Zioptan reduces pressure in the eye by increasing the amount of fluid that drains from the eye.

Zioptan eye drops are used to treat open-angle glaucoma or other causes of increased pressure inside the eye.

Zioptan may also be used for purposes not listed in this medication guide.

Zioptan may cause a gradual change in the color of your eyes or eyelids and lashes. Color changes may be permanent even after your treatment ends, and may occur only in the eye being treated.

When using Zioptan tell your doctor right away if you have any eye injury or infection, sudden vision changes, or if you need to have any type of surgery, especially eye surgery.

Call your doctor at once if you have eye pain or redness, itchy or watery eyes, or increased sensitivity to light.

Use Zioptan eue drops exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Using more Zioptan than prescribed will not improve your condition, and may make this medicine less effective.

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 Zioptan 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 about 1 minute, to keep the liquid from draining into your tear duct.

• Wait at least 5 minutes before using any other eye drops your doctor has prescribed.

Each single-use bottle of Zioptan is for one use only (in one or both eyes at one time). Throw the eye drop bottle away after one use, even if there is still some medicine left in it after using the eye drops.

Tell your doctor right away if you have any eye injury or infection, sudden vision changes, or if you need to have any type of surgery, especially eye surgery.

Store unopened cartons of Zioptan or the foil pouches in the refrigerator, do not freeze.

After opening the foil pouch, store this medicine at room temperature away from moisture and heat. Once the pouch is opened, you must use the Zioptan eye drops within 28 days.

You should not use Zioptan if you are allergic to tafluprost.

Zioptan may cause a gradual change in the color of your eyes or eyelids and lashes, as well as increased growth or thickness of your eyelashes. These color changes, usually an increase in brown pigment, occur slowly and you may not notice them for months or years. Color changes may be permanent even after your treatment ends, and may occur only in the eye being treated. This could result in a cosmetic difference in eye or eyelash color from one eye to the other.

To make sure Zioptan is safe for you, tell your doctor if you have:

• uveitis;

• any swelling or infection in or around your eye; or

• a torn or missing natural lens from inside your eye.
