So, can you mix alcohol and Dayquil? The following highlights some of the possible dangers if you mix alcohol and Dayquil.

Because of how commonly Dayquil is used, it’s not unusual for people to wonder “can you mix alcohol and Dayquil,” and the answer is no. Alcohol and Dayquil should not be mixed with one another, and one of the primary reasons this is true is because Dayquil contains acetaminophen.

If you take too much acetaminophen, it can cause liver damage and even acute liver failure. People die from taking medicines with too much acetaminophen, without even realizing they’re putting themselves at risk.

Even if you don’t mix alcohol and Dayquil, but you take more of the medicine than what’s instructed, you’re at risk of liver toxicity from acetaminophen.

If you do mix alcohol and Dayquil, your risk of liver problems goes up even more. When you combine alcohol and Dayquil or alcohol with any substance that affects the liver, you are greatly increasing your chances of acute liver failure. It’s possible for liver damage to occur with only 2,600 mg of acetaminophen in a day if you also consume alcohol, and this isn’t nearly as much acetaminophen as you might think.

If you regularly consume alcohol, it’s recommended that you take no more than 2,000 mg of acetaminophen in a day, but ideally, your intake should be lower than that. To put this in perspective, extra-strength Tylenol has 500 mg of acetaminophen, so you shouldn’t have more than two to four extra strength pills in a 24-hour period if you drink alcohol. One tablespoon of Dayquil has around 325 mg of acetaminophen.

Some of the possible warning signs of an overdose resulting from combining alcohol and Dayquil include urine problems, abdominal pain, nausea or vomiting, irregular heartbeat, itchiness, stools that are the color of clay, anxiety or vertigo.

While the risks of liver damage and acute liver failure are one of the primary reasons you should never combine alcohol and Dayquil, there are others as well.

When you combine alcohol and Dayquil, it can impair your thinking to the point that you shouldn’t operate machinery or a vehicle. It can also lead to mood changes, hallucinations, and confusion.

People who mix alcohol and Dayquil may experience dizziness, concentration and judgment problems, and drowsiness as well.

These specific symptoms of alcohol and Dayquil are primarily the result of the dextromethorphan contained in this medicine. This substance has an effect on the central nervous system in a similar way to alcohol, so the effects are amplified.

If you do mix alcohol and Dayquil, you can become so impaired that you find yourself in dangerous situations, or you put others in danger.

So, to sum up, can you mix alcohol and Dayquil? While you should always ask your physician any questions you have about medicines and their interaction with alcohol, the best advice is no; you shouldn’t mix alcohol and Dayquil. The most severe possible side effects can come from the interaction of the alcohol and Dayquil on the liver. Too much acetaminophen can cause liver damage or acute liver failure, and that can be amplified with alcohol.

There is also the possibility that because of the effects on the central nervous system of alcohol and Dayquil you could become dangerously impaired.

If you have any more questions about the interaction between alcohol and Dayquil you should speak with your doctor or a pharmacist.
