A positive test for hydrogen peroxide suggests the possibility of bacterial vaginitis, which can be treated with topical medication. Bacterial vaginitis can be treated with tinidazole suppositories or diazotide suppositories. Before using the suppositories, clean the vulva and vagina with gynecological lotions such as gynecological cleanser and bitter ginseng lotion to reduce vaginal discharge and facilitate better absorption of the suppositories. Bacterial vaginitis is treated with vaginal suppositories, usually once a day with one capsule each time, or twice a day with one capsule each time for patients with more severe symptoms, and it is best not to walk around after placing the suppositories to avoid melting them. Bacterial vaginitis is an inflammation of the vagina and vulva caused by bacterial infection, which is related to low immunity and change of pH value in the vagina.
