Neofrin
Generic name: Phenylephrine Ophthalmic
Usage of Neofrin
Phenylephrine is a decongestant that shrinks blood vessels.
Neofrin (for the eyes) is used to relieve eye redness, dryness, burning, and irritation caused by wind, sun, and other irritants.
Prescription-strength Neofrin is used to constrict blood vessels in the eye and to dilate (make bigger) the pupil for conditions such as glaucoma, before surgery, and before eye examinations.
Neofrin may also be used for purposes not listed in this medication guide.

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Although the risk of serious side effects is low when Neofrin is used in the eyes, side effects can occur if the medicine is absorbed into your bloodstream. Stop using this medicine and call your doctor at once if you have:

Before taking Neofrin
You should not use Neofrin if you are allergic to it, or if you have narrow-angle glaucoma.
Do not use Neofrin without a doctor's advice if you have:
Any of the conditions above could cause your eyes to absorb Neofrin into your body, which could lead to dangerous effects on the heart.

How to use Neofrin
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.
Wash your hands before using the eye drops.
To apply the eye drops:
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.
Your blood pressure may need to be checked while you are using Neofrin.
Do not use this medicine for longer than 3 days. Call your doctor if your symptoms do not improve, or if they get worse while using Neofrin.
Long-term use of phenylephrine ophthalmic may damage the blood vessels (veins and arteries) in the eyes.
Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.
