For mild, uncomplicated, infections fluconazole is prescribed as a single 150 mg dose and an improvement in symptoms is usually seen within one to three days.

If a single dose does not completely relieve symptoms, or the infection is severe, fluconazole can be prescribed as three consecutive doses given three days apart. With this regimen it's expected that symptoms should improve within one to two weeks.

If symptoms continue despite appropriate treatment, fluconazole may be prescribed for every day use for ten to fourteen days, and even continued once per week for six months.

Fluconazole is an antifungal medicine and is used to treat infections caused by fungus. Fungal infections can affect any part of the body including the mouth, throat, esophagus, lungs, bladder, genital area, and the blood.

Fluconazole is also used to prevent fungal infection in people who have a weak immune system caused by cancer treatment, bone marrow transplant, or diseases such as AIDS.
