Why is this drug prescribed?
Metronidazole eliminates bacteria and other microorganisms that cause infections of the reproductive tracts and other areas.

When should it be used?
Metronidazole is usually taken three times a day for seven days. Follow the instructions on your prescription label carefully, and ask your doctor or pharmacist to explain any part that you do not understand.

How should it be used?
Metronidazole comes in tablets and injection form. Your prescription label tells you how much to take at each dose. Ask us or your pharmacist any questions you have about refilling your prescription.

What special instructions should I follow while using this drug?
If you take this medication for a genital infection, your sexual partner(s) should be treated at the same time, even if no symptoms of infection are present. (The infection may be spread to another person during sexual intercourse.) Avoid having intercourse until the infection is cured. If you do have intercourse, the male partner should wear a condom. Do not douche if you have a vaginal infection unless we tell you to do so. Wear only clean, cotton panties and pantyhose with cotton crotches until the infection is cured. Do not wear panties made of silk, nylon, Dacron, or other synthetic fabrics. These garments do not allow air to flow freely around the vagina, and so create conditions favorable to the growth of infecting organisms. Take all prescribed doses of the medication. Do not stop taking the drug even when your symptoms disappear. You must take Metronidazole for as long as prescribed or your infection may return. If your symptoms do not improve, however, or if they become worse or return after you finish the medication, contact us.

What special dietary instructions should I follow while using this drug?
Do not drink alcoholic beverages while taking Metronidazole. Alcohol may cause nausea, vomiting, abdominal cramps, headache, sweating, and flushing (redness of the face).

What should I do if I forget to take a dose?
Take the missed dose as soon as you remember it and take any remaining doses for that day at evenly spaced intervals.
