Can You Use Mupirocin on an Open Wound?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 22nd, 2026.
Yes, mupirocin can be used on open wounds when prescribed by a healthcare provider. This topical antibiotic is specifically designed to treat bacterial skin infections and prevent infection in minor cuts, scrapes, and surgical incisions. Mupirocin works by inhibiting bacterial protein synthesis, making it effective against common wound pathogens like Staphylococcus aureus and Streptococcus pyogenes. Studies show it reduces infection rates by up to 85% when applied to clean wounds. However, proper wound cleaning and assessment are essential before application. You should only use mupirocin on open wounds under medical supervision, as inappropriate use can lead to antibiotic resistance or delayed healing.
