Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Latanoprost (Xalatan) and timolol (Betimol) are both eye drop medications used to lower eye pressure in conditions like ocular hypertension and open-angle glaucoma, but they belong to different drug classes and work differently. Latanoprost is a prostaglandin that helps fluid drain from the eye, while timolol is a beta blocker that reduces the amount of fluid produced in the eye. Latanoprost is typically used once daily in the evening, whereas timolol is usually taken once or twice a day. Latanoprost can cause changes in eye color and eyelash growth, while timolol can lead to systemic effects like lower blood pressure and heart rate. Timolol should be avoided if you have asthma or certain heart conditions, but latanoprost does not have these specific contraindications. Both medications are available in generic forms, making them more affordable options.
