Key takeaways
Travoprost (Travatan Z) and betaxolol (Betoptic-S) are both eye drop medications used to lower high pressure in the eye caused by open-angle glaucoma or ocular hypertension. However, they belong to different medication classes. Travoprost is a prostaglandin, which works by helping fluid drain from the eye, while betaxolol is a beta blocker that reduces the amount of fluid produced in the eye. Travoprost is typically applied once daily in the evening, whereas betaxolol is used twice a day. Both medications are available as a lower-cost generic. Common side effects of travoprost include eye redness and discomfort, while betaxolol may cause temporary eye discomfort and watery eyes. Betaxolol is not recommended for people with certain heart or lung conditions, as it can affect heart rate and breathing. In contrast, travoprost can cause changes in eyelash growth and eye color, which are not harmful but may be permanent.
