A review recommends the following for managing iron deficiency in pregnant women and neonates: Screen all pregnant women for iron deficiency at their first prenatal visit, regardless of hemoglobin levels. Administer iron supplements to pregnant women with iron deficiency, with or without anemia. During the first trimester, prescribe oral iron, avoiding intravenous iron due to limited safety data.
