Alternatives to Travoprost If You Can't Fill Your Prescription

Travoprost (Travatan Z) is a highly effective first-line treatment for open-angle glaucoma and ocular hypertension. But if your pharmacy is out of stock and you need to keep your intraocular pressure (IOP) under control, the good news is that several strong alternatives exist within the same drug class. Here's what you need to know about switching medications — and when it's safe to do so.

Can You Just Skip Travoprost If You Can't Find It?

Short answer: try not to. Travoprost works by keeping fluid continuously draining from the eye. Missing one or two doses likely won't cause permanent harm — clinical data shows travoprost maintains meaningful IOP control for up to 84 hours post-dose — but extended gaps allow pressure to rise. Elevated IOP over time is what damages the optic nerve. If you know you'll be without medication for more than two or three days, contact your ophthalmologist immediately to discuss a bridge option.

Best Alternative #1: Latanoprost (Xalatan)

Latanoprost is the most widely prescribed prostaglandin analog in the United States and the most direct alternative to travoprost. Both work by the same mechanism — increasing aqueous humor outflow through the uveoscleral pathway — and are dosed once daily in the evening. Clinical studies show comparable IOP reduction of 7–8 mmHg for both drugs.

Latanoprost also has an important cost advantage: with GoodRx or SingleCare discount cards, generic latanoprost is available for as low as $8–15 per bottle — dramatically cheaper than travoprost's $28–50 discounted price. Side effects are similar to travoprost, including eye redness, iris pigmentation changes, and eyelash growth.

One practical tip: latanoprost requires refrigeration after opening (unlike Travatan Z, which can be stored at room temperature until the expiration date). Keep this in mind if your doctor switches you.

Best Alternative #2: Bimatoprost (Lumigan)

Bimatoprost (brand name Lumigan) is another prostaglandin analog that lowers IOP with once-daily evening dosing. Some studies suggest bimatoprost may provide slightly greater IOP reduction (1–2 mmHg more) compared to latanoprost and travoprost, making it an option for patients with particularly high pressures. Generic bimatoprost is widely available and typically priced around $35–50 per bottle with discount cards.

Bimatoprost is also available as an intracameral implant (Durysta) for patients who struggle with daily eye drops. Your ophthalmologist can discuss whether this is an option for your situation.

Best Alternative #3: Tafluprost (Zioptan)

Tafluprost (Zioptan) is the only preservative-free prostaglandin analog available in single-use vials. This makes it an excellent choice for patients with significant ocular surface disease, dry eye, or sensitivity to preservatives like benzalkonium chloride. It works the same way as travoprost and is dosed once daily. Generic tafluprost is available. IOP-lowering efficacy is comparable to other prostaglandin analogs.

Best Alternative #4: Timolol (Timoptic)

Timolol is a beta-blocker eye drop that lowers IOP by reducing the production of aqueous fluid (rather than increasing outflow). It's one of the oldest and most affordable glaucoma medications, with generic versions available for under $15 at most pharmacies. Timolol is typically dosed twice daily and is often used in combination with prostaglandin analogs. It's not a first-line substitute for travoprost but can provide meaningful IOP control while you search for your medication.

Important: Timolol is contraindicated in patients with asthma, COPD, bradycardia, or heart block. Always discuss with your doctor before starting.

Comparing Travoprost Alternatives at a Glance

Latanoprost (Xalatan): Closest alternative, lowest cost (~$8–15 with discount card), once daily, same mechanism

Bimatoprost (Lumigan): Slightly stronger IOP reduction, once daily, generic available (~$35–50 with discount card)

Tafluprost (Zioptan): Preservative-free single-use vials, best for sensitive eyes, once daily

Timolol (Timoptic): Different mechanism (beta-blocker), twice daily, very affordable, not for asthma/COPD patients

What to Tell Your Doctor When Requesting an Alternative

Call your ophthalmologist or optometrist and explain: 'My pharmacy doesn't have travoprost in stock and I need a refill. Can you send a temporary prescription for latanoprost or another prostaglandin analog?' Most eye doctors understand this is a real problem and can send an e-prescription quickly. Be sure to mention any allergies, preservative sensitivities, or other eye conditions.

Important: Don't Use Two Prostaglandin Analogs at Once

One critical point: you should never use two prostaglandin analog eye drops at the same time. Using travoprost AND latanoprost (or any other prostaglandin) together can actually decrease the IOP-lowering effect or cause paradoxical IOP elevation. If you're switching to an alternative, stop your travoprost and use only the replacement as directed by your doctor.
