Metronidazole Vaginal

Name: Metronidazole Vaginal

Why is this medication prescribed?

Metronidazole is used to treat vaginal infections such as bacterial vaginosis (an infection caused from too much of certain bacteria in the vagina). Metronidazole is in a class of medications called nitroimidazole antimicrobials. It works by stopping the growth of bacteria.

How should this medicine be used?

Metronidazole comes as a gel to be used in the vagina. Metronidazole is usually used as a single dose at bedtime (Nuvessa) or once daily for 5 consecutive days at bedtime (MetroGel Vaginal, Vandazole). Metronidazole is also used twice daily for 5 days (MetroGel Vaginal). Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use metronidazole exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Be careful not to get metronidazole gel in your eyes, mouth, or on your skin. If you do get it in your eyes, wash them with cool water and contact your doctor.

Do not have vaginal intercourse or use other vaginal products (such as tampons or douches) during your treatment with the vaginal gel.

Metronidazole gel for the vagina comes with a special applicator. Read the instructions provided with it and follow these steps:

  1. Fill the special applicator that comes with the gel to the level indicated.
  2. Lie on your back with your knees drawn upward and spread apart.
  3. Gently insert the applicator into your vagina and push the plunger to release all of the medication.
  4. Withdraw the applicator and dispose of it properly. If you are instructed to reuse the applicator, wash it with soap and warm water.
  5. Wash your hands promptly to avoid spreading the infection.
