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.
