Drinking eye drops can be dangerous; it may cause toxicity, leading to symptoms like nausea, dizziness, or more severe health issues depending on the ingredients.
Accidental or intentional ingestion of eye drops can lead to severe poisoning, with symptoms ranging from nausea to life-threatening complications. Anti-redness drops containing tetrahydrozoline are particularly dangerous when swallowed, even in small amounts.
Why Eye Drops Are Dangerous When Ingested
Most over-the-counter eye drops contain vasoconstrictors like tetrahydrozoline, which work by shrinking blood vessels in the eyes. When swallowed, these chemicals affect the entire body’s vascular system and nervous system.

These brands contain tetrahydrozoline:
- Visine Original
- Murine Plus
- Clear Eyes Redness Relief
Symptoms of Eye Drop Poisoning
Symptoms vary by age and amount consumed:
In Children (½ teaspoon or less)
- Extreme drowsiness

In Adults (1 teaspoon or more)
- Dangerously low blood pressure
- Abnormal heart rhythms

- Coma
According to America’s Poison Centers, 771 tetrahydrozoline exposures were reported in 2025, with 40% involving children under 5.
Emergency Response for Eye Drop Ingestion

Fatal Cases and Criminal Use
In rare cases, eye drops have been used as poison:
- A North Carolina woman was arrested for spiking her fiancé’s drink with Visine
- A South Carolina woman received 25 years for killing her husband with eye drop-laced food
These cases highlight why products like non-toxic juicers are becoming increasingly popular for health-conscious consumers.
The Mount Sinai Health System notes that survival past 24 hours usually indicates recovery, but organ damage may occur in severe cases.
