Summary
Naphazoline is used to relieve eye redness and irritation, which are symptoms caused by minor irritants like dust or smoke. It provides temporary relief and is not meant for long-term use or serious eye conditions.
Naphazoline works by constricting blood vessels in the eyes, which reduces redness and irritation. This action is similar to turning down the flow of water in a hose to reduce pressure.
Naphazoline is usually administered as eye drops. The typical dose for adults is one or two drops in the affected eye(s) every three to four hours as needed. Always follow your doctor's instructions.
Common side effects of naphazoline include temporary stinging or burning in the eyes. These effects are usually mild and go away on their own. Serious side effects are rare but can include eye pain or changes in vision.
Naphazoline should not be used if you have narrow-angle glaucoma, which is a condition that increases eye pressure. Overuse can lead to increased redness or irritation. Always follow prescribed instructions to avoid adverse effects.
