Vaginitis can be treated with oral medication and vaginal medication. For trichomoniasis vaginitis and yeast vaginitis, vaginal medications are quite effective, but these types can also be treated with oral medications. If it is bacterial vaginitis, it is best to use oral medication. Vaginitis is mainly related to sexual activity, so it is essential to maintain hygiene during sexual activity. It is important to wear breathable, cotton underwear and to expose sanitary products to sunlight to reduce the occurrence of vaginitis. It is advisable to have a steady sexual partner and avoid frequent sexual activity; generally, two to three times a week is most suitable.
