In this session, we will be discussing the consumer medication information for fluconazole, trade name DiflucanTM.

What it’s for & How to take

Fluconazole is an antifungal medication that works to slow the growth of certain types of fungus. This medication may be used to prevent and treat fungal infections throughout the body, including vaginal, oral, throat, abdominal, blood and other organs that may be infected.

In general, our body keeps a steady balance of healthy fungus and bacteria. The balance might be changed by antibiotics, steroids, chemotherapy or other situations that stress your body. When this happens, fungus grows easier in your body.

Depending on the type of your infection, your doctor may give you a single oral dose to be taken one time only, or have you take this medication daily for 1-2 weeks or even longer.

Fluconazole may be taken with or without food. If you are taking a daily dose of this medication take it at the same time each day. If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.

Take this medication until it is all done, even if you are feeling better and the symptoms are gone. Stopping the medication too soon may allow for the fungus to come back only after a short time. If you notice that your symptoms are not getting better, call your doctor.

Warnings & Cautions

  • Tell your doctor if you have ever been told you have any heart rhythm problems. Rarely, fluconazole may cause your heart to beat fast and unsteady. If you feel any severe dizziness or feel like your heart is racing or beating too fast, get medical help right away.
  • Rarely, this medication may make you dizzy, drowsy, or blur your vision. Do not drive or do any activity that requires focus and attention until you are sure you can do them safely. Avoid alcoholic beverages while taking fluconazole.
  • Infants born to mothers who are taking fluconazole may be at risk. This medication should only be used during pregnancy when the benefit to the mother is greater than the risk to the unborn baby. Talk with your doctor about this.
  • Fluconazole passes into breast milk. Talk with your doctor before breastfeeding if you are taking this medication.

Interactions & Side Effects

  • Tell your pharmacist or doctor all your medication allergies so they may determine if fluconazole is safe for you to take.
  • Avoid dangerous drug interactions. Tell your pharmacist or doctor all the other medication you are taking, including over the counter supplements, even if you don’t take them very often.
