Latanoprost: What It Is, How It Works, and What You Need to Know

When your eye pressure stays too high, it can silently damage your vision—and Latanoprost, a prostaglandin analog eye drop used to reduce intraocular pressure in glaucoma and ocular hypertension. Also known as Xalatan, it’s one of the most prescribed treatments for keeping pressure under control without surgery. Unlike pills or injections, Latanoprost works right where it’s needed: in your eyes. You use it once a day, usually at night, and it gently opens drainage channels to let fluid escape—lowering pressure before it harms your optic nerve.

This isn’t just about preventing blindness. For many, Latanoprost means keeping their independence. People who drive, read, or work on computers rely on stable vision, and this medication helps them hold onto it. It’s not a cure, but it’s a tool that works for years if used consistently. What’s more, it’s often the first choice because it’s effective, has fewer systemic side effects than older drugs, and doesn’t require multiple daily doses. Doctors know this. Patients know this. And the data backs it up—studies show it lowers eye pressure by 25% to 33% on average.

But Latanoprost doesn’t work the same for everyone. Some notice darker lashes or changes in iris color over time—minor, but noticeable. Others get redness or stinging at first, which usually fades. It’s not for people with certain eye infections or inflammation, and it shouldn’t be used with other prostaglandin drops. That’s why it’s always paired with a doctor’s guidance. You can’t just buy it off the shelf. But once you’re on it, managing your routine becomes part of daily life—like brushing your teeth.

Related treatments like timolol, brimonidine, or travoprost are alternatives, but Latanoprost stands out because of its once-daily dosing and strong track record. It’s the baseline many others are measured against. If you’ve been told you have glaucoma or high eye pressure, chances are you’ve heard of it. And if you’re wondering whether it’s right for you, or how it compares to newer options, you’re not alone.

Below, you’ll find real patient stories, comparisons with other eye pressure meds, and practical tips on using Latanoprost correctly—so you get the most out of it without surprises. No fluff. Just what matters.
