What Is Regular Insulin?
Regular insulin (Humulin® R, Novolin® R) is the most basic form of insulin used to treat diabetes. It is called “regular” insulin because it is identical to insulin made by the human body. It is a short-acting insulin used to help control the spike in blood sugar that occurs with meals. It is typically used in combination with a long-acting insulin. Regular insulin can also be used in an insulin pump, although newer, rapid-acting insulins are usually preferred for pump use.
