What is a common treatment for impetigo?

Impetigo is a highly contagious skin infection that is most commonly caused by Staphylococcus aureus and Streptococcus pyogenes. The primary treatment for impetigo involves the use of topical antibiotics, which are effective in eradicating the bacteria causing the infection. Common topical agents include mupirocin and retapamulin, which specifically target the bacteria involved in this condition.

Topical antibiotics are preferred for localized infections, as they are easy to apply, promote faster healing, and reduce the risk of complications and transmission. In more extensive cases or in cases of systemic involvement, systemic antibiotics may also be necessary, but the immediate and first-line treatment typically begins with topical formulations.

Other options do not address the etiology and treatment of impetigo effectively. Antifungals are used for fungal infections, corticosteroids are not indicated as they can worsen infections, and cooling compresses may help alleviate discomfort but do not treat the underlying bacterial infection. Thus, topical antibiotics remain the cornerstone of impetigo management.
