Latanoprost: What It Is, How It Works, and What You Need to Know
When your eye pressure stays too high, it can quietly damage your vision over time. That’s where latanoprost, a prostaglandin analog used to reduce intraocular pressure in glaucoma and ocular hypertension. Also known as Xalatan, it’s one of the most prescribed eye drops for keeping pressure under control without daily pills or surgery. Unlike older treatments that make your eye produce less fluid, latanoprost works by helping your eye drain fluid more efficiently — a simpler, more natural fix.
It’s not just a drop. It’s part of a bigger picture. People using latanoprost often combine it with other treatments like beta-blockers or carbonic anhydrase inhibitors when pressure doesn’t drop enough on its own. It’s also commonly used when patients can’t tolerate oral meds or need something with fewer systemic side effects. The key advantage? One drop at night. That’s it. No multiple doses. No complex routines. For many, that’s the difference between sticking with treatment and giving up.
But it’s not perfect. Some users notice their eyelashes growing longer, darker, or thicker — a side effect that surprises people. Others see a gradual change in iris color, especially if they have mixed brown-green eyes. These changes are usually permanent, but they’re not dangerous. What matters more is whether your pressure is going down. If your doctor switches you to latanoprost, it’s because the goal is simple: protect your sight before you even notice something’s wrong.
It’s not just for glaucoma. Doctors also use it for ocular hypertension — when pressure is high but there’s no nerve damage yet. Catching it early with latanoprost can stop damage before it starts. And unlike some older eye drops that cause stinging or redness all day, latanoprost is usually well-tolerated. Most people barely feel it after the first few days.
What you’ll find in the posts below isn’t just a list of articles. It’s a collection of real-world stories and comparisons from people managing chronic eye conditions. You’ll see how latanoprost stacks up against other pressure-lowering drops, what happens when it stops working, and how lifestyle choices like sleep position or caffeine intake can quietly affect its results. Some posts dig into the science. Others give you the blunt truth from patients who’ve been there. No fluff. No marketing. Just what works — and what doesn’t.
The Science Behind Latanoprost: How It Lowers Eye Pressure
Latanoprost lowers eye pressure by improving fluid drainage in the eye, making it a first-line treatment for glaucoma. It works overnight, reduces pressure by up to 33%, and is safe for long-term use with minimal side effects.
