In the end, many factors go into choosing among the inhaled steroids, some based on known differences between the medications, some based on personal preferences. The same is true when choosing among the anti-hypertensive medications used to treat high blood pressure. Often it is necessary to try one of the medications: if it is works well, causes few or no side effects, is convenient and not excessively expensive, you are likely to continue with it. If it fails to meet one or more of these criteria, you and your doctor now have the "luxury" of other preparations to try until you find the one best for you.
Therapy with insulin is effective at lowering blood glucose in patients with diabetes, but there is resistance to its use by patients and health care providers because of its need to be injected subcutaneously and because of concern regarding interference with patients' lifestyle, risk of hypoglycemia and weight gain, and perception that people treated with insulin are "sicker" [ 1-3 ]. Consequently, patients with type 1 diabetes may hesitate to embrace multiple-dose injection regimens, while patients with type 2 diabetes may defer initiating insulin therapy, resulting in inadequate glycemic control. Therefore, less invasive options for insulin therapy are desirable.
