Tetrahydrozoline is widely believed to cause violent diarrhea if administered orally, as in a few drops of Visine in an unsuspecting person's beverage. However, this is an urban legend, and the actual results may vary from severe nausea and vomiting to seizures or a coma.^[1] Diarrhea is not a side effect.
