Oral hypoglycaemic agents during pregnancy: The evidence for effectiveness and safety

With the increase in obesity and sedentary lifestyles, the incidence of diabetes among reproductive-aged women is rising globally. Providers are expected to care for a growing number of women with gestational diabetes (GDM) in the coming decades. Traditionally, insulin has been considered the standard for management of GDM, when diet and exercise fail to achieve tight maternal glucose control without the risk of transfer of insulin across the placenta. Understanding the effectiveness and safety of the use of oral diabetes agents during pregnancy for both maternal and neonatal outcomes as an alternative management option is essential to the care of women with GDM and their offspring. In this review, our objectives were to (1) summarise the available evidence on the efficacy these medications, (2) review available data on adverse effect, (3) discuss current gaps in research, outlining limitations in current study designs that deserve attention and (4) summarise key points for the practicing clinician.
