Can you take miglitol while breastfeeding?
What LactMed says
The National Library of Medicine’s own summary, quoted in full. We do not write a verdict of our own on this question, and we do not compress theirs into a label.
Limited data indicate that miglitol is poorly excreted into breastmilk. Because miglitol is also poorly absorbed orally, it is unlikely to adversely affect the breastfed infant.

Frequently asked questions
Can you take miglitol while breastfeeding?
Limited data indicate that miglitol is poorly excreted into breastmilk. The full record is quoted on this page, and the decision is one to make with the person who prescribed it — LactMed itself states it is not a substitute for professional judgement.
Does miglitol pass into breastmilk?
LactMed's measured drug levels for miglitol are quoted in full on this page, under "How much gets into breastmilk".
Do I need to pump and dump after taking miglitol?
LactMed does not frame its records that way — it reports measured drug levels in milk and what has been observed in breastfed infants, which is what this page quotes. "Pump and dump" advice for a specific drug and dose should come from your clinician or a pharmacist, not from a general rule.
