Xalatan is classified as an ophthalmic glaucoma agent and lowers pressure inside the eye by increasing the amount of fluid that drains from the eye.

Xalatan eye drops are used to treat certain types of glaucoma and other causes of high pressure inside the eye.

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

Do not use Xalatan while wearing contact lenses. This medication may contain a preservative that can discolor soft contact lenses. Wait at least 15 minutes after using Xalatan before putting your contact lenses in.

Xalatan 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.

Do not allow the tip of the dropper to touch any surface, including your eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye.

After using Xalatan, wait at least 5 minutes before using any other eye drops that your doctor has prescribed.

The usual dose of Xalatan is 1 drop into the affected eye every evening. Follow your doctor's dosing instructions very carefully.

Follow all directions on your prescription label. Do not use Xalatan in larger or smaller amounts or for longer than recommended.

Do not use Xalatan while wearing soft contact lenses. A preservative in this medicine could permanently stain the lenses. Wait at least 15 minutes before inserting your contact lenses.

Wash your hands before using the eye drops.

To apply the Xalatan 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 about 1 minute, to keep the liquid from draining into your tear duct.

• Wait at least 5 minutes before using any other 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 and 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.

Tell your doctor right away if you have an eye injury or eye infection, or if you plan to have eye surgery.

Store an unopened bottle of Xalatan eye drops in a refrigerator. Do not freeze.

After your first use, store the eye drops at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use. Throw away the medicine after 6 weeks have passed since you first opened the bottle.
