Rocklatan (netarsudil/latanoprost ophthalmic solution) is a brand-name drug that’s prescribed in adults to help lower eye pressure. Rocklatan comes as an eye solution that’s typically applied once per day in the evening.

Rocklatan is approved by the Food and Drug Administration (FDA) to treat increased eye pressure in:

  • open-angle glaucoma, a condition where the pressure inside the eye (also called intraocular pressure or IOP) rises because the correct amount of fluid can’t drain out of the eye
  • ocular hypertension, a condition where IOP is high

Rocklatan is a combination of two medications: netarsudil and latanoprost. Netarsudil belongs to a drug class called rho kinase inhibitors. Latanoprost belongs to a drug class called prostaglandin analogs. Rocklatan is not available in a generic version.

Rocklatan comes as an eye solution. It’s applied to the affected eye as an eye drop in the evening, following these steps:

  1. Wash your hands before using Rocklatan.
  2. To apply, tilt your head back slightly and pull down your lower eyelid to create a small pocket.
  3. Hold the dropper above the eye, and squeeze a drop into this pocket.
  4. Close the eye and gently press a finger into the corner of the eye next to the nose. Hold for 1-2 minutes so the eye can absorb the drops.

Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious eye problems.

Wait at least 5 minutes before using any other eye drops your doctor has prescribed.

It may be helpful to apply Rocklatan around the same time each day. This helps maintain a steady level of the drug in your eye so Rocklatan can work effectively.

Do not use Rocklatan while wearing soft contact lenses. This medication could permanently stain the lenses. Use it at least 15 minutes before inserting your contact lenses.

Make sure to follow your doctor’s dosing instructions very carefully. Use only the number of drops your doctor has prescribed.

If you have questions about how to use Rocklatan, talk with your doctor or pharmacist.


Some pharmacies offer labels with large print, braille, or a code you scan with a smartphone to convert text to speech. If your local pharmacy doesn’t have these options, your doctor or pharmacist might be able to recommend a pharmacy that does.

If you’re having trouble opening medication bottles, ask your pharmacist about putting Rocklatan in an easy-open container. They also may recommend tools that can make it easier to open bottles.

If you miss a dose of Rocklatan, skip the missed dose and apply your next scheduled dose in the evening. Do not apply two doses in one day to make up for the missed one. If you’re not sure what to do, talk with your doctor or pharmacist.

To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or putting a note where you’ll see it, such as on your bathroom mirror or bedside table. You could also download a reminder app on your phone.

It’s important that you do not use more Rocklatan than your doctor prescribes. For some medications, taking more than the recommended amount may lead to harmful effects or overdose.

If you use more than the recommended amount of Rocklatan
