What is Altafrin (phenylephrine ophthalmic)?
Phenylephrine is a decongestant that shrinks blood vessels.
Phenylephrine ophthalmic (for the eyes) is used to relieve eye redness, dryness, burning, and irritation caused by wind, sun, and other irritants.
Prescription-strength phenylephrine ophthalmic 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.
Phenylephrine ophthalmic may also be used for purposes not listed in this medication guide.
How should I use Altafrin (phenylephrine ophthalmic)?
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:
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 eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for 2 to 3 minutes, to keep the liquid from draining into your tear duct.
Use only the number of drops your doctor has prescribed, or as recommended on the medicine label. If you use more than one drop, wait about 5 minutes between drops.
Wait at least 10 minutes before using any other eye drops your doctor has prescribed.
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 phenylephrine ophthalmic.
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 phenylephrine ophthalmic.
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.
Altafrin (phenylephrine ophthalmic) side effects
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 phenylephrine ophthalmic is used in the eyes, side effects can occur if the medicine is absorbed into your bloodstream. Stop using phenylephrine ophthalmic and call your doctor at once if you have:
fast or irregular heart rate;
pale skin, light-headed feeling;
severe headache, buzzing in your ears, anxiety, shortness of breath; or

Less serious side effects may be more likely, and you may have none at all.
