Why Is Combigan So Hard to Find? [Explained for 2026]

If you've arrived at your pharmacy to pick up Combigan and left empty-handed, you're not alone. Patients managing glaucoma or ocular hypertension with Combigan (brimonidine tartrate/timolol maleate) occasionally run into stocking problems — even though Combigan is not currently on the FDA drug shortage list. Here's a plain-English explanation of why this happens and what you can do about it.

What Is Combigan and Who Uses It?

Combigan is a prescription eye drop that combines two active ingredients — brimonidine tartrate (0.2%) and timolol maleate (0.5%) — in a single bottle. It was FDA-approved in 2007 and manufactured by AbbVie (formerly Allergan). By 2020, it was the 256th most-prescribed medication in the United States, with more than 1 million prescriptions filled annually. It's used specifically to lower intraocular pressure (IOP) in people with open-angle glaucoma or ocular hypertension.

Combigan is not a first-line treatment — it's typically added when a single glaucoma medication isn't controlling pressure well enough. That means patients on Combigan often have more complex cases and cannot easily skip doses without risking optic nerve damage and vision loss.

Is Combigan on the FDA Shortage List?

No. As of 2026, Combigan is not listed on the FDA's current drug shortage database or the ASHP (American Society of Health-System Pharmacists) shortage list. That's the good news. But "not on the shortage list" doesn't mean "available at every pharmacy near you right now."

So Why Can't I Find It at My Pharmacy?

Several factors explain why Combigan can still be hard to locate despite no official shortage:

• Brand vs. generic confusion: Generic brimonidine/timolol received FDA approval in April 2022. Many pharmacies switched their default stock to the generic, meaning the brand-name Combigan may not sit on shelves regularly. If your prescription says "brand only," your pharmacy may need to special-order it.
• Small pharmacy inventory: Eye drop medications, including Combigan, are stocked in smaller quantities than high-volume pills. A single wave of prescriptions can temporarily clear out a pharmacy's entire supply.
• Insurance formulary routing: Some insurance plans route patients to mail-order pharmacies or specific preferred pharmacies. If your plan requires prior authorization and the PA hasn't been approved yet, your local pharmacy may decline to fill the prescription regardless of stock.
• Supply chain volatility: Ophthalmic solutions use specialized sterile manufacturing. Even minor disruptions at a manufacturer or distributor can delay restocking at local pharmacies for days or weeks.
• Geographic variation: Rural areas and smaller towns often have fewer pharmacy options and less consistent stock of specialty eye drops compared to urban areas.

Does the Brand Name vs. Generic Matter?

Generic brimonidine tartrate/timolol maleate contains the same active ingredients at the same concentrations (0.2%/0.5%) and is FDA-rated as therapeutically equivalent to brand Combigan. For most patients, the generic works just as well. The difference may show up in preservatives or bottle design, so a small number of patients notice tolerability differences — talk to your eye doctor if you switch and experience new irritation.

The generic is also significantly cheaper. Without insurance, brand Combigan averages around $278 for a 5 mL bottle, while the generic can be as low as $24–$34 with a GoodRx coupon.

What Should I Do If I Can't Find Combigan?

Here are the steps to take immediately:

1. Ask about the generic: Ask your pharmacist if brimonidine tartrate/timolol maleate is in stock. If your prescription is written for brand only, ask your eye doctor to authorize a generic substitution.
2. Call multiple pharmacies: Pharmacy stock varies widely by location. Don't assume your one pharmacy represents everyone — call a few nearby.
3. Use medfinder: [@portabletext/react] Unknown block type "span", specify a component for it in the `components.types` prop calls pharmacies near you to check which ones have Combigan in stock, so you don't have to spend hours on hold.
4. Ask your doctor about a bridge supply: If your glaucoma is actively being managed, your ophthalmologist may have samples or can prescribe a temporary alternative to protect your vision while you locate your medication.
5. Consider an alternative medication: Options like Cosopt (dorzolamide/timolol) or Simbrinza (brinzolamide/brimonidine) may be in stock at your pharmacy. See our guide on [@portabletext/react] Unknown block type "span", specify a component for it in the `components.types` prop for more details.

Never Stop Combigan Without Talking to Your Doctor

This is critical: if you can't find Combigan, do not simply stop using it. Glaucoma is a progressive disease, and uncontrolled eye pressure can permanently damage your optic nerve. Even a few days without medication can allow pressure to spike. Contact your eye doctor immediately if you cannot fill your prescription.

The Bottom Line

Combigan availability is generally good in 2026, but localized gaps do happen — especially for the brand-name version. The most effective step you can take is to check multiple pharmacies or use a service like medfinder that does the calling for you. And if finding it remains a challenge, your eye doctor can discuss approved alternatives that protect your vision in the meantime.
