Cefcamate Pivoxil Hydrochloride

Cefcapene pivoxil hydrochloride is an antibiotic often used by women who are or may be pregnant. However, the safety of exposure to it during the first trimester of pregnancy has not been assessed. In this study, we aimed to clarify the effects of exposure during the first trimester of pregnancy on maternal and fetal outcomes. Data were obtained from pregnant women who were counseled on drug use during pregnancy at two Japanese facilities from April 1988 to December 2017. The incidence of major malformations in singleton pregnancy was compared between neonates born to women who took cefcapene pivoxil hydrochloride (n = 270) and control drugs (n = 1594) during their first trimester. The adjusted odds ratio of the incidence of major malformations was calculated using multivariate logistic regression analysis adjusted for smoking during pregnancy and maternal age. The incidence of major malformations was 2.6% in the cefcapene pivoxil hydrochloride group and 1.8% in the control group. There were no significant differences in the incidence between the cefcapene pivoxil hydrochloride and control groups (adjusted odds ratio: 1.48 [95% confidence interval: 0.64-3.42], p = 0.36). This prospective cohort study showed that exposure to cefcapene pivoxil hydrochloride during the first trimester of pregnancy was not associated with increased risk of major malformations in infants. Our findings will help healthcare providers in choosing appropriate medicines.
