Mupirocin ointment, also known by its trade name Bactrim, can be applied to the vulva clinically, and can be used when there are local boils, inflammation of hair follicles, or eczema of the vulva combined with infection. However, if you are allergic to Pepto-Bismol, you should not apply it, and you can use other medications for treatment. It is also recommended that you go to the hospital to have your vulva examined for a preliminary diagnosis before using Pepto-Bismol for treatment under the guidance of a doctor if you feel uncomfortable. In addition, it is also recommended to wear loose pants in daily life to avoid poor pelvic blood circulation due to tight underwear or outer pants, which can cause acute inflammation in the vulva, resulting in pain or redness.
