my friend took some DayQuil that has been in his hot car for a week already and he says his pupils are dialated and not sure why he is having that reaction to it , he never has had this problem before
Dayquil is definitely affected by sitting in the heat of a car for a week. It should not be consumed because the makers insist that it be kept out of the heat. A car increases the heat temperature. At healthgrades dot com, it says that the cough medicine without being in heat can cause pupils to dilate. They will return to normal when the cough medicine wears off.
