Diflucan
® (
fluconazole) is a prescription antifungal medication. It is approved to treat a variety of different fungal infections, such as
yeast infections and thrush. The drug can also be used to prevent
yeast infections in people undergoing bone marrow transplantations.
Who Makes This Medication?
Brand-name Diflucan is made by Pfizer, Inc. Generic versions are made by various manufacturers.
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.
When and How to Take Diflucan
Some general considerations for those taking Diflucan include the following:

The dose of Diflucan your healthcare provider recommends will vary, depending on a number of factors, including:

As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
Just like any medicine, Diflucan may cause side effects. However, not everyone who takes the drug will experience problems. Most people actually tolerate it quite well.
