Among the variety of eye disorders affecting dogs, glaucoma is one of the most devastating. Indeed, this eye condition left untreated, could potentially lead to significant pain and ultimately, even permanent vision loss. While surgery is the only way to treat glaucoma, Xalatan is a topical product that can be used in order to alleviate the symptoms of glaucoma and delay its onset.

Identification
-
Xalatan, also known by its generic name Latanoprost, is a topical medication belonging to a group of drugs known as prostaglandin F2-alpha agonists. This medication is available as a 0.005 percent solution in a 2.5 ml bottle that is typically obtained by prescription from a veterinarian or an eye specialist for animals. While this drug is not approved by the FDA, it can be legally prescribed by veterinarians as an extra label drug, according to Pet Place veterinarians.
Function
-
Glaucoma takes place when too much pressure builds up in the dog's eye. This pressure typically forms when the eye's drainage system becomes clogged and the eye keeps producing fluid. Overwhelmed by the increased pressure, the eye stretches and enlarges in addition to losing vision, according to Animal Eye Care LLC, a referral practice for eye diseases in companion animals based in Bellingham, Washington. Xalatan mainly works by reducing the pressure within the eye, while increasing the amount of fluids that flow out of the eye.
Dosage
-
Instructions should be followed carefully when using Xalatan in dogs Xalatan should be given only under the instructions and guidance of a licensed veterinarian or veterinary opthamologist. Generally, the product is instilled into the eye once daily in the evening. Evening applications are preferred because there are less fluctuations in the pressure of the eye and lower chances of developing a pinpoint pupil. Twice daily administrations however are sometimes prescribed for poorly controlled glaucoma or for short-term use, generally following laser surgery or cryotherapy.
Warning
-
As with any medication, Xalatan eye drops may cause side effects. The most commonly reported are excessive constriction of the pupil, stinging upon application, red eyes, tearing and a worsening of eye inflammation. Xalatan should not be used in dogs known to be allergic or sensitive to such medication.
Interaction with other medications should be considered even though it is generally used safely with several other eye medications. In order to be effective, unopened bottles of Xalatan should be stored in a refrigerator, however, once opened they can be stored at room temperature for a maximum of six weeks, according to Pet Place veterinarians.
Time Frame
-
The length of use mainly depends on the severity of the condition being treated, the dog's response and the development of any side effects. Glaucoma medications should be given exactly as prescribed, and most importantly on a consistent and reliable time schedule. Should the dog's eye appear to be doing better, it is important to continue using Xalatan, unless specifically instructed by the veterinarian.
