Sulfamylon Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Sulfamylon (mafenide acetate) is used to prevent infection in severe burn wounds. It is a topical (for the skin) antibiotic. Common side effects include pain, burning, or redness.
Clean the affected area, and apply a dose of Sulfamylon to the wound while wearing a clean pair of medical gloves (e.g., latex, vinyl), once or twice daily or as directed by your doctor. The layer of cream should be about one-sixteenth of an inch (1 to 2 millimeters) thick. Cover the wound with this medication at all times. If the cream rubs off the wound, re-apply it immediately. Length of treatment is based on the patient's medical condition and response to treatment. It is not likely that other drugs you take orally or inject will have an effect on topically applied Sulfamylon. But many drugs can interact with each other. Tell your doctor all prescription and over-the-counter medications and supplements you use. During pregnancy, Sulfamylon should be used only when prescribed. It is unknown if this drug passes into breast milk. Consult your doctor before breast-feeding.

Sulfamylon FDA Prescribing Information: Side Effects
In the clinical setting of severe bums, it is often difficult to distinguish between an adverse reaction to mafenide acetate and bum sequelae. In a clinical study of pediatric patients with acute bums requiring autografts who received SULFAMYLON® (mafenide acetate) 5% SOLUTION in addition to double antibiotic solution (DAB) wound therapy (neomycin sulfate 40 mg and polymyxin B 200,000 units/liter), the incidence of rash (4.6%) and itching (2.8%) in the group which received SULFAMYLON® (mafenide acetate) 5% Solution was not different from that experienced with (DAB) dressings alone (5.7% and 1.3%, respectively).
From other clinical settings, a single case of bone marrow depression and a single case of an acute attack of porphyria have been reported following therapy with mafenide acetate. Fatal hemolytic anemia with disseminated intravascular coagulation, presumably related to a glucose-6-phosphate dehydrogenase deficiency, has been reported following therapy with mafenide acetate. The following adverse reactions have been reported with topical mafenide acetate therapy:
Dermatologlc and Allergic: Pain or burning sensation, rash and pruritus (often localized to the area covered by the wound dressing), erythema, skin maceration from prolonged wet dressings, facial edema, swelling, hives, blisters, eosinophilia.
