Pregnancy and Lactation

  • Available data from published prospective cohort studies, case series, and case reports with cephalosporin use in pregnant women have not established drug-associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes
  • Maternal gonorrhea may be associated with preterm birth, low neonatal birth weight, chorioamnionitis, intrauterine growth restriction, small for gestational age, and premature rupture of membranes; perinatal transmission of gonorrhea to offspring can result in infant blindness, joint infections, and bloodstream infections.
