If you’ve noticed your dog's eye looks cloudy, hazy, or bluish, a common cause is corneal edema (a buildup of excess fluid). This is why so many pet owners begin searching for Muro 128 for dogs, as it’s the most common veterinary recommendation for this condition.

What many don’t realize is that the same formula long trusted in human care is available over the counter (OTC), with no prescription required. Even better, the leading generic, Rugby Sodium Chloride Ointment 5%, is made by Bausch & Lomb, the same manufacturer behind branded Muro 128. For an in-depth overview of human generics, see our Muro 128 Generic Alternatives Guide.

What Causes a Cloudy Eye in Dogs? Understanding Corneal Edema

That hazy, bluish, or cloudy appearance in a dog's eye is often a sign of corneal edema. While it is always essential to get a diagnosis from your veterinarian to rule out serious conditions like glaucoma or cataracts, corneal edema is one of the most common causes.

Simply put, corneal edema is a buildup of excess fluid inside the layers of the cornea (the clear, outer surface of the eye). This fluid buildup causes the cornea to swell and become opaque, which can be uncomfortable for your dog and can impair their vision. It can be caused by injuries, age-related conditions like endothelial dystrophy, or other eye issues.

To treat the swelling itself, veterinarians recommend a hypertonic solution. This is a special salt-based formula that works by gently drawing the excess fluid out of the cornea. This is precisely what Muro 128 (5% sodium chloride) is designed to do.

Why Vets Recommend Muro 128 for Dogs’ Eyes

Veterinarians often suggest 5% sodium chloride ophthalmic ointment when dogs (and sometimes cats) have corneal fluid buildup. Because vets frequently reference the Muro 128 brand, pet owners search for “Muro 128 for dogs” and run into mixed messages—especially on pet pharmacy sites that require prescriptions.

The Chewy Prescription Confusion

On pet marketplaces, you’ll often find sodium chloride ointment listed with an RX requirement—even though it’s OTC for human use. For example, Chewy lists generic sodium chloride ophthalmic ointment at $31.59 per box and requires a prescription: Chewy listing.

Human retailers like Xeteor sell the same strength (5%) as OTC, which means you can purchase it without a prescription.

Muro 128 (and the Rugby/Bausch & Lomb equivalent) comes in both ointment and solution (drops). Many vets prefer ointment at night because it stays in place longer, providing extended relief. Drops are often easier to apply during the day. If your vet specified one form, follow their guidance—both are 5% sodium chloride ophthalmic products designed to reduce corneal fluid buildup. For additional background on formats, strengths, and usage, see our Muro 128 Generic Alternatives Guide.
