Silver sulfadiazine, sold under the brand Silvadene among others, is a topical antibiotic used in partial thickness and full thickness burns to prevent infection. Tentative evidence has found other antibiotics to be more effective, and therefore it is no longer generally recommended for second-degree (partial-thickness) burns, but is still widely used to protect third-degree (full-thickness) burns.Common side effects include itching and pain at the site of use. Other side effects include low white blood cell levels, allergic reactions, bluish grey discoloration of the skin, red blood cell breakdown, or liver inflammation. Caution should be used in those allergic to other sulfonamides. It should not be used in pregnant women who are close to delivery. It is not recommended for use in children less than two months of age.Silver sulfadiazine was discovered in the 1960s. It is on the World Health Organizations List of Essential Medicines. It is available as a generic medication. Medical uses
Tentative evidence has found other antibiotics to be more effective in the healing of superficial and partial thickness burn injuries; therefore, it is no longer generally recommended. A Cochrane review from 2013 found that most of the trials that met inclusion criteria for the review had methodological shortcomings and thus are of little use in assessing the efficacy of silver sulfadiazine in the healing of burn injuries. Another Cochrane systematic review from 2010 concluded, "There is insufficient evidence to establish whether silver-containing dressings or topical agents promote wound healing or prevent wound infection".
