Waking up with a swollen, red, or uncomfortable eye can feel very scary and confusing. When excess fluid builds up in the front part of your eye, your vision can become blurry and painful.
Your doctor might prescribe a special medicine called Sodium Chloride Ointment to fix this issue. This complete guide will help you understand how this medicine works, how to use it safely, and what to watch out for during your recovery.
Key Takeaways at a Glance

How Sodium Chloride Ointment Works in Your Eye
Simply put, this medicine is a high-strength salt solution, also known as a hypertonic saline ointment. Brand names like Muro 128 are very common for this type of treatment.
Think about what happens when you add salt to vegetables when making pickles. The salt naturally draws out the extra water.
A similar process happens in your eye. When extra fluid builds up in your cornea—the clear front surface of your eye—it causes uncomfortable swelling.
When you apply this ointment, it draws out that trapped fluid. By reducing this extra fluid, the medicine helps control the swelling and clears up your blurry vision.
Things to Tell Your Doctor Before Using This Medicine
Before your doctor prescribes this ointment, you must share important details about your health. Providing accurate information helps your doctor decide if this medicine is safe and right for you.
Be sure to mention the following details clearly:
- Any recent changes in your vision or sudden blurriness.
- Any current eye infections, open wounds, or previous eye injuries.
- Whether you wear contact lenses on a regular basis.
- Any known allergies to Sodium Chloride, other medicines, foods, or dyes.
- If you are currently pregnant, planning to become pregnant, or nursing a baby.
How to Apply the Ointment Correctly
Applying eye ointment is simple, but you must do it carefully and cleanly. Follow these step-by-step instructions for a safe application:
1. Wash Your Hands: Start by washing your hands thoroughly with soap and water, then dry them with a clean towel. This step is vital to stop germs from entering your eye.
2. Get Ready: Tilt your head back slightly and look up toward the ceiling. Use your clean index finger to pull your lower eyelid gently down to create a small pocket.
3. Apply the Medicine: Hold the ointment tube in your other hand. Never let the tip of the tube touch your eye, your fingers, or any other surface. This prevents bacteria from contaminating the tube. Gently squeeze a small ribbon of ointment—about one centimeter long—into the lower eyelid pocket.
4. Close Your Eye: Gently close your eye and keep it closed for about one minute to let the medicine spread evenly. Avoid squeezing your eyelids shut tightly.
5. Clean Up: Wipe away any extra ointment around your eyelids using a clean tissue.
6. Wash Hands Again: Wash your hands thoroughly with soap and water once more.
Most Important Rule: Never use the medicine more times than your doctor recommended. Even if your eye feels better, continue using it for the full length of time your doctor prescribed. Do not stop early.

What to Do for Missed Doses and Overdoses
