Applies to the following strengths: 85 mg/g; 5%

Usual Adult Dose for Bacterial Infection

Topical Cream: Apply with a sterile gloved hand to cleansed and debrided burn wounds once or twice a day, to a thickness of about 1/16 inch

Topical Solution: Grafted area should be covered with 1 layer of fine mesh gauze; an 8-ply burn dressing (cut to size of graft) should be wetted with this solution using an irrigation syringe and/or irrigation tubing until leaking noticeable; gauze dressing should be kept wet by:
-Irrigating with a syringe or injecting solution into irrigation tubing every 4 hours or as needed OR
-If irrigation tubing not used, by moistening gauze dressing every 6 to 8 hours or as needed to keep wet

Comments:
-Topical cream: Application thicker than 1/16 inch is not recommended.
-Topical cream: The cream should be reapplied whenever it is removed from any area (e.g., by patient activity) to always keep burned areas covered with this drug.
-Topical cream: Dressings are not usually necessary; however, if the patient requires them, only a thin layer of dressings should be used.
-Topical cream: Duration of therapy depends on patient requirements; treatment generally continued until healing is progressing well or until burn site is ready for grafting.
-Topical solution: If irrigation tubing used, it should be placed over the burn dressing in contact with the wound and covered with second piece of 8-ply dressing; irrigation dressing should be secured with a bolster dressing and wrapped as appropriate.
-Topical solution: May leave wound dressings undisturbed, except for irrigations, for up to 5 days; additional soaks may be started until graft take is complete.
-Topical solution: Maceration of skin may result from wet dressings applied for intervals as short as 24 hours.
-Topical solution: Treatment generally continued until autograft vascularization occurs and healing is progressing (usually in about 5 days); safety and efficacy not established for longer than 5 days for an individual grafting procedure.

Uses:
-Topical cream: As adjunctive therapy of patients with second- and third- degree burns
-Topical solution: As an adjunctive topical antimicrobial agent to control bacterial infection when used under moist dressings over meshed autografts on excised burn wounds
