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.
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.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Do not freeze or refrigerate it.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( Web Site) for more information if you do not have access to a take-back program.
Keep all appointments with your doctor.
Before having any laboratory test, tell your doctor and the laboratory personnel that you are using metronidazole.
Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription. If you still have symptoms of infection after you finish the metronidazole, call your doctor.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
