Which latanoprost brand name is preservative-free?

• A. Lyuzeh
• B. Xalatan
• C. Xelpros
• D. Travatan Z

Answer: (A)

Preservative-free formulations aim to minimize exposure of the eye to preservation chemicals that can cause irritation with long-term use. The latanoprost brand that is preservative-free comes in single-use vials with no preservative in the solution, so the drop you put in the eye contains no preservative agent. This makes it a good option for patients with sensitive eyes or those who have had intolerance to preservatives, while still delivering the same eye-pressure–lowering effect. In contrast, many other latanoprost brands include a preservative in their solution, which can be an irritant for some people; always check the packaging to confirm whether a product is preservative-free.
