Naphazoline
About Naphazoline
Naphazoline is an ophthalmic (eye) solution used to relieve redness, puffiness, and minor irritation in the eyes. It is designed to soothe discomfort caused by common environmental triggers like dust, wind, swimming, or reading for long periods.
You typically use these eye drops up to four times a day, only when you need temporary relief from eye irritation. Because this is a liquid drop applied directly to the eye, it can be taken with or without food. Combining the use of these drops with simple lifestyle protective measures, such as wearing sunglasses outdoors, can help protect your eyes and maintain your results.
While using Naphazoline, you might experience mild, temporary stinging or slightly blurred vision immediately after applying the drops. These feelings usually pass quickly, but if you experience severe eye pain, changes in your vision, or redness that gets worse or lasts longer than 72 hours, stop using the drops and consult your doctor immediately.
Before you start using Naphazoline, tell your doctor if you have any pre-existing health conditions. Do not take this if you have narrow-angle glaucoma, as it can cause a dangerous increase in pressure inside your eye. It is also important to talk to your doctor or pharmacist if you have high blood pressure, heart problems, or diabetes.
This medicine may interact with certain other treatments, especially some types of antidepressants or blood pressure medications, which can cause sudden shifts in blood pressure. If you are pregnant, breastfeeding, or caring for an elderly individual, consult your doctor before using these drops to ensure they are safe for your specific situation.
Uses of Naphazoline
Medicinal Benefits
Naphazoline may provide the following benefits for temporary relief of minor eye redness and irritation:
- Reduces eye redness: Naphazoline narrows small blood vessels on the surface of the eye, making redness less noticeable.
- Provides temporary relief from irritation: It may help relieve minor eye discomfort linked with redness caused by environmental irritants.
- Helps improve eye comfort: By reducing redness and related irritation, Naphazoline can make the eyes feel more comfortable for a short time.
Directions for Use
• Follow your doctor's advise regarding the dosage and duration.
• Lie down and tilt your head backwards. Pull your lower eyelid gently with your index finger to form a pocket. Instil the number of drops as advised by the doctor into the pocket of the lower eyelid. Close your eyes for 1-2 minutes.
• Do not touch the container tip to the eye, eyelids, or surrounding areas as it may cause contamination.

Patients Concern
Disease/Condition Glossary
Ocular congestion: Ocular congestion is a symptom caused by inflammation of the conjunctiva, which is the thin and transparent membrane covering the eye's white area and the eyelids' inner part. Discharge of eye fluids, redness, itchiness or a gritty feeling in one or both eyes, tearing and sensitivity to light are the most common symptoms of Ocular congestion.
FAQs
Naphazoline is used to treat Ocular congestion, discomfort, and inflammation.
Naphazoline is a vasoconstrictor that reduces congestion at the administration site by activating alpha-adrenergic receptors in arterioles (blood vessels). Thus, it reduces the symptoms of ocular congestion, discomfort, and inflammation (redness and swelling in the eye).
Depending on the dose of the eye drops and the individual patient, the effects can last up to six hours. People with lighter eyes experience the effects of the drops for a longer period of time than those with darker eyes.
You are recommended to maintain a minimum 5-minute time gap between using Naphazoline and other eye drops. However, please consult a doctor before using other medicines with Naphazoline.
Naphazoline might cause blurred vision, which might last for several hours.
No, you should not use Naphazoline while your contact lenses are in. The preservatives in the eye drops can be absorbed by soft lenses, causing discolouration and eye irritation. Take your lenses out before applying the drops, and wait at least 15 minutes before putting them back in. Talk to your doctor if your eye redness continues.
Using Naphazoline for longer than recommended can cause a 'rebound' effect. This means your blood vessels become dependent on the drug, and when it wears off, your eyes will become even redder and more irritated. If your eye irritation is persistent, talk to your doctor.
Yes, in some cases, Naphazoline can cause temporary pupil dilation (widening of the black part of your eye). This can make your eyes temporarily more sensitive to bright light. If this effect persists or causes vision problems, stop using the drops and talk to your doctor.
Do not use Naphazoline if you have narrow-angle glaucoma, as it can dangerously increase eye pressure. If you have other types of glaucoma, you should consult your eye specialist first. Always talk to your doctor before starting any new eye drops.
A mild, brief stinging or burning sensation is a common reaction when you first apply the drops. This should go away within a few seconds. If the stinging is severe, causes pain, or does not stop, rinse your eyes with clean water, stop using the drops, and talk to your doctor.
No, Naphazoline is only meant to relieve minor irritation and environmental redness. It does not treat infections caused by bacteria, viruses, or fungi. If you have eye pain, thick discharge, or swelling, talk to your doctor immediately.
The safety of Naphazoline during pregnancy has not been fully established, as small amounts can be absorbed into the body. It should only be used if recommended by a healthcare provider. Talk to your doctor to understand the risks and benefits.
