Objective:
The aim of this study was to determine the impact of initial glyburide dosing on pregnancy outcomes. STUDY DESign: Retrospective cohort of singleton pregnancies complicated by gestational diabetes mellitus (GDM) from 2007 to 2013. Women who received glyburide were compared by initial dose: 2.5 mg (n = 170) versus 5 mg (n = 154) total daily dose. The primary maternal outcome was hypoglycemia, defined as a blood glucose < 60 mg/dL. The primary neonatal outcome was birth weight. Secondary maternal outcomes included time to blood glucose control, preeclampsia, and cesarean delivery. Secondary neonatal outcomes included macrosomia (>4,000 g), hypoglycemia (<40 mg/dL), shoulder dystocia, and preterm delivery.
Results:
The 5 mg/day glyburide dose did not increase maternal hypoglycemia (26% in the 2.5 mg/day group vs. 27% in the 5 mg/day group; adjusted odds ratio [AOR] 0.67; confidence interval [CI] 0.30-1.49). An increase in macrosomia in the 5 mg/day group was not significant after adjusting for maternal obesity (AOR 2.16; CI 0.96-4.88). Differences in preterm birth and large for gestational age were not significant after adjusting for prior preterm birth and maternal obesity, respectively.
Conclusions:
A higher starting dose of glyburide for the management of GDM was not associated with increased maternal hypoglycemia or decreased adverse neonatal outcomes.
