Vaginitis in the elderly requires the use of metronidazole and amoxicillin under the guidance of a doctor. It is recommended to use metronidazole suppositories in the vagina to inhibit the growth of bacteria in the vagina, which can promote the recovery of the disease. Estradiol valerate tablets for oral use or estradiol cream for topical use can supplement estrogen in the body, strengthen the vaginal resistance and prevent vaginal dysbiosis. Itching of the vulva can be treated with local cleansing, changing underwear regularly, and using lubricants if the vaginal dryness is severe. It is best not to use lotion to clean the vulva, and to eat more vegetables, fruits and soy products, and not to eat spicy and stimulating food.
