Key takeaways
Latanoprost (Xalatan) and timolol (Timoptic) are both eye drop medications used to treat high pressure in the eye, such as in cases of open-angle glaucoma or ocular hypertension. While they share this purpose, they belong to different medication classes. Latanoprost is a prostaglandin that works by helping fluid drain from the eye, and it's typically used once daily in the evening. Timolol, on the other hand, is a beta blocker that reduces the amount of fluid in the eye and is usually applied once or twice a day. Latanoprost is available in both brand-name and generic forms, while timolol is only available as a generic since the brand name Timoptic has been discontinued. Common side effects of latanoprost include eye stinging, burning, and changes in eye color, whereas timolol may cause burning, stinging, and potentially affect heart rate or breathing. Latanoprost requires refrigeration before opening, while timolol is stored at room temperature. Additionally, timolol should be used with caution if you have heart or lung conditions.
