    Fluconazole in pregnancy


    High-dose animal studies have revealed evidence of embryolethality, fetotoxicity, and teratogenicity. Several epidemiologic studies do not indicate an increased risk of congenital anomalies associated with low-dose exposure during pregnancy (most patients received a single 150 mg oral dose). Data from several hundred pregnant women treated with standard doses (less than 200 mg/day), as a single or repeated dose in the first trimester, show no adverse fetal effects. A few cases of a distinctive and rare pattern of birth defects have been reported in infants exposed in utero to high-dose maternal fluconazole (400 to 800 mg/day) during most or all of the first trimester. Brachycephaly, abnormal facies, abnormal calvarial development, cleft palate, femoral bowing, thin ribs and long bones, arthrogryposis, and congenital heart disease have been observed in these infants. These effects are similar to those observed in animal studies. A malformed infant girl was born prematurely to a woman who received 400 mg/day throughout pregnancy for disseminated coccidioidomycosis. The infant displayed cranioschisis of the frontal bones, craniostenosis of the sagittal suture, hypoplasia of the nasal bones, cleft palate, humoral-radial fusion, bowed tibia and femur, bilateral femoral fractures, contractures of both upper and lower extremities, and defects of the fingers and toes. Two additional cases of congenital malformations were reported in infants born to women receiving this drug during or beyond the first trimester of pregnancy. Citing new evidence pointing to an increased risk of miscarriage, the FDA is currently reviewing the safety of oral fluconazole (Diflucan) as a vaginal yeast infection treatment in pregnant women. A Danish study recently found that pregnant women who took more than one 400-800 mg dose of oral fluconazole (considered a high dose) reported an unexpectedly high rate of birth abnormalities. Current FDA labeling does not address extended use, only indicating that a single dose of 150 mg taken during pregnancy to treat a vaginal yeast infection does not increase risk of birth abnormalities or other problems during pregnancy. In fact, most of the women in the Danish study took only one or two 150 mg doses of oral fluconazole, and the authors cautioned that their sensitivity analysis comparing lower and higher doses of the drug was only based on seven stillbirths. Risks associated with fluconazole and pregnant women are not new to the FDA, as the agency has previously classified the drug in pregnancy class D, meaning that there is evidence of risk to the fetus, but it may be used if the mother's condition is serious or life-threatening. This Danish team has been studying the safety of fluconazole in pregnancy for several years -- finding no significant risk of congenital malformations associated with use of the drug in pregnant patients in 2013. In announcing the safety review, the FDA recommended "cautious prescribing" of oral fluconazole to pregnant patients with yeast infections, at least until the review is complete.

Advice and warnings for the use of Fluconazole Diflucan during pregnancy.

    The Food and Drug Administration said Tuesday that doctors should exercise caution in prescribing to pregnant women an oral drug for yeast infections because of new evidence suggesting a possible link to miscarriage. had previously warned that chronic high doses of the drug, fluconazole (brand name Diflucan), might be linked to “a rare and distinct set of birth defects” in infants whose mothers took it in the first trimester. An estimated 10 percent of women get yeast infections in pregnancy, a period during which they are especially susceptible. Those doses ranged from 400 to 800 milligrams a day in several case reports. Symptoms include severe itchiness, painful sex and abnormal vaginal discharge. Pregnant women in a recent Danish study, however, mostly took one or two doses of fluconazole, each just 150 milligrams, a dose that the agency did not consider a problem until now. The study, conducted by researchers at the State Serum Institute in Copenhagen, was published in January in JAMA. The study, a review of medical records, included more than 1.4 million pregnancies over a 17-year span in Denmark. Among the roughly 3,300 women who took fluconazole seven to 22 weeks into pregnancy, about 150 miscarried, compared with roughly 560 of 13,000 women matched for maternal age and gestational age. A.’s review is complete and more is understood about this study and other available data, we advise cautious prescribing of oral fluconazole in pregnancy,” she said in an email message. Women who used the drug in the first 22 weeks of pregnancy had a significantly higher chance of miscarriage than those who did not. A., said it was uncertain when the agency would issue further recommendations. The Centers for Disease Control and Prevention recommends that only topical azole products be used to treat yeast infections in pregnancy, even for recurrent infections.

    Connor Travelers’ diarrhea (TD) is the most predictable travel-related illness. Attack rates range from 30% to 70% of travelers, depending on the destination and season of travel. Traditionally, it was thought that TD could be prevented by following simple recommendations such as “boil it, cook it, peel it, or forget it,” but studies have found that people who follow these rules may still become ill. Poor hygiene practice in local restaurants is likely the largest contributor to the risk for TD. TD is a clinical syndrome that can result from a variety of intestinal pathogens. Bacterial pathogens are the predominant risk, thought to account for up to 80%–90% of TD. Intestinal viruses usually account for at least 5%–8% of illnesses, although improved diagnostics may increase recognition of norovirus infections in the future.
