Erythromycin ointment can be used to treat folliculitis, which is an infectious skin disease mainly caused by the invasion of hair follicles by Staphylococcus aureus. Antibiotic ointments such as 2% tincture of iodine, mupirocin ointment, 5% neomycin ointment, and fusidic acid cream can be given for treatment. Folliculitis does not leave traces, but mainly occurs in moist and sweaty areas of the skin, such as the head, neck, upper chest, back, buttocks and vulva. It is recommended to pay attention to skin cleanliness and avoid moist and sweaty skin. If you have anemia or blood sugar abnormalities, you need to actively treat the primary disease, otherwise folliculitis is prone to recurrent attacks. For those who have more folliculitis can also be treated with systemic antibiotics as appropriate.
