Naphcon-A is an over the counter medication used to treat eye itching and redness due to allergies in adults and children over 6 years of age.

Naphcon A contains 2 ingredients: naphazoline and pheniramine. Naphazoline belongs to a group of drugs called redness relievers. Pheniramine belongs to a group of drugs called antihistamines. Together these work by constricting the blood vessels in the eye and blocking the substances that cause allergies.

This medication comes in eye drop solution and is used up to four times a day.

Common side effects of Naphcon-A include stinging, redness, and blurred vision.

Put 1 or 2 drops in the affected eye(s) up to 4 times every day.

Naphazoline is a vasoconstrictor. It works by narrowing swollen blood vessels in the eyes to reduce eye redness.

Pheniramine is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of itchy or watery eyes.

Naphazoline and pheniramine ophthalmic (for the eyes) is for temporary relief of minor eye redness or itching caused by ragweed, pollen, grass, or animal dander and hair.

Naphazoline and pheniramine ophthalmic may also be used for purposes not listed in this medication guide.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Using the medicine too long or too often may worsen your symptoms and cause damage to blood vessels in your eyes.

Wash your hands before using the eye drops.

To apply the eye drops:

• Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye with the tip down. Look up and away from the dropper and squeeze out a drop.

• Close your eye and gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.

• Use only the number of drops recommended.

Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.

Do not use the eye drops if the liquid has changed colors or has particles in it. Call your pharmacist for new medicine.

Stop using this medicine and call your doctor if your symptoms do not improve after 3 days of treatment.

Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.

Throw away the eye drops after the expiration date on the medicine label has passed.
