How to Treat Vaginitis

Vaginitis refers to inflammation of the vagina and encompasses a group of conditions causing symptoms such as itching, burning pain, irritation, and abnormal vaginal discharge. In healthy women, the vagina possesses natural defense mechanisms against pathogen invasion, attributable to its unique anatomical and histological features. These include closure of the vaginal introitus, close apposition of the anterior and posterior vaginal walls, estrogen-stimulated proliferation and keratinization of the superficial vaginal epithelial cells, and maintenance of an acidic vaginal pH—conditions that inhibit the growth of alkaliphilic pathogens. In contrast, cervical mucus is alkaline. When these natural defenses are compromised, pathogens may more readily invade and cause vaginitis. Below, we address the question of how to treat vaginitis.

How to Treat Vaginitis

1. Bacterial Vaginosis

Patients typically present with increased vaginal discharge having a fishy odor—often exacerbated after intercourse—and may experience mild pruritus or a burning sensation in the vulva. Topical treatment options include metronidazole vaginal suppositories, administered once nightly for seven consecutive days, or mebendazole (Kemeiling) vaginal suppositories for three days. If other pathogens are identified, targeted antimicrobial therapy should be initiated; indiscriminate use of antibiotics must be avoided.

2. Trichomonas Vaginitis

When Trichomonas vaginalis proliferates extensively within the vagina, vaginal discharge increases, and patients may experience pruritus and stinging pain in the vulva. Treatment involves thorough vaginal cleansing followed by administration of vaginal suppositories. Symptoms—including stinging and itching—typically begin to subside after three to four applications; however, daily treatment must continue for approximately two weeks. Successful management requires patience and strict adherence to the full course of therapy; premature discontinuation significantly reduces the likelihood of cure.

3. Candidal Vaginitis

Candidal vaginitis is caused by infection with Candida albicans and is most common among pregnant women. Candida thrives in environments with relatively low acidity. Treatment includes antifungal vaginal suppositories (e.g., clotrimazole), combined with topical antifungal ointment applied to the vulvar area. Therapy should be continued for at least two weeks, given the high recurrence rate associated with candidal vaginitis.

4. Atrophic Vaginitis (Senile Vaginitis)

Atrophic vaginitis commonly affects postmenopausal women and is characterized by age-related vaginal changes, including epithelial atrophy, loss of rugae, and thinning and smoothing of the vaginal epithelium. The therapeutic principle is to restore estrogen levels to enhance vaginal resistance and suppress bacterial overgrowth. Options include local application of conjugated equine estrogen (Premarin) ointment twice daily, or vaginal irrigation with 1% lactic acid or 0.5% acetic acid solution once daily.

5. Pediatric Vaginitis

Pediatric vaginitis predominantly occurs in girls aged 2–9 years and is a common condition in this population. Management emphasizes maintaining external genital hygiene. Effective treatment includes vaginal and vulvar cleansing with decoctions of Sichuan pepper (Zanthoxylum bungeanum) or “Liu Yi San” (a traditional formula containing talc and licorice) diluted in water.

The above outlines approaches to treating various types of vaginitis. We hope this information proves helpful.
