and an increased risk of falls.
