Diflucan Medication Information

Diflucan® (fluconazole) is a prescription medicine licensed for the treatment of various fungal infections, such as yeast infections and thrush. It also can be used to prevent yeast infections in people undergoing bone marrow transplantations.
Diflucan belongs to a group of medications known commonly as "azole" antifungals. It works by inhibiting an enzyme that is used by fungal cells to make ergosterol, an important component of the fungal cell membrane. As a result, there is not enough ergosterol and too much of the compounds that are normally used to make it, and fungal growth is inhibited.
Before you start taking Diflucan, medication information should be reviewed with your healthcare provider to help ensure a safe treatment process. It is important to know that Diflucan can cause a number of side effects, including nausea, headaches, and abdominal pain. Since this medicine may not be suitable for everyone, it is critical that you talk to your healthcare provider before taking it if you have:
  • Liver disease, such as liver failure, hepatitis, or cirrhosis
  • Heart disease
  • An irregular heart rhythm
  • Long QT syndrome
  • An electrolyte imbalance
  • Any other allergies, including allergies to food, dyes, or preservatives.
