## FAQ

- What does Muro 128 do for your eyes? — The 5% sodium chloride draws excess fluid out of a swollen cornea by osmosis, which the FDA OTC monograph describes as temporary relief of corneal edema.
- Is it sold over the counter, or does it need a prescription? — Both the solution and the ointment sell over the counter as FDA OTC monograph drugs.
- What is hypertonic saline, and why 5 percent? — Hypertonic means saltier than the fluid in the tissue it touches.
- Who manufactures the brand? — Bausch + Lomb manufactures the line and has done so since 1986.
- What is the difference between the drops and the ointment? — Drops spread thin and clear quickly, which is why they carry the daytime load at 1 to 2 drops every 3 to 4 hours.
- Is this the same as regular sodium chloride saline? — Regular saline sits at 0.9%, matched to body fluid, and does nothing osmotically to a swollen cornea.
- Is the formula preservative-free? — Preservative-free is not the claim on this carton.
- What is the active ingredient? — Sodium chloride at 5% hypertonicity, in the solution and in the ointment alike.
