Silvadene (Silver Sulfadiazine)
Flamazine (Silver Sulfadiazine) Dosage and Side Effects
FLAMAZINE (silver sulfadiazine) belongs to the class of medications called topical antibiotics. It is used to treat and prevent infection of skin wounds, especially in victims of serious burns. It may also be used in leg ulcers, skin grafts, surgical incisions, and minor cuts and scrapes. It is applied directly to the wounded area and works by stopping the action of bacteria that may cause infection.
Proper Use of this medication
Burns: Clean burn wounds and apply FLAMAZINE (silver sulfadiazine) over all the affected areas to a depth of 3 mm to 5 mm.
One way to apply the cream is with a sterile gloved hand or a sterile nonmetallic spatula. Where necessary, reapply the cream to any area from which it has been removed by activity. Reapply the cream at least every 24 hours.
For hand burns and finger injuries, a recommended method is to apply the medication to the burn and then enclose the hand in a clear plastic bag or glove, which is then closed at the wrist. Change the dressing every 3 days or whenever there is a lot of drainage in the bag.
Silver sulfadiazine cream is also used for treatment of leg ulcers. Clean leg ulcer and fill the cavity with silver sulfadiazine to a depth of at least 3 mm to 5 mm. Avoid applying the silver sulfadiazine to the surrounding skin. Apply appropriate dressing to the area and change every 2 or 3 days.
Ask your health care professional about the best way to apply the cream and care for the affected area.
