Can drinking 5 drops of visine kill you?

Drinking 5 drops of Visine, which contains the active ingredient tetrahydrozoline, can be harmful but is unlikely to be lethal for most people. However, ingesting even small amounts can lead to serious side effects, including respiratory distress, decreased heart rate, and other toxic effects, particularly in children or individuals with certain health conditions. If ingestion occurs, it’s important to seek medical attention immediately. Always use medications as directed and keep them out of reach of children.
