Sometimes, the pressure inside your eyes builds up slowly without you even noticing it. Think of it like a bicycle tire that slowly gets too much air pumped inside. In medical terms, doctors call this condition glaucoma or high eye pressure. If left untreated, this extra pressure can damage your optic nerve, which carries visual signals to your brain. Over time, this damage can lead to a gradual loss of your vision.
Did your doctor recently prescribe a new combination of eye drops to help manage this exact condition? If so, this complete guide is designed to help you understand everything you need to know. Let us break down how these medicines work, how to use them safely, and what side effects you might experience during your treatment journey.
Key Takeaways
- These eye drops combine two active medicines to lower high pressure inside the eye effectively.
- Always wash your hands before and after applying your drops, and avoid touching the dropper tip.
- Some side effects, such as changes in eye color or eyelash growth, can become permanent over time.
- Store unopened bottles in the refrigerator, and track expiration dates carefully after opening.
- Never share your prescription eye drops with family members or friends under any circumstances.

What Are These Eye Drops?
The eye drops prescribed by your doctor contain a powerful combination of two different active medical ingredients. These two ingredients are Netarsudil and Latanoprost. Sometimes, your prescription bottle or packaging may also be known by the brand name Rocklatan.
Both of these medicines work together as a team to help your eyes function better. Their main job is to help the extra fluid inside your eye drain out more easily. By improving this fluid drainage, the drops successfully lower the overall pressure inside your eye. In simple terms, this is a very effective medical treatment designed to protect your vision.
Things to Tell Your Doctor Before Using This Medicine
Before you start using this new prescription, your doctor needs a complete overview of your current health history. This ensures the treatment is safe and effective for your specific needs. If any of the following situations apply to you, please let your doctor know right away.
- Eye Injuries or Infections: If you have recently experienced any eye injury, active infection, or unusual inflammation in or around your eye.
- Contact Lenses: If you wear soft or hard contact lenses on a regular basis.

Check Availability →How to Use This Medicine Correctly
This medicine is meant strictly as eye drops and must never be swallowed or taken by mouth. To get the absolute best results from your treatment, follow these simple step-by-step instructions every single day.
1. Wash Your Hands: Always wash your hands thoroughly with soap and water before and after handling your eye drops.
2. Prepare Your Eye: Tilt your head back slightly and look up at the ceiling. Use your clean index finger to pull your lower eyelid down gently to create a small pocket.
3. Apply the Drop: Hold the bottle upside down above your eye. Be very careful not to let the dropper tip touch your eye, your eyelashes, or your fingers. Squeeze exactly one drop into the pocket.
4. Close Your Eye: After putting the drop in, close your eye gently. Do not blink rapidly or rub your eye. Keep your eye closed for about one full minute.
5. Wait Between Medicines: If you use other types of eye drops, wait at least five minutes between each different medicine.
The most important rule is to use your medicine exactly as your doctor prescribed, at the exact scheduled times. Never use more drops than recommended, even if you feel your symptoms are not improving quickly enough.
What to Do If You Miss a Dose
If you accidentally miss a scheduled dose of your eye drops, do not panic or rush. Simply skip that missed dose entirely and continue with your normal routine at the next scheduled time, usually in the evening. Never use extra drops to make up for a missed dose.
What to Do If You Use Too Much
If you suspect that you accidentally put too much medicine into your eye, stay calm and seek medical advice promptly. Contact your local emergency services, call your national poison control center, or go directly to the nearest hospital emergency department for guidance.
Things to Watch Out For While Using This Medicine
While you are using these eye drops, there are a few important lifestyle and health factors you should keep in mind.
- Regular Doctor Visits: Keep all scheduled appointments with your eye doctor so they can measure your eye pressure and track your progress.
- Changes in Eye Color: This is a very important detail to remember. Over time, this medicine can permanently change the color of your colored part of the eye (iris), eyelids, and eyelashes. Your eyelashes may also grow longer, thicker, and darker. These pigment changes can be permanent. If you only treat one eye, you may notice a visible difference between your two eyes. Talk to your doctor if you notice these changes.
- Contact Lenses: If you wear contact lenses, take them out before applying your eye drops. Wait at least 15 minutes after putting the drops in before putting your lenses back into your eyes.
- Sensitivity to Light: If these drops make your eyes feel sensitive to bright sunlight, wear dark sunglasses when you go outside.
