What Is Lumigan? Uses, Dosage, and What You Need to Know in 2026

Lumigan (bimatoprost ophthalmic solution) is a prescription eye drop used primarily to treat glaucoma and high eye pressure. First approved by the FDA in 2001, Lumigan has been a first-line treatment for open-angle glaucoma for more than two decades. This guide covers everything you need to know about Lumigan — what it does, how to use it, what side effects to expect, and what it costs.

What Is Lumigan (Bimatoprost)?

Lumigan is the brand name for bimatoprost ophthalmic solution, manufactured by Allergan (an AbbVie company). It belongs to a class of drugs called prostaglandin analogs — specifically, it is a synthetic prostamide analog that mimics naturally occurring substances in the eye to lower intraocular pressure (IOP).

Bimatoprost is available under multiple brand names and formulations:

Lumigan 0.01%: Prescription eye drops for glaucoma and ocular hypertension (brand)

Generic bimatoprost 0.03%: Same active ingredient, lower cost, available from multiple manufacturers

Latisse 0.03%: Same active ingredient, FDA-approved for cosmetic eyelash growth only

Durysta: Bimatoprost intravitreal implant, injected into the eye by a healthcare professional

What Is Lumigan Used For?

Lumigan is FDA-approved for:

Open-angle glaucoma: The most common form of glaucoma, where the eye's drainage system becomes less efficient over time. Lumigan helps fluid drain more effectively, lowering pressure and protecting the optic nerve.

Ocular hypertension: High IOP without glaucoma damage yet. Treating elevated IOP reduces risk of future optic nerve damage.

Bimatoprost (Latisse formulation) is also approved for eyelash hypotrichosis — inadequate eyelash growth — applied to the upper eyelid base for cosmetic purposes.

How Effective Is Lumigan at Lowering Eye Pressure?

Lumigan is one of the most effective single-agent eye drops available for lowering IOP. In a 12-month clinical study, Lumigan 0.01% lowered IOP by up to 7.5 mmHg from a baseline average of 23.5 mmHg. Clinical trials show that bimatoprost reduces IOP by approximately 25–30% from baseline — making it among the most potent prostaglandin analogs available.

Lumigan Dosage: How to Take It

The standard dosage is:

One drop in the affected eye(s)

Once daily, in the evening

Do NOT use more than once daily. More frequent use of prostaglandin analogs can actually decrease their effectiveness. IOP reduction starts approximately 4 hours after the first dose and peaks at 8–12 hours, lasting the full 24-hour cycle.

How to Apply Lumigan Eye Drops: Step by Step

Wash your hands thoroughly with soap and water.

If you wear soft contact lenses, remove them. Wait 15 minutes after using Lumigan before reinserting.

Tilt your head back and gently pull down your lower eyelid to create a small pocket.

Hold the bottle upside down over your eye and gently squeeze 1 drop into the pocket. Do NOT let the dropper tip touch your eye.

Close your eye and lightly press the inner corner (nasolacrimal duct area) for 1–2 minutes. This helps keep the medication in the eye and reduces systemic absorption.

Gently blot away any excess medication around the eye with a clean tissue.

Wash your hands again.

If you use multiple eye drops, wait at least 5 minutes between each medication.
