Your eyes are among the most precious parts of your body. Sometimes, the fluid pressure inside your eyes can rise to unhealthy levels, leading to serious conditions like glaucoma. If your doctor has prescribed Netarsudil eye drops for this condition, you likely have questions about how it works and how to use it safely.
Managing eye pressure requires careful daily habits and a clear understanding of your medicine. This complete guide will walk you through everything you need to know in simple, easy-to-understand English so you can protect your vision with confidence.
Key Takeaways
- Netarsudil helps lower high fluid pressure inside the eye for glaucoma patients.
- Always wash your hands before and after applying your eye drops.
- Wait at least 15 minutes before putting your contact lenses back in after your dose.
- Never share your prescribed eye drops with anyone else, even if they have similar symptoms.
- Store the bottle properly in the refrigerator or at room temperature based on how long it has been open.
What Does This Medicine Actually Do?
Simply put, Netarsudil is a prescription eye drop used to treat conditions like glaucoma where fluid pressure inside the eye is too high. High eye pressure can quietly damage your optic nerve over time and lead to vision loss if it is left unchecked.
This medicine works by helping to reduce the amount of fluid produced inside your eye and improving fluid drainage. Lowering this internal pressure helps protect your eyes from further damage and preserves your sight. Your doctor may prescribe this medicine under the common brand name Rhopressa.
Things to Tell Your Doctor Before Using This Medicine
Before you start using Netarsudil, your doctor needs a complete picture of your health history. Sharing this information keeps you safe and helps prevent unwanted complications. Make sure to tell your doctor about the following important details:
- Eye Infections or Injuries: Tell your doctor if you currently have any eye infections, open wounds, or other physical eye injuries.
- Contact Lenses: Let your doctor know right away if you wear contact lenses daily or sometimes.
- Allergies: Inform your doctor if you are allergic to Netarsudil or to benzalkonium chloride, which is a common preservative found in many eye drops. Also report any past reactions to other medicines, foods, preservatives, or dyes.
- Pregnancy: Tell your doctor if you are pregnant, planning to become pregnant, or nursing a baby.
- Breastfeeding: Let your doctor know if you are currently breastfeeding so they can ensure the safety of your baby.
How Do You Use This Eye Drop Correctly?
This medicine is designed for your eyes only. Never take it by mouth under any circumstances. Always use the exact dose and schedule prescribed by your doctor without making changes on your own.
1. Clean Your Hands First: Wash your hands thoroughly with soap and water before and after handling the eye drop bottle.
2. Find the Right Position: Tilt your head back slightly and gently pull down your lower eyelid with your clean index finger to create a small pocket.
3. Apply with Care: Hold the dropper tip close to your eye without touching your eye, eyelids, or fingers. Touching the tip can introduce harmful germs into the liquid.
4. Release One Drop: Squeeze the bottle gently to release a single drop into the pocket you created in your lower eyelid.
5. Close Your Eye Gently: Close your eye softly right after putting the drop in. Avoid blinking rapidly or rubbing your eye.
6. Press Gently on the Corner: To help the medicine stay inside your eye longer, gently press your finger against the inner corner of your eye near your nose for a minute.
7. Follow Your Schedule: Use your eye drops at the exact times recommended by your doctor. Never use more drops than prescribed.
Special Note for Children: If this medicine is being given to a child, always get specific instructions and guidance from your pediatrician or eye doctor before starting treatment.
What Should You Do If You Miss a Dose?
Do not panic if you happen to miss a scheduled dose of your eye drops. Simply skip the missed dose and continue with your next scheduled dose at the normal time.
Never try to make up for a missed dose by putting in a double dose. Taking extra drops will not help and may increase your risk of having unpleasant side effects.
What If Too Much Medicine Gets Into Your Body?
If you accidentally use far too much medicine or if someone swallows the liquid by mistake, take action right away. Call your local emergency services or poison control center right away.
If you are in the United States or Canada, call 911 or contact poison control. If you are in the United Kingdom, call 999 or go straight to the nearest hospital Emergency Department (ER or A&E) for immediate medical evaluation.
Using Other Products With This Medicine
Never use any other eye drops or eye ointments unless your doctor explicitly tells you it is safe. Mixing products can alter how your medicines work or cause irritation.
Give your doctor a complete list of all the items you take, including prescription pills, over-the-counter medicines, herbal remedies, and dietary supplements. Also let them know if you smoke or drink alcohol regularly, as some substances can interact with your treatments.
