Key takeaways
Travoprost (Travatan Z) and Alphagan P (brimonidine) are both prescription eye drops used to lower eye pressure and treat glaucoma, but they belong to different drug classes and have distinct usage patterns. Travoprost is a prostaglandin that helps fluid drain from the eye and is typically applied once a day in the evening. In contrast, brimonidine is an alpha-2 agonist that reduces fluid production in the eye and needs to be applied three times a day. Travoprost can cause side effects like eye redness and changes in eye color, while brimonidine may lead to dry mouth, headaches, and drowsiness. Additionally, travoprost can make your eyelashes grow longer and thicker, a side effect not seen with brimonidine. Both medications require you to remove contact lenses before application and are available as lower-cost generics.
