Fluconazole Tablets USP
This leaflet contains important information about fluconazole (floo-KON-a-zole). It is not meant to take the place of your doctor's instructions. Read this information carefully before you take fluconazole. Ask your doctor or pharmacist if you do not understand any of this information or if you want to know more about fluconazole.
What Is Fluconazole?
Fluconazole is a tablet you swallow to treat vaginal yeast infections caused by a yeast called Candida. Fluconazole helps stop too much yeast from growing in the vagina so the yeast infection goes away. Fluconazole is different from other treatments for vaginal yeast infections because it is a tablet taken by mouth. Fluconazole is also used for other conditions. However, this leaflet is only about using fluconazole for vaginal yeast infections. For information about using fluconazole for other reasons, ask your doctor or pharmacist. See the section of this leaflet for information about vaginal yeast infections.
What Is a Vaginal Yeast Infection?
It is normal for a certain amount of yeast to be found in the vagina. Sometimes too much yeast starts to grow in the vagina and this can cause a yeast infection. Vaginal yeast infections are common. About three out of every four adult women will have at least one vaginal yeast infection during their life.
Some medicines and medical conditions can increase your chance of getting a yeast infection. If you are pregnant, have diabetes, use birth control pills, or take antibiotics you may get yeast infections more often than other women. Personal hygiene and certain types of clothing may increase your chances of getting a yeast infection. Ask your doctor for tips on what you can do to help prevent vaginal yeast infections.
If you get a vaginal yeast infection, you may have any of the following symptoms:
- a burning feeling when you urinate
- a thick white vaginal discharge that looks like cottage cheese

Fluconazole keeps working for several days to treat the infection. Generally the symptoms start to go away after 24 hours. However, it may take several days for your symptoms to go away completely. If there is no change in your symptoms after a few days, call your doctor.
