Janumet XR is a combination prescription drug with different drug classes that help lower blood sugar in type 2 diabetes patients.

Sitagliptin = Dipeptdl Peptidase - 4 Inhibitor

Metformin = Biguanides

Used with caution during breastfeeding

We don't know what sitagliptin does to breast milk or the long-term effects a breastfed infant may have. We do know that it was present in milk from rats.

The benefits of breastfeeding must be compared to the risks of the effects of the medication. Uncontrolled blood sugar is also a risk, insulin therapy may be necessary.

Unknown effects on the fetus, another alternative for controlling blood sugar should be discussed if diet and exercise aren't working.
