It is used to treat severe burns. It is used topically as an adjunctive therapy for second- and third-degree burns. It is bacteriostatic against many gram-positive and gram-negative organisms, including Pseudomonas aeruginosa. Some sources state that mafenide is more appropriate for non-facial burns, while chloramphenicol/prednisolone or bacitracin are more appropriate for facial burns.
Adverse reactions can include superinfection, pain or burning upon application, rash, pruritus, tachypnea, or hyperventilation. Mafenide is metabolized to a carbonic anhydrase inhibitor, which could potentially result in metabolic acidosis.
For use as adjunctive therapy for second- and third-degree burns to prevent infection, adults and children should apply topically to a thickness of approximately 1.6 mm to cleaned and debrided wound once or twice per day with a sterile gloved hand. The burned area should be covered with cream at all times.
