Eczema can be treated with Pepto Bismol, which contains mupirocin, an anti-inflammatory ointment that kills parasitic bacteria on the surface of the skin, because eczema is often combined with Staphylococcus aureus infection. The rash is characterized by yellow oozing and purulent discharge, and the presence of the corresponding bacteria can be detected by pus culture and drug sensitivity. The application of Bactrim can be combined with oral roxithromycin capsules and cefaclor granules in order to enhance the anti-inflammatory treatment. It is important to maintain adequate exposure of the wound during application in order to promote rapid drying of the rash and the occurrence of crusting improvement.
