Metronidazole is currently divided into metronidazole tablets, metronidazole gel, and metronidazole suppositories. The usage of different types of metronidazole for gynecological diseases can vary somewhat. If a woman has acute pelvic inflammatory disease that requires the use of metronidazole, it is often given orally as a metronidazole tablet in combination with other antibiotics, such as cephalosporin antibiotics. If a woman has trichomoniasis or bacterial vaginitis, she may consider using metronidazole suppositories or metronidazole gel for vaginal insertion, each time washing the vulva with lotion and inserting the metronidazole suppositories deep into the vagina through the vaginal opening.
