How does Flamazine work? What will it do for me?

It is applied directly to the wounded area and works by stopping the action of bacteria that may cause infection.

How should I use Flamazine?

Burns: Clean burn wounds and apply 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.

Are there any other precautions or warnings for Flamazine?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Allergy to sulfonamides: Some people who are allergic to sulfonamide antibiotics, such as sulfamethoxazole also experience allergic reactions to silver sulfadiazine. Before you use this medication, inform your doctor about any previous side effects you have had to other antibiotics. Contact your doctor at once if you experience signs of an allergic reaction, such as skin rash, itching, difficulty breathing, or swelling of the face and throat.

Glucose 6 phosphate dehydrogenase deficiency: Silver sulfadiazine should be used with caution by people with a history of G-6-PD (glucose 6 phosphate dehydrogenase) deficiency, as hemolysis (breakdown of blood cells) may occur.

Liver and kidney function: Silver sulfadiazine should be used with caution by people with significant liver or kidney impairment. If you are using this medication to treat large wounds it is important to drink lots of liquids to prevent dehydration and kidney damage.

Oral hypoglycemic agents and phenytoin: For people with large area burns where serum sulfadiazine levels may approach therapeutic levels, the action of antidiabetic agents and phenytoin may be increased, and it is recommended that blood levels be monitored.

Overgrowth of organisms: The use of antibiotics occasionally results in the overgrowth of organisms that the antibiotics don’t kill, such as other bacteria or fungi and organisms. This can cause other infections, such as yeast infections, to develop. If you experience new symptoms while using silver sulfadiazine, contact your doctor.

Pregnancy: The safety of silver sulfadiazine has not been established for use during pregnancy. Silver sulfadiazine should only be used by badly burned pregnant women if the benefits outweigh the risks. Silver sulfadiazine should not be used by a pregnant woman near term.

Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are using silver sulfadiazine, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
