Used as directed, they may indeed give you that clear-eyed look but that's mostly due to the constriction of blood vessels in the eye. Internally they also induce vasoconstriction as Toxnet calls it. The resulting symptoms are nothing, nothing at all like the Hollywood version of events.
They include rapid heart beat, nausea, blurred vision, drowsiness, convulsions. The Toxnet entry, based partly on cases of children who swallowed a bottle of eyedrops or nosedrops left carelessly on a table or counter, notes that "drowsiness and mild coma" often alternate with periods of thrashing and hyperactivity. What does this tell us, aside from the obvious home precautionary warnings don't leave your eye drop bottles lying around the house and, by the way don't drink them? The record tells us that tetrahydrozoline while poisonous is not a top-of-line-lethal substance.
LD50 stands for lethal dose 50 percent, meaning the amount of a toxic substance that will kill half of a test population.
And that difference means that while people do end up the hospital, they tend to survive the stay. This is good news for victims and also for perpetrators, as so many of them end up arrested thanks in part to the very characteristic symptoms of eye drop poisoning. Still as I also said earlier this is not really a tale of a classic homicidal poison like cyanide or one of devious plotting. This is more a tale of impulse, of anger, of grabbing a handy bottle.
The active ingredient in Visine eye drops is Tetrahydrozoline HCl 0. Swallowing this substance can result in a number of nasty effects, including:. One thing tetrahydrozoline has not been known to do is to cause sudden onset bouts of severe diarrhea.
Of all the Visine poisoning cases studied by medical observers, we found none that mentioned diarrheal output brought about by the drug. Drinking it can and has caused severe depression of the central nervous system. In , a two-year-old child who ingested at most 2 to 3 mL of Visine eye drops became dangerously lethargic and unresponsive to every stimulus except deep pain.
These medications are available over-the-counter in pharmacies in the United States and are frequently not packaged in child-resistant containers. More than of these products contain an ingredient, tetrahydrozoline, that is similar to a commonly used blood pressure-lowering medication called clonidine.
Tetrahydrozoline causes constriction of blood vessels when it is applied directly on the eye; this reduces eye redness. When used in high amounts or when ingested, tetrahydrozoline can also cause sleepiness, low blood pressure, and a dangerously slow heart rate.
Young children who consume small amounts of tetrahydrozoline as little as one-half of one teaspoon can develop sleepiness and difficulty breathing. Teenagers and adults who drink larger amounts may also experience heart rhythm abnormalities and breathing problems that can be life-threatening. Interestingly, despite its reputation as a gastrointestinal irritant, diarrhea is not a common side effect of tetrahydrozoline consumption.
Most cases of tetrahydrozoline exposure occur in adults, but more than one-fourth of all exposures occur in toddlers years of age. Because tetrahydrozoline ingestion can cause significant toxicity in young children, it is very important for parents and caregivers of young children to be aware of this potentially very dangerous poison.
