1 Mupirocin cream is for external use only. Do not get it in your eyes, nose, or mouth. If you get it in any of these areas, rinse well with cool water. 2  Use mupirocin cream with caution on skin with open wounds.  If your symptoms do not get better within 3 to 5 days or if they get worse, check with your doctor.
