Hi, I advice you against any such self medications for diabetes. And also avoid such abrupt stopping of antidiabetic medications in the future. Diabetes is a chronic condition that requires long term medication. You need to take the medications as prescribed. Getting off on an antidiabetic drug is extremely rare. The dose and medications depends upon your blood glucose control. For now, I suggest you against using your husband s insulin. You need to get yourself evaluated by an endocrinologist or a physician. As you are insulin naive, it s difficult to predict the effectiveness of insulin dose. And the metformin in your system can exaggerate insulin action. Please do follow the prescription as suggested by your doctor. Medications will be based on blood glucose levels and glycemic control. You will also be advised to get HbA1C values that predicts your average glycemic control over few weeks as you are not compliant with medications. I hope the above information helps you. Thanks for writing into healthcaremagic. Take care.
