THURSDAY, June 14, 2018 (HealthDay News) -- Fluconazole use in pregnancy seems not to be associated with significantly increased risks of stillbirth or neonatal death, according to a research letter published in the June 12 issue of the Journal of the American Medical Association.
Björn Pasternak, M.D., Ph.D., from the Karolinska Institutet in Stockholm, and colleagues examined whether fluconazole use during pregnancy is associated with stillbirth and neonatal death. The authors used nationwide register data to identify all pregnancies with singleton live births and stillbirths in Sweden and Norway. A total of 10,669 exposed and 106,690 unexposed pregnancies from a cohort of 1,485,316 pregnancies were included in the matched analysis of stillbirth, and 10,640 exposed and 106,387 unexposed pregnancies were included in the matched analysis of neonatal death.
The researchers found that there were 2.7 and 3.6 stillbirths per 1,000 exposed and unexposed pregnancies, respectively (hazard ratio, 0.76; 95 percent confidence interval, 0.52 to 1.1) and 1.2 and 1.7 neonatal deaths per 1,000 exposed and unexposed pregnancies, respectively (risk ratio, 0.73; 95 percent confidence interval, 0.42 to 1.29). Similar results were seen for doses of 300 mg or less and more than 300 mg.
"Although the data on fluconazole use in pregnancy suggest no increased risk of stillbirth, additional studies should be conducted and the collective body of data scrutinized by drug authorities before recommendations to guide clinical decision making are made, and weighed against the benefits of therapy," the authors write.
