If diabetes is not controlled alone by insulin, Glycomet can be taken during pregnancy along with insulin. High blood sugar during is known to cause fetal congenital malformation.

In such condition, Glycomet is recommended along with insulin during pregnancy. So continue taking insulin and Glycomet. This is safe for your baby. Uncontrolled diabetes will cause more harm to your baby. Thanks
