Can tablets be taken for diabetes be taken during pregnancy?

No: At present no oral medications are felt to be 100% safe in pregnancy but their are some new studies to support the use of one or two classes of oral medications but i would discuss the risk versus benefit of such with your ob.

Yes: Metformin appears to be safe in pregnancy, but not everyone agrees with its use, traditionally, diabetes in pregnancy has been treated with insulin.

Yes: One large prospective trial showed that a sulfonylurea pill for gestational diabetes didn't cross the placenta and controlled sugars (used after 11 weeks gestation). The am coll of ob/gyn doesn't fully endorse it, so most physicians use insulin. Data on metformin is retrospective, so i agree with the other respondent that a discussion of these issues with your physician is very important.

Yes: Dont forget to get a dilated eye exam by a physician. Diabetic retinopathy can get worse during the pregnancy. At the very least, try to get 1-2 exams before delivery and another after delivery.
