Upsides
  • Good for treating dry cough.
  • Available in drugstores either by itself or in combination with other medications to treat cold and allergy symptoms.
  • Available as a liquid and a tablet.
  • Some products relieve cough for up to 12 hours.
  • Nyquil Cold And Flu (Acetaminophen / Dextromethorphan / Doxylamine) is a combination medicine that relieves multiple cold symptoms. It's good to use if you have watery eyes, a cough, fever, and pain.
  • The cough medicine (dextromethorphan) works well and has very few side effects.
  • The pain reliever (acetaminophen) is easier on your stomach and has fewer drug interactions than other pain medications like aspirin or ibuprofen.
  • The antihistamine (doxylamine) will help you sleep.
Downsides
  • 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.
  • 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.
