Tetrahydrozoline

Tetrahydrozoline is a topical alpha-adrenergic agonist, commonly used as an over-the-counter eye drop medication. Its primary function is to constrict blood vessels in the eye, which helps reduce redness and swelling associated with eye irritation or inflammation.
Tetrahydrozoline is typically prescribed for the short-term relief of redness and swelling of the eye caused by minor conditions such as allergies, eye strain, or environmental irritants. It is not intended for long-term use, as it may cause rebound redness and other side effects.
When using tetrahydrozoline eye drops, follow the instructions provided by your healthcare professional or as directed on the product label. This medication should not be applied more frequently than four times a day, and it is important to avoid touching the tip of the dropper to the eye or any surrounding surfaces to prevent contamination and potential infection.
