DIFLUCAN® (dye-FLEW-kan)

This leaflet contains important information about DIFLUCAN. It is not meant to take the place of your healthcare provider's instructions. Read this information carefully before you take DIFLUCAN. Ask your healthcare provider if you do not understand any of this information or if you want to know more about DIFLUCAN.

DIFLUCAN is a prescription medicine used to treat vaginal yeast infections caused by a yeast called Candida. DIFLUCAN helps stop too much yeast from growing in the vagina so the yeast infection goes away.
DIFLUCAN is different from other treatments for vaginal yeast infections because it is a tablet taken by mouth. DIFLUCAN is also used for other conditions. However, this leaflet is only about using DIFLUCAN for vaginal yeast infections. For information about using DIFLUCAN for other reasons, ask your healthcare provider. 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 healthcare provider 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
