What is Visine-A?
Pheniramine is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of itchy or watery eyes.
Visine-A (for the eyes) is for temporary relief of minor eye redness or itching caused by ragweed, pollen, grass, or animal dander and hair.
Visine-A 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.
Before taking this medicine
You should not use this medicine if you are allergic to naphazoline or pheniramine.

It is not known whether Visine-A will harm an unborn baby. Do not use this medicine without a doctor's advice if you are pregnant.

How should I use Visine-A?
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.
What happens if I miss a dose?
Since this medicine is used when needed, you may not be on a dosing schedule. If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

An overdose of Visine-A is not expected to be dangerous. Seek emergency medical attention or call the Poison Help line at 1-800-222-1222 if anyone has accidentally swallowed the medication.
Keep this medicine out of the reach of children. Certain eye medications can cause serious medical problems in a young child who accidentally sucks on or swallows medicine from the eye dropper.
