FDA issued a warning this week that chronic high doses (400 mg/day to 800 mg/day) of fluconazole (Diflucan) during the first trimester of pregnancy may be associated with specific birth defects in infants. However, the risk does not appear to be associated with a single, low dose of fluconazole (150 mg), which is used to treat vaginal yeast infection (candidiasis), according to the Safety Alert released August 3.
