What Is Xalatan Used For?

If your ophthalmologist determines that you are at risk for developing glaucoma, she may prescribe a prescription medication called Xalatan to hinder its progression. Allaboutvision.com reports that glaucoma is one of the leading causes of blindness in the United States (second only to diabetes), and millions of Americans have the disease.

What is Xalatan?

• Rxlist.com describes Xalatan as latanoprost ophthalmic solution. Latanoprost (pronounced la-TA-noe-prost), is the active ingredient in Xalatan and was approved by the Food and Drug Administration in 1996. The sterile solution contains sodium chloride as an inactive ingredient, and benzalkonium chloride is added to the latanoprost mixture for purposes of preservation.

Glaucoma and Fluid Pressure

• The optic nerve is the lifeline that attaches the retina to the brain. When the optic nerve is damaged, vision loss can occur. Glaucoma jeopardizes the health of the optic nerve by raising the fluid pressure in the eye. According to the National Eye Institute, this form of glaucoma is referred to as low-tension glaucoma and is prevalent in people who are age 60 and over, and those with a family history of glaucoma.

How Xalatan Helps

• The latanoprost contained in the Xalatatan prescription works to reduce the overall fluid pressure in the eye. Glaucoma tends to cause closing of the drainage channels in the eye. Xalatan helps to reopen those sealed chambers, increasing fluid excretions and lowering fluid pressure.

Eye Color Changes

• The University of Maryland reports that the use of latanoprost may alter the color of the eye. Changes in the color of the iris have been noted in patients using latanoprost, with most of the color changes affecting those with iris colors that naturally have brown undertones. In all cases, the brown color is intensified.

How Often is Xalatan Used?

• According to Xalatan.com, the prescription should be used only once a day, preferably in the evening. One drop should be applied topically by pulling down on the lower lid of your eye. Never use more than one drop daily. Even if you miss a day, don't double up. To prevent eye infections, wash your hands thoroughly before applying the Xalatan drops.

Who Should Not Use Xalatan

• As with any drug, proper precautions should be taken. According to healthline.com, if you are pregnant, Xalatan may cause damage to your unborn fetus. Therefore, it's important to discuss alternatives with a doctor. Also, if you're nursing, Xalatan can pass through your breast milk to your baby.
