Can you take sitagliptin 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.
No information is available on the clinical use of sitagliptin during breastfeeding. Sitagliptin has a shorter half-life than most other dipeptidyl-peptidase IV inhibitors, so it might be a better choice among drugs in this class for nursing mothers. Monitoring of the breastfed infant's blood glucose is advisable during maternal therapy with sitagliptin. However, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.

Frequently asked questions
Can you take sitagliptin while breastfeeding?
No information is available on the clinical use of sitagliptin during breastfeeding. 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 sitagliptin pass into breastmilk?
LactMed's measured drug levels for sitagliptin are quoted in full on this page, under "How much gets into breastmilk".
Do I need to pump and dump after taking sitagliptin?
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.
