Alternatives to Latanoprost If You Can't Fill Your Prescription

Latanoprost is the most commonly prescribed glaucoma eye drop in the United States, but it's not always the easiest to find in stock. If your pharmacy is out, or if you're experiencing intolerable side effects, there are several effective alternatives your eye doctor can prescribe. This guide covers the top alternatives to latanoprost, how they compare, and what to discuss with your ophthalmologist or optometrist.

Why You Should Never Stop Latanoprost Without a Plan

Before exploring alternatives, a critical warning: never simply stop using latanoprost or any glaucoma eye drop without consulting your eye doctor. Glaucoma is a progressive disease that causes permanent vision loss when intraocular pressure (IOP) rises unchecked. Always have a plan in place — ideally coordinated with your prescriber — before switching to an alternative.

Alternative #1: Bimatoprost (Lumigan)

Bimatoprost is a prostaglandin analogue (marketed as Lumigan) that works through the same general mechanism as latanoprost — increasing uveoscleral outflow. It is FDA-approved for open-angle glaucoma and ocular hypertension.

Efficacy: Slightly stronger IOP reduction than latanoprost in some studies (7–9 mmHg vs. 6–8 mmHg). May be preferred for patients with higher baseline pressures.

Side effects: More conjunctival hyperemia (redness) than latanoprost — up to 44% of patients report noticeable redness. Similar iris darkening and eyelash changes.

Cost: Generic bimatoprost costs significantly more than generic latanoprost — typically $50–$270 per bottle at retail, compared to $8–$33 for latanoprost. Manufacturer co-pay cards may help commercially insured patients.

Best for: Patients who need stronger IOP control, or whose latanoprost is unavailable and insurance covers bimatoprost well.

Alternative #2: Travoprost (Travatan Z)

Travoprost (Travatan Z) is another prostaglandin analogue with efficacy nearly identical to latanoprost. It was FDA-approved in 2001 and is available in both preserved and preservative-free formulations.

Efficacy: IOP reduction of approximately 6–8 mmHg — virtually equivalent to latanoprost. Both are dosed once daily in the evening.

Advantage: Travatan Z uses polyquad as a preservative instead of benzalkonium chloride (BAK), which may cause less ocular surface irritation for sensitive patients. Preservative-free formulations are also available.

Cost: Generic travoprost is available; retail prices average $100–$190 per bottle, with GoodRx prices as low as $28–$50. More expensive than latanoprost but less expensive than bimatoprost.

Best for: Patients with benzalkonium chloride sensitivity, dry eye disease, or those who've tried latanoprost with poor tolerance.

Alternative #3: Tafluprost (Zioptan)

Tafluprost (Zioptan) is the newest prostaglandin analogue in this class, FDA-approved in 2012. Its most distinctive feature is its fully preservative-free formulation, packaged in single-use containers.

Efficacy: IOP reduction of approximately 25–27% — comparable to latanoprost despite a lower concentration (0.0015% vs. 0.005%).

Advantage: Least associated with conjunctival hyperemia and iris color changes among the prostaglandin analogues. Ideal for patients with very sensitive eyes or documented benzalkonium chloride toxicity.

Cost: Generally the most expensive option in the prostaglandin class. Generic tafluprost is available but pricing varies; retail can be $150–$300+ per box of single-use vials without discounts.

Best for: Patients with documented dry eye disease, preservative sensitivity, or long-term chronic use where minimizing ocular surface toxicity matters most.

Alternative #4: Timolol (Timoptic)

Timolol is a beta-blocker eye drop that works through an entirely different mechanism — it reduces the production of aqueous humor rather than increasing its outflow. It has been used for glaucoma since the 1970s.

Efficacy: IOP reduction of approximately 20–27%. Generally less effective than prostaglandins as monotherapy.

Cautions: Can cause systemic effects — slowed heart rate, lowered blood pressure, and potential issues for patients with asthma, COPD, or certain heart conditions. Discuss your medical history with your doctor before switching.

Cost: One of the least expensive glaucoma drops available. Generic timolol 0.5% is widely available for a few dollars per bottle with a discount card.

Choosing the Right Alternative: Talk to Your Eye Doctor

The right alternative depends on your baseline IOP, history with each medication, insurance coverage, and tolerance for side effects. Your ophthalmologist or optometrist is the best person to guide this decision. If latanoprost is simply out of stock locally, use medfinder to search nearby pharmacies while your doctor decides on next steps. See also: why is latanoprost hard to find?.
