Naphazoline: functions, dosage, side effects, how to use

What Drug Naphazoline?

What is naphazoline for?

Naphazoline is a decongestant used to relieve redness, swelling, and itching / watery eyes from a cold, allergies, or eye irritation (from smoke, swimming, or wearing contact lenses). These drugs are known as sympathomimetics (alpha receptor agonists) which act on the eye to reduce congestion.

Some brands of naphazoline eye drops also contain other ingredients. Lubricants (such as glycerin, hypromellose, or polyethylene glycol 300) help protect the eye from irritation. Zinc sulfate, is a substance that can help reduce redness and irritation.

How is naphazoline used?

Before dropping it on your eyes, wash your hands first. To avoid contamination, do not touch the tip of the dropper or let it touch your eye or other surface.

Remove your contact lenses before placing the drops. Wait at least 10 minutes after using the medicine before putting on contact lenses.

Before using it, check the product packaging. Do not use it if the liquid has turned cloudy. Use and aim at the sore eye.

Tilt your head, look up, and pull up the lower lids of your eyes. Hold the dropper over your eye and drop it into the eye bag. Close your eyes slowly for 1 to 2 minutes. Place one finger on the corner of the eye close to your nose and press gently on the area. This can prevent the drug from flowing out. Try not to blink or rub your eyes. Repeat this step if you have more than one drop and if you need a drop in the other eye.

Do not rinse the used dropper. Change the pipette after use.

If you are using other eye medications (such as drops or ointments), wait at least 5 minutes before using the other medication. Use eye drops before applying eye ointment to let the eye drops into the eye.

Using this drug excessively can cause red eyes (blocky hyperemia). Tell your doctor if this happens or if your condition continues or gets worse after 48 hours. If you experience eye pain / changes in your vision or think you have a serious health problem, seek immediate medical help.
