When You Can't Find Bimatoprost, You Still Have Options

Being unable to fill your Bimatoprost prescription is stressful, especially when you know that missing doses could put your vision at risk. Whether your pharmacy is out of stock, the cost is too high without insurance, or your insurance won't cover it, the last thing you should do is simply go without treatment.

The good news is that Bimatoprost is not the only medication in its class. There are several other prostaglandin analogs that work in a very similar way to lower eye pressure and protect your vision. Your eye doctor can help you switch to one of these alternatives safely.

Before we look at the alternatives, let's quickly review what Bimatoprost is and how it works — so you understand what you're looking for in a substitute.

What Is Bimatoprost?

Bimatoprost is a prescription eye medication approved by the FDA to treat open-angle glaucoma and ocular hypertension (high pressure inside the eye). It's sold under brand names like Lumigan (for glaucoma), Latisse (for eyelash growth), and Durysta (an intracameral implant).

Bimatoprost belongs to the prostaglandin analog class of medications. It's manufactured by AbbVie (formerly Allergan) and has been available since 2001. Generic versions are also available from several manufacturers.

For a complete overview, see our guide on what Bimatoprost is, its uses, and dosage.

How Does Bimatoprost Work?

Bimatoprost works by increasing the drainage of aqueous humor (the fluid inside your eye) through two pathways:

• Uveoscleral outflow: The primary pathway — Bimatoprost relaxes the ciliary muscle, allowing fluid to drain through the back of the eye more easily.
• Trabecular meshwork: Bimatoprost also increases outflow through this conventional drainage route near the front of the eye.

By increasing fluid drainage, Bimatoprost lowers the pressure inside the eye (intraocular pressure, or IOP). Lowering IOP is the most important thing you can do to slow or prevent vision loss from glaucoma.

Proven Alternatives to Bimatoprost

All of the medications below are prostaglandin analogs, meaning they work through similar mechanisms to lower eye pressure. Clinical studies have shown them to be effective treatments for glaucoma and ocular hypertension. However, they are not identical — they differ in potency, side effect profiles, preservatives, and cost.

Important: Never switch medications on your own. Always talk to your eye doctor before making a change.

1. Latanoprost (Xalatan)

Latanoprost is the most widely prescribed prostaglandin analog and is often the first-line treatment for open-angle glaucoma. It was approved by the FDA in 1996 and has a long track record of safety and efficacy.

• How it works: Increases uveoscleral outflow of aqueous humor, similar to Bimatoprost
• Dosing: One drop in the affected eye(s) once daily in the evening
• Efficacy: Lowers IOP by approximately 25-35%, comparable to Bimatoprost in most studies. Some research suggests Bimatoprost may have a slight edge in IOP lowering, but the difference is small.
• Side effects: Conjunctival hyperemia (eye redness) occurs less frequently than with Bimatoprost — about 5-15% vs. up to 45%. Iris pigmentation changes can still occur.
• Cost: Generic Latanoprost is one of the most affordable glaucoma medications — often $10-$25 with a discount card, making it significantly cheaper than Bimatoprost.
• Availability: Widely available at most pharmacies with multiple generic manufacturers

Latanoprost is an excellent alternative for most patients and is often easier to find and more affordable.

2. Travoprost (Travatan Z)

Travoprost is another well-established prostaglandin analog approved for reducing IOP in patients with open-angle glaucoma or ocular hypertension.

• How it works: Increases uveoscleral outflow, similar to Bimatoprost and Latanoprost
• Dosing: One drop in the affected eye(s) once daily in the evening
• Efficacy: Comparable to Bimatoprost in IOP-lowering ability. Clinical trials show similar reductions in eye pressure.
• Side effects: Conjunctival hyperemia, iris pigmentation changes, eyelash growth. The Travatan Z formulation uses a zinc-based preservative (sofZia) instead of benzalkonium chloride, which may be better tolerated by patients with sensitive eyes.
• Cost: Generic Travoprost typically costs $15-$50 with discount cards
• Availability: Generally well-stocked at most pharmacies

3. Tafluprost (Zioptan)

Tafluprost is a preservative-free prostaglandin analog that comes in single-use vials. It's an excellent option for patients who are sensitive to preservatives like benzalkonium chloride.

• How it works: Increases uveoscleral outflow to lower IOP
• Dosing: One drop in the affected eye(s) once daily in the evening
• Efficacy: Slightly less IOP-lowering potency than Bimatoprost in some studies, but still effective for many patients
• Side effects: Generally well-tolerated with lower rates of hyperemia and irritation due to preservative-free formulation
• Cost: Tends to be more expensive than Latanoprost and Travoprost — typically $50-$150 depending on insurance and discounts
• Availability: Available at most pharmacies but may need to be ordered

4. Latanoprostene Bunod (Vyzulta)

Latanoprostene Bunod is a newer prostaglandin analog with a dual mechanism of action. It was approved by the FDA in 2017.

• How it works: Combines a prostaglandin analog (Latanoprost acid) with a nitric oxide-donating group. This provides IOP lowering through both increased uveoscleral outflow and increased trabecular meshwork outflow.
• Dosing: One drop in the affected eye(s) once daily in the evening
• Efficacy: May provide slightly greater IOP reduction than Latanoprost alone due to the dual mechanism
• Side effects: Conjunctival hyperemia, eye irritation, eye pain, iris pigmentation changes
• Cost: Brand-only as of 2026, typically $150-$300+ without insurance
• Availability: Available at most pharmacies; may require prior authorization from insurance

How to Talk to Your Doctor About Switching

If you can't find Bimatoprost and need to discuss alternatives with your eye doctor, here are some questions to ask:

• Which alternative would work best for my specific type of glaucoma?
• Will switching medications affect my current eye pressure control?
• Are there any differences in side effects I should know about?
• Can I switch directly, or do I need a transition period?
• Is the alternative covered by my insurance?

Your doctor may also want to monitor your eye pressure more closely during the transition to make sure the new medication is working effectively.

Final Thoughts

Not being able to find Bimatoprost is frustrating, but it doesn't mean you're out of options. Latanoprost, Travoprost, Tafluprost, and Latanoprostene Bunod are all proven alternatives that can effectively lower your eye pressure and protect your vision.

Talk to your eye doctor about which option is right for you. And if you'd like to try finding Bimatoprost before switching, use Medfinder to check availability at pharmacies near you.
