If the examination of vaginal secretions clearly indicates trichomonal vaginitis, treatment must specifically target trichomoniasis using drugs such as metronidazole, tinidazole, or ornidazole. Trichomonal vaginitis requires simultaneous treatment of both partners; treating only the woman is inadequate. It is also necessary for both partners to sterilize or sun-dry their underwear or bed sheets, as failing to do so can lead to easy recurrence. Therefore, detecting trichomonal vaginitis cannot be solely treated with medication applied inside the vagina.
