For women who have irritation and inflammation caused by low levels of estrogen (postmenopausal), a topical estrogen cream might be prescribed. The following are typical treatments for trichomoniasis, bacterial vaginosis, and yeast infections:

Trichomoniasis: Oral treatment with either metronidazole or tinidazole. "Sexual partner(s) should be treated simultaneously. Patients should be advised to avoid sexual intercourse for at least 1 week and until they and their partner(s) have completed treatment and follow-up." Bacterial vaginosis: The most commonly used antibiotics are metronidazole, available in both pill and gel form, and clindamycin available in both pill and cream form. Yeast infections: Local azole, in the form of ovula and cream. All agents appear to be equally effective. These anti-fungal medications, which are available in over the counter form, are generally used to treat yeast infections. Treatment may last anywhere between one, three, or seven days. Aerobic vaginitis
Treatment can include topical steroids to diminish the inflammation. Antibiotics to diminish the proportion of aerobic bacteria is still a matter of debate. The use of local antibiotics, preferably local non-absorbed and broad spectrum, covering enteric gram-positive and gram-negative aerobes, can be an option. In some cases, systemic antibiotics can be helpful, such as amoxicillin/clavulanate or moxifloxacin. Vaginal rinsing with povidone iodine can provide relief of symptoms but does not provide long-term reduction of bacterial loads. Dequalinium chloride can also be an option for treatment. In children
Vulvovaginitis in children may be "nonspecific", or caused by irritation with no known infectious cause, or infectious, caused by a pathogenic organism.
Hormonal
Hormonal vaginitis includes atrophic vaginitis usually found in postmenopausal women. Irritation/allergy
Irritant vaginitis can be caused by allergies or reactions to vaginal sprays, douches, spermicides, soaps, detergents, or fabric softeners. It can also be caused by hot tubs, abrasion, tissue, tampons, or topical medications. Foreign body vaginitis (most common foreign bodies are retained tampons or condoms) may cause extremely malodorous vaginal discharges. Treatment consists of removal, for which ring forceps may be useful. Further treatment is generally not necessary. Diagnosis
Diagnosis is typically suspected based on a womens symptoms. Diagnosis is made with microscopy (mostly by vaginal wet mount) and culture of the discharge after a careful history and physical examination have been completed. The color, consistency, acidity, and other characteristics of the discharge may be predictive of the causative agent. Determining the agent is especially important because women may have more than one infection, or have symptoms that overlap those of another infection, which dictates different treatment processes to cure the infection. For example, women often self-diagnose for yeast infections but due to the 89% misdiagnosis rate, self-diagnoses of vaginal infections are highly discouraged.Another type of vaginitis, called desquamative inflammatory vaginitis (DIV) also exists. The cause behind this type is still poorly understood. DIV corresponds to the severe forms of aerobic vaginitis. About 5 to 10% of women are affected by aerobic vaginitis.The International Statistical Classification of Diseases and Related Health Problems codes for the several causes of vaginitis are:

Prevention
Prevention of candidiasis, the most common type of vaginitis, includes using loose cotton underwear.
