Key takeaways
Latanoprost (Xalatan) and travoprost (Travatan Z) are both prostaglandin eye drops used to lower eye pressure in conditions like glaucoma and ocular hypertension. While both medications are applied once daily in the evening and work by helping fluid drain from the eye, there are some differences between them. Both medications are available in a generic form. Latanoprost needs to be refrigerated until opened, but travoprost can be stored at room temperature. Both medications can cause temporary stinging, redness, and eye inflammation. They can also change the color of your eyes and make your eyelashes grow longer and thicker. However, latanoprost has a specific risk of triggering herpes infections in the eye, which isn’t the case for travoprost.
