Retapamulin is indicated for use in adults and pediatric patients aged 9 months and older for the topical treatment of impetigo (up to 100 cm 2 in total area in adults or 2% total body surface area in pediatric patients aged 9 months or older) due to Staphylococcus aureus (methicillin-susceptible isolates only) or Streptococcus pyogenes. Safety in patients younger than 9 months has not been established. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Retapamulin and other antibacterial drugs, Retapamulin should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.
