Does the Wedding Crashers Visine prank actually work?
Rather something else: A common urban legend is that a few drops of Visine in an unsuspecting victim’s drink will cause a harmless bout of diarrhea. This will not produce diarrhea, but oral administration of Visine can induce dangerous side effects related to Visine’s ingredient tetrahydrozoline hydrochloride such as: * Dangerously low body temperature (hypothermia) * Blurred vision * Nausea and vomiting * Difficulty in breathing or even a complete halt in breathing * Elevating (hypertension) then dropping (hypotension) blood pressure * Possible coma * Seizures and tremors Pfizer recommends that anyone ingesting Visine get medical attention or contact a poison control center immediately.
