When people have type 2 diabetes, their body either does not make enough insulin or does not use insulin as well as it should. Many people with type 2 diabetes need to take insulin shots. Premixed insulin combines two kinds of insulin. The first kind helps the body control blood sugar (blood glucose) all through the day. The second kind helps the body control blood sugar at meal times. There are different types of premixed insulin. This guide compares the benefits, side effects, and costs of a newer type of premixed insulin with other kinds of insulin and pills for diabetes.
