Is it safe to use DiaBeta if I am breastfeeding?

Doctors don’t know if it's safe to use the diabetes drug DiaBeta (glyburide) while you're breastfeeding, so it may be wise to switch medications unless you have a compelling reason to stick with DiaBeta.

Experts don't know if DiaBeta passes into breast milk, but similar medications (a class called sulfonylureas) do. Because the medication may trigger low blood sugar in nursing babies, your doctor may suggest you discontinue either DiaBeta or nursing. If you choose to keep breastfeeding, you may be advised to switch from DiaBeta to insulin.
