Diflucan capsules, suspension and infusion all contain the active ingredient fluconazole, which is a type of drug called a triazole antifungal. Fluconazole is available without a brand name, ie as the generic drug. Fluconazole is prescribed to treat infections with fungi and yeasts.
Diflucan is prescribed to treat a number of different types of fungal and yeast infections, particularly those caused by Candida or Cryptococcus species of fungi.
Diflucan is prescribed to treat fungal infections called candidiasis (also known as thrush or yeast infections). These include vaginal infections, throat infections, and fungal infections elsewhere in the body, such as infections of the urinary tract, peritonitis (inflammation of the lining of the abdomen), and pneumonia. Diflucan is prescribed to guard against candidiasis in some people receiving bone marrow transplants, and is prescribed to treat meningitis (brain or spinal cord inflammation) caused by another type of fungus.
Diflucan kills the fungi that are causing an infection by interfering with their cell membranes. It works by stopping the fungi from producing a substance called ergosterol, which is an essential component of fungal cell membranes. The disruption in production of ergosterol causes holes to appear in the fungal cell membrane.
In addition, Diflucan is now being prescribed for fungal infections in kidney and liver transplant patients, and fungal infections in patients with AIDS.
It can be taken by mouth or may be administered via a drip into a vein depending on the type and severity of the infection. The length of treatment will depend on the type and severity of the infection, for example vaginal thrush can normally treated with a single dose by mouth, while some other infections may require six to eight weeks of treatment.
The cell membranes of fungi are vital for their survival. They keep unwanted substances from entering the cells and stop the contents of the cells from leaking out. As fluconazole causes holes to appear in the cell membranes, essential constituents of the fungal cells can leak out. This kills the fungi and treats the infection.

Diflucan is prescribed for the treatment of:
- Candida infections of the linings of the mouth, throat, lungs or urinary tract;
- Fungal infections caused by cryptococcus fungi, including cryptococcal meningitis and infections affecting the lungs or skin;
- Fungal skin infections, such as athlete's foot , ringworm, jock itch, pityriasis versicolor, or candida skin infections;
- Inflammation of the penis and/or foreskin caused by infection with candida albicans;
- Inflammation of the vagina caused by infection with candida albicans;
- Internal fungal infections caused by candida, eg infections of the bloodstream, urinary tract, heart, lungs, abdomen or other widespread internal infections;
- Preventing fungal infections in people with a weakened immune system and low white blood cell counts, for example due to chemotherapy, radiotherapy or bone marrow transplants;
- Preventing relapse of disease caused by cryptococcus fungi, eg cryptococcal meningitis, in people with aids;

For yeast infections of the esophagus

Cadidiasis in the upper digestive canal is usually treated with a dose of 6 mg per 2.2 pounds of body weight on the first day, and half that amount once daily thereafter.
Daily doses of up to 12 mg per 2.2 pounds of body weight are sometimes prescribed.


For vaginal infections

The usual treatment is a single 150-mg dose.

For throat infections
