Downsides and risks
Theraflu Daytime Severe Cold and CoughDelsym
  • 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 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.
  • 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.
