About SULFAMYLON
What is this medication?
Sulfamylon is a prescription topical antibiotic primarily used to prevent and treat bacterial infections in patients with severe burns. The active ingredient is mafenide acetate, which belongs to the sulfonamide class of medications. It works by inhibiting the growth of a wide range of bacteria, including those that are often resistant to other types of antibiotics, helping to keep the burn wound clean and promoting the healing process.
This medication is commonly available as a cream or as a solution for topical application. When used on second or third-degree burns, it helps lower the risk of wound sepsis, which is a life-threatening infection that can spread through the body. It is important to apply the medication exactly as directed by a healthcare professional, as it can sometimes cause side effects like pain, burning, or allergic reactions at the site of application.

How to read this:plans on the same formulary share tier + PA rules. Your specific plan's copay depends on (a) the tier above, (b) your plan's cost-share for that tier, (c) whether you're in the initial coverage phase or past the 2026 $2,000 out-of-pocket cap. For your exact plan, check its Summary of Benefits or log in to your Medicare.gov account. Copay cards don't apply to Medicare (federal law).
