Fluconazole (Page 8 of 9)

Dosage In Patients With Impaired Renal Function:

Fluconazole is cleared primarily by renal excretion as unchanged drug. There is no need to adjust single dose therapy for vaginal candidiasis because of impaired renal function. In patients with impaired renal function who will receive multiple doses of fluconazole, an initial loading dose of 50 to 400 mg should be given. After the loading dose, the daily dose (according to indication) should be based on the following table:

Creatinine Clearance (mL/min) Percent of Recommended Dose
> 50 100%
≤ 50 (no dialysis) 50%
Regular dialysis 100% after each dialysis

These are suggested dose adjustments based on pharmacokinetics following administration of multiple doses. Further adjustment may be needed depending upon clinical condition.

When serum creatinine is the only measure of renal function available, the following formula (based on sex, weight, and age of the patient) should be used to estimate the creatinine clearance in adults:


Weight (kg) x (140-age)
72 x serum creatinine (mg/100 mL)


0.85 x above value

Although the pharmacokinetics of fluconazole has not been studied in children with renal insufficiency, dosage reduction in children with renal insufficiency should parallel that recommended for adults. The following formula may be used to estimate creatinine clearance in children:

K x linear length or height (cm)
serum creatinine (mg/100 mL)

(Where K = 0.55 for children older than 1 year and 0.45 for infants.)


Fluconazole may be administered orally.

Rx Only

This leaflet contains important information about fluconazole. 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:

  • itching
  • a burning feeling when you urinate
  • redness
  • soreness
  • a thick white vaginal discharge that looks like cottage cheese

What To Tell Your Doctor Before You Start Fluconazole?

  • diabetes medicines you take by mouth such as glyburide, tolbutamide, glipizide
  • blood thinners such as warfarin
  • cyclosporine (used to prevent rejection of organ transplants)
  • rifampin or rifabutin (used for tuberculosis)

  • phenytoin (used for seizures)
  • theophylline (used for asthma)
  • cisapride (Propulsid®† ; used for stomach acid problems)
  • terfenadine (Seldane®‡ ; used for allergies)
