Key takeaways
Lumigan (bimatoprost) and Travoprost (Travatan Z) are both prostaglandin eye drops used to lower high pressure in the eye, such as in cases of glaucoma or high eye pressure. Lumigan is available in two strengths (0.01% and 0.03%), with the 0.03% strength only available as a generic. Travoprost is available as a lower-cost generic. Both medications are typically applied once daily in the evening. Lumigan starts to work within 4 hours and reaches full effect in 8 to 12 hours, whereas travoprost begins to lower eye pressure in about 2 hours and reaches maximum effect in 12 hours. Common side effects for both include eye redness and changes in eye color, but Lumigan is more likely to cause eyelash growth. Both medications can cause permanent darkening of the eye color and require you to remove contact lenses before use. However, travoprost can be stored at room temperature or in a cool place, while Lumigan should be kept at room temperature.
