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

If your eye doctor has prescribed Rocklatan, you may have questions about what it is, how it works, how to use it, and what to expect. This article covers everything you need to know as a patient in 2026.

What Is Rocklatan?

Rocklatan is a prescription ophthalmic solution (eye drop) manufactured by Alcon. It was first approved by the FDA in March 2019. Its generic name is netarsudil and latanoprost ophthalmic solution 0.02%/0.005%.

Rocklatan is a fixed-dose combination eye drop — meaning it contains two separate medications in a single bottle. Those two medications are:

• Netarsudil (0.02%) — a Rho kinase (ROCK) inhibitor; the first new class of glaucoma eye drop in over 20 years when it was approved in 2017
• Latanoprost (0.005%) — a prostaglandin analog and the most widely prescribed single-agent glaucoma eye drop in the world

What Is Rocklatan Used For?

Rocklatan is FDA-approved to reduce elevated intraocular pressure (IOP) — the fluid pressure inside the eye — in adults with:

• Open-angle glaucoma — the most common type of glaucoma, where the drainage angle in the eye becomes less efficient over time, causing pressure to build up. If untreated, high IOP damages the optic nerve, leading to progressive and irreversible vision loss.
• Ocular hypertension — elevated IOP without signs of glaucoma damage yet; treatment helps prevent future optic nerve damage.

Rocklatan is not typically a first-line therapy. Most eye doctors start with a single agent (like generic latanoprost) and add Rocklatan when more IOP reduction is needed. In clinical trials, Rocklatan reduced IOP 1–3 mmHg more than either of its components used alone.

How Do You Use Rocklatan?

The recommended dose of Rocklatan is one drop in the affected eye(s) once daily in the evening. Do not exceed one drop per eye per day — using it more often will not lower your IOP more and may increase side effects.

Administration tips:

• Tilt your head back, pull down the lower eyelid, and place one drop in the pocket formed. Close your eye gently and press lightly on the inner corner (nasolacrimal occlusion) for 1–2 minutes to help reduce systemic absorption.
• If you use other eye drops, wait at least 5 minutes between drops.
• Remove soft contact lenses before use and wait 15 minutes before reinserting.
• Do not touch the dropper tip to your eye, fingers, or any surface (contamination risk).
• If you miss a dose, skip it and take the next dose in the evening as scheduled. Do not double up.

How Do You Store Rocklatan?

Storage is an important consideration for Rocklatan:

• Before opening: Store in the refrigerator at 36°F–46°F (2°C–8°C). Keep in the original packaging and protect from light.
• After opening: You may keep the bottle in the refrigerator (until the expiration date) or at room temperature (up to 77°F / 25°C) for up to 6 weeks. Do not use after 6 weeks at room temperature.
