Indications 

Diflucan is an oral antifungal medication that is indicated for the treatment of fungal infections throughout the body, such as those affecting the mouth, throat, gastrointestinal system, respiratory system, bladder, and genitals.  

Individuals who have a history of cancer may be at an increased risk of developing fungal infections and may, therefore, be more susceptible to these infections. 

Uses and Dosage 

Take Diflucan as directed by your doctor. Follow all instructions on your prescription label, and read all medication guides or instructions carefully. 

Your dosage will depend on the type of infection being treated. For vaginal infections, a single pill may be sufficient, while other infections may require a double dose for the first treatment. Follow your doctor’s instructions closely. 

Diflucan can be taken with or without food. 

Important to complete the full course of treatment as prescribed, even if your symptoms improve quickly. Skipping doses can increase your risk of developing medication-resistant infections. Note that fluconazole will not treat viral infections such as the flu or a common cold.
