WHY is this medicine prescribed?
Fluconazole is used to treat fungal infections, including yeast infections of the vagina, mouth, throat, esophagus (tube leading from the mouth to the stomach), abdomen (area between the chest and waist), lungs, blood, and other organs. Fluconazole is also used to treat meningitis (infection of the membranes covering the brain and spine) caused by fungus. Fluconazole is also used to prevent yeast infections in patients who are likely to become infected because they are being treated with chemotherapy or radiation therapy before a bone marrow transplant (replacement of unhealthy spongy tissue inside the bones with healthy tissue). Fluconazole is in a class of antifungals called triazoles. It works by slowing the growth of fungi that cause infection.
HOW should this medicine be used?
Fluconazole comes as a tablet and a suspension (liquid) to take by mouth. It is usually taken once a day, with or without food. You may need to take only one dose of fluconazole, or you may need to take fluconazole for several weeks or longer. The length of your treatment depends on your condition and on how well you respond to fluconazole. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take fluconazole exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may tell you to take a double dose of fluconazole on the first day of your treatment. Follow these directions carefully.
Shake the liquid well before each use to mix the medication evenly.
You should begin to feel better during the first few days of treatment with fluconazole. If your symptoms do not improve or get worse, call your doctor.
Continue to take fluconazole until your doctor tells you that you should stop, even if you feel better. Do not stop taking fluconazole without talking to your doctor. If you stop taking fluconazole too soon, your infection may come back after a short time.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
Are there OTHER USES for this medicine?
Fluconazole is also sometimes used to treat serious fungal infections that begin in the lungs and can spread through the body and fungal infections of the eye, prostate (a male reproductive organ), skin and nails. Fluconazole is also sometimes used to prevent fungal infections in people who are likely to become infected because they have human immunodeficiency virus (HIV) or cancer or have had a transplant operation (surgery to remove an organ and replace it with a donor or artificial organ). Talk to your doctor about the possible risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
