Can't fill your Iyuzeh prescription? Here are the best alternatives for preservative-free glaucoma treatment, including Travatan Z and generic Latanoprost.
If you've been prescribed Iyuzeh for glaucoma or ocular hypertension and can't find it at your pharmacy, you're probably wondering what your other options are. The good news is that several effective alternatives exist — though each has its own trade-offs.
In this guide, we'll explain what Iyuzeh is, how it works, and walk you through the best alternatives to discuss with your eye doctor.
Iyuzeh is the brand name for preservative-free Latanoprost ophthalmic solution 0.005%. Made by Thea Pharma Inc., it was FDA-approved in November 2022 and is the first and only preservative-free Latanoprost available in the United States.
It's prescribed for adults with open-angle glaucoma or ocular hypertension — conditions where elevated pressure inside the eye can damage the optic nerve and lead to vision loss if left untreated.
Iyuzeh comes in single-dose containers, meaning you open a fresh vial each time you use it and throw it away after. This eliminates the need for preservatives like benzalkonium chloride (BAK), which is found in most other glaucoma eye drops and can cause eye surface irritation with long-term use.
Iyuzeh belongs to a class of drugs called prostaglandin analogs. These medications lower intraocular pressure (IOP) by increasing the outflow of aqueous humor — the clear fluid inside your eye — through the uveoscleral pathway. You apply one drop in the affected eye(s) once daily in the evening, and the pressure-lowering effect starts within 3–4 hours and peaks at 8–12 hours.

If Iyuzeh is unavailable or unaffordable, here are the most common alternatives your doctor may recommend. All of these are prostaglandin analogs that work in a similar way to lower eye pressure.
Generic Latanoprost contains the exact same active ingredient as Iyuzeh — Latanoprost 0.005%. The key difference is that generic Latanoprost contains the preservative benzalkonium chloride (BAK), while Iyuzeh does not.
Generic Latanoprost is the most direct substitute for Iyuzeh and is what most insurance plans prefer due to its low cost. If you don't have significant preservative sensitivity, this may work well for you.
Travatan Z is a prostaglandin analog that uses Travoprost 0.004% as its active ingredient. What sets it apart is that it's BAK-free — instead of benzalkonium chloride, it uses a preservative system called SofZia (containing boric acid, propylene glycol, sorbitol, and zinc chloride) that breaks down into gentle, non-irritating components on contact with the eye.
Travatan Z is often the best alternative for patients who need a BAK-free option but can't access Iyuzeh.
Lumigan uses Bimatoprost 0.01%, another prostaglandin analog. It's been on the market since 2001 and has a strong track record for lowering IOP. A generic version of Bimatoprost is also available.
Vyzulta is a newer prostaglandin analog with a dual mechanism of action. It's metabolized into Latanoprost acid (which works like Iyuzeh) and nitric oxide (which provides additional IOP-lowering through the trabecular meshwork pathway).
The best alternative depends on why you were prescribed Iyuzeh in the first place:
Always discuss any medication changes with your eye doctor. Don't switch or stop your glaucoma drops on your own — uncontrolled eye pressure can cause permanent vision damage.
Before switching to an alternative, make sure you've explored all your options for finding Iyuzeh. Check our guide on how to find Iyuzeh in stock near you, and use Medfinder to check real-time pharmacy availability. The manufacturer's home delivery program through PhilRx is another reliable option — learn more at myiyuzehsavings.com.
Iyuzeh is a unique medication because it's the only preservative-free Latanoprost on the market. If you can't fill your prescription, alternatives like generic Latanoprost, Travatan Z, Lumigan, and Vyzulta can all effectively lower eye pressure — but they each come with different preservative profiles and costs. Work with your eye doctor to find the option that's right for your eyes, your budget, and your availability situation.
