Having trouble finding Cosopt eye drops at your pharmacy? Learn why Cosopt is hard to find in 2026, what's causing supply issues, and what you can do.
You rely on Cosopt to manage your glaucoma or ocular hypertension. But lately, every time you try to pick up your prescription, the pharmacist tells you it's unavailable. You're left wondering: why is Cosopt so hard to find?
The truth is, supply disruptions for Cosopt and its generic equivalent, Dorzolamide/Timolol, have been an ongoing challenge. In this article, we'll explain what Cosopt is, why it can be difficult to find, and — most importantly — what you can do about it.
Cosopt is a prescription eye drop that combines two active ingredients: Dorzolamide (a carbonic anhydrase inhibitor) and Timolol (a beta-blocker). Together, these medications work to lower the pressure inside your eye by reducing the amount of fluid (aqueous humor) your eye produces.
Cosopt is FDA-approved for treating open-angle glaucoma and ocular hypertension in patients who need more than one medication to control their eye pressure. It comes as a standard ophthalmic solution (10 mL bottle) and a preservative-free version called Cosopt PF.

There are several reasons why you might be having trouble filling your Cosopt prescription right now.
The generic version of Cosopt — Dorzolamide/Timolol — used to be made by multiple companies. However, one of the largest generic manufacturers, Akorn, went bankrupt in 2023. This reduced the number of suppliers making the product, which means any disruption at a remaining manufacturer can ripple across the entire supply chain.
Cosopt and its generics have a history of manufacturing delays. Bausch Health and other producers have experienced production setbacks. Ophthalmic solutions require strict sterile manufacturing conditions, and any quality control issue can halt production for weeks or months.
Even when Cosopt is being manufactured, it doesn't always reach every pharmacy evenly. Large chain pharmacies may receive priority shipments, while smaller or independent pharmacies can face longer waits. If your pharmacy uses a specific wholesaler that's running low, you'll feel the pinch.
Glaucoma affects over 3 million Americans, and that number is growing as the population ages. As more patients need intraocular pressure-lowering medications, demand for affordable options like generic Dorzolamide/Timolol increases. When demand outpaces supply, shortages happen.
If your pharmacy doesn't have Cosopt or its generic in stock, don't panic. Here are some practical steps:
The fastest way to find Cosopt in stock near you is to use Medfinder. It searches pharmacy inventories in real time so you can see which locations have your medication available right now.
Independent pharmacies often have access to different wholesalers than chain stores. They may have Dorzolamide/Timolol in stock when the big chains don't. It's worth making a few calls.
If the standard Cosopt solution is unavailable, ask your doctor about Cosopt PF (preservative-free). It's the same medication in single-use vials. Sometimes one formulation is in stock when the other isn't.
If you simply cannot find Cosopt, your eye doctor may be able to switch you to an alternative combination drop. Options include Combigan (Brimonidine/Timolol) or Simbrinza (Brinzolamide/Brimonidine). You can also use Dorzolamide and Timolol as separate drops. Learn more in our article on alternatives to Cosopt.
Glaucoma damage is permanent and painless — you won't feel the pressure building up. Missing doses of your eye drops can allow your eye pressure to rise, increasing the risk of vision loss. If you're running low, act quickly to find a refill or get a temporary alternative from your doctor.
Cosopt supply issues can be frustrating, especially when your vision depends on consistent treatment. The good news is that generic Dorzolamide/Timolol is still being manufactured by several companies, and availability is generally improving. By staying proactive — checking Medfinder, exploring different pharmacies, and keeping your doctor informed — you can stay on top of your treatment.
