AK-Dilate

Generic name: Phenylephrine Ophthalmic

Usage of AK-Dilate

Phenylephrine is a decongestant that shrinks blood vessels.

AK-Dilate (for the eyes) is used to relieve eye redness, dryness, burning, and irritation caused by wind, sun, and other irritants.

Prescription-strength AK-Dilate 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.

AK-Dilate may also be used for purposes not listed in this medication guide.

How to use AK-Dilate

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 AK-Dilate.

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 AK-Dilate.

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.
