Xalatan (Generic)

Latanoprost is used to treat high pressure inside the eye due to glaucoma (open angle type) or other eye diseases (e.g., ocular hypertension). It is similar to a natural chemical in the body (prostaglandin) and works by regulating the flow of fluid within the eye which results in lower pressure. Lowering high pressure inside the eye helps to prevent blindness.

Apply this medication in the affected eye(s) usually once daily in the evening, or as directed by your doctor. Do not use this medication more frequently than prescribed; using more can decrease effectiveness.

To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface.

If you are wearing contact lenses, remove them before using this medication. Wait at least 15 minutes before replacing your contact lenses.

Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop into the pouch. Look downward, gently close your eyes, and place one finger at the corner of your eye (near the nose). Apply gentle pressure for 1 to 2 minutes before opening your eyes. This will prevent the medication from draining out. Try not to blink or rub your eye. Repeat these steps if your dose is for more than one drop. If directed to use this medication in both eyes, repeat these steps for your other eye. Do not rinse the dropper. Replace the dropper cap after each use.

Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day. Keep using latanoprost even if you feel well. Most people with glaucoma or high pressure in the eye do not feel sick.

If you are using another kind of eye medication (e.g., drops or ointments), wait at least 5 minutes before applying other products. Use eye drops before eye ointments to allow the eye drops to enter the eye.

Blurred vision, burning/stinging/itching/redness of the eye, feeling as if something is in the eye, changes in eyelash number/color/length/thickness, eyelid changes/skin darkening, dry eye, lid crusting/discomfort, or increased sensitivity to light may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

This medication may slowly (over months to years) cause brown discoloration of the colored portion of the eye (iris). If you are using latanoprost in only one eye, only that iris may change color. This color change may be permanent but the long-term effects are uncertain. Notify your doctor if this occurs and schedule regular eye exams to monitor it.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
