External vaginal pruritus should be treated reasonably according to the cause of vulvovaginal pruritus. If it is caused by trichomonal vaginitis, it can be treated by taking metronidazole orally. During the treatment, sexual partners should be prevented from sleeping together. At the same time, they should be required to receive treatment, because trichomonal vaginitis is mainly sexually transmitted, and sexual partners should receive treatment at the same time. If the vulva itching is caused by mycotic vaginitis, the inducement should be eliminated. Local or systemic antifungal drugs should be selected according to the patient's condition. Active treatment should be given to those whose main inducement is diabetes. The broad-spectrum antibiotics, estrogen and corticosteroid hormones should be stopped in time, and underwear should be changed frequently. The used underwear, basin and towel should be scalded with boiling water, Antifungal drugs mainly include miconazole suppository, fluconazole, etc.
