Naphazoline (drops) (Naphazoline) — Uses, Dosage, Side Effects & Safety

Drug class: Ophthalmic/Vasoconstrictor (Alpha-adrenergic agonist)

Overview

Naphazoline (drops) is a medication used to relieve redness, irritation, and minor discomfort in the eyes caused by allergies, dust, smoke, or other irritants. It is also sometimes used in nasal preparations to relieve nasal congestion. Naphazoline works by narrowing the blood vessels in the eye (or nasal passages), which reduces swelling and redness. This effect is due to its action as an alpha-adrenergic agonist, causing vasoconstriction. Key points for patients: Use only as directed, avoid prolonged use (more than a few days) to prevent rebound redness, and do not use if you have certain eye conditions like glaucoma unless advised by your doctor.
