New findings show that women who are breastfeeding can be reassured that if they take metformin for diabetes it won’t harm their baby.Metformin is excreted into breast milk, but the levels are not enough to adversely affect blood sugar levels of nursing infants, according to the findings of a small study reported in the medical journal Obstetrics & Gynecology.Gerald G. Briggs from Miller Children’s Hospital in Long Beach, California, and colleagues explain that metformin is occasionally used for controlling type 2 diabetes in nursing mothers, but the effect of metformin on the baby has been unclear.
