what’s DayQuil and night quill?

From Grok:
DayQuil and NightQuil are over-the-counter medications produced by Vicks, commonly used to relieve symptoms of the common cold and flu. They are part of a line of combination medicines designed to address multiple symptoms at once.

So when you take the two together what happens ?😂

Combining them could lead to too much acetaminophen ( risking liver damage), excessive drowsiness from doxylamine clashing with DayQuil’s stimulant-like decongestant, and amplified side effects like dizziness, dry mouth, or upset stomach.
