Is it dangerous to drink NyQuil if you drank a beer 2 hours before?

Mixing alcohol with medication (including NyQuil) can be very dangerous. Alcohol can interact with the medication changing how your body responds to it, which can cause negative side effects. These side effects can include increased drowsiness, dizziness, and impaired coordination, which can increase your risk of accidents and injuries. In some cases, mixing alcohol and medication can even be fatal. Therefore, it's best to avoid taking any medication, including NyQuil, if you plan to drink alcohol or have recently consumed alcohol. Always read the medication label and follow the instructions for use, and speak to your doctor or pharmacist if you are concerned or have questions.
