A member asked:
Is it safe to take dayquil with cofee? some say i have to wait 4 hours after coffee before taking dayquil?
A doctor has provided 1 answer
DayQuil contains phenylephrine and you should limit your caffeine intake while taking this medicine as both have similar effects. Limiting caffeine intake includes coffee, tea, caffeinated sodas, etc. If there is 4 hours between the coffee and DayQuil, that is probably sufficient time for the caffeine’s effects to be gone. Good luck!
