Medications, With or Without Insulin ( Diabetes )
Oral medications are not the same as insulin These medicines help your pancreas release more insulin or help your own body’s insulin work more efficiently to lower your blood glucose. Therefore, your pancreas must still make and release insulin in order for these medications to work. (There are exceptions. Metformin, pioglitazone, or rosiglitazone all work well with injected insulin).
If you have type 2 diabetes, keep in mind that you may eventually need to inject insulin, even if you’re using oral medications now. Over time, some people with type 2 diabetes are no longer able to produce any insulin from their own pancreas and must be treated with insulin injections.
