Downsides and risks
DayQuil Cold and Flu
› Can't take dextromethorphan if you're taking MAO inhibitors (drugs used to treat Parkinson's disease, depression, and other emotional conditions). If taken together, they will cause dangerously high blood pressure levels.
› If you're taking this in combination with other cold and allergy medications, you should read labels closely to make sure you're not accidentally taking too much of a single ingredient.
› If you don't really need all of the medications in this combination, you're taking extra medicine and might have extra side effects for no reason.
› Phenylephrine doesn't last as long as other oral decongestants like pseudoephedrine.
› You shouldn't use it if you have high blood pressure.
› To avoid hurting your liver, you have to keep track of the total amount of acetaminophen (APAP) you're taking since it's a very common ingredient in pain and cold/flu combination medicines.
