 Glaucoma Medicines

Glaucoma is a group of eye diseases that can cause vision loss and blindness by damaging the nerve in the back of your eye called the optic nerve.

The most common treatment for glaucoma is prescription eye drops. They work by lowering the pressure in your eye and preventing damage to your optic nerve. These eye drops won’t cure glaucoma or reverse vision loss, but they can keep glaucoma from getting worse. 


If your doctor prescribes eye drops for glaucoma, you’ll need to use them every day. Depending on the type of medicine, you may need to use them once, twice, or up to 4 times a day.  

What types of eye drops can help glaucoma?

There are many medicines available to treat glaucoma. Before you start taking glaucoma medicines, tell your doctor about other medicines, supplements, or vitamins you take. Eye drops for glaucoma may affect how those other medicines work. 


Some types of eye drops work by helping fluid drain from your eye, which lowers eye pressure. Examples include: 


Prostaglandins, like Xalatan (latanoprost), Travatan Z (travoprost), Zioptan (tafluprost), and Lumigan (bimatoprost) 

Rho kinase inhibitor, like Rhopressa (netarsudil) 

Nitric oxides, like Vyzulta (latanoprostene bunod) 

Miotic or cholinergic agents, like Isopto Carpine (pilocarpine) 

Other types of eye drops work by lowering the amount of fluid your eye makes. Examples include: 


Alpha-adrenergic agonists, like Iopidine (apraclonidine) and Alphagan P or Qoliana (brimonidine) 

Beta blockers, like Betoptic (betaxolol) and Betimol, Istalol, or Timoptic (timolol) 

Carbonic anhydrase inhibitors, like Trusopt (dorzolamide) and Azopt (brinzolamide) 


What are the side effects?

Most people don’t have problems with glaucoma medicines. But there’s a small chance that you could develop: 


Stinging, itching, burning, and redness in your eye 

Blurry vision 

Changes in your eye color or the skin around your eye 

Headaches 

Dry mouth 

Changes in your energy level, heartbeat, or breathing 

The specific side effects depend on which medicine you’re taking. If you notice any side effects, talk to your doctor. You may be able to take a different dose (amount) or a different medicine. 

How long will I need to use glaucoma eye drops?

As long as the medicine is working, your doctor will probably want you to keep using it every day.


If eye drops don’t lower the pressure in your eye enough, your doctor may recommend prescription pills as well — but this is uncommon. 


Your doctor may also suggest other treatment options, like laser treatment or surgery.

  What Are the Effects of Climate Change? Climate change is our planet’s greatest existential threat. If we don’t limit greenhouse gas emissions from the burning of fossil fuels, the consequences of rising global temperatures include massive crop and fishery collapse, the disappearance of hundreds of thousands of species, and entire communities becoming uninhabitable. While these outcomes may still be avoidable, climate change is already causing suffering and death. From raging wildfires and supercharged storms, its compounding effects can be felt today, outside our own windows. Understanding these impacts can help us prepare for what’s here, what’s avoidable, and what’s yet to come, and to better prepare and protect all communities. Even though everyone is or will be affected by climate change, those living in the world’s poorest countries—which have contributed least to the problem—are the most climate-vulnerable. They have the fewest financial resources to respond to crises or adapt
