Is 40 IU/ml and 100 IU/ml the same in huminsulin 30/70?
IU/ml stands for International Units per milliliter. Insulin is available in two strengths: s 40 IU/ml, which means that each milliliter contains 40 units of insulin and 100 IU/ml, which means that each milliliter contains 100 units of insulin. You can see that an insulin containing 100 units per milliliter is more concentrated than one containing 40 units per milliliter. In the U.S. most insulin comes in a concentration of 100 units per millimeter. There is also a very concentrated type of regular insulin called U500 insulin, which has 500 units of insulin per millimeter. Some countries continue to manufacture 40 IU/ml insulin, but most have switched over to 100 IU/ml, often referred to as “U-100” insulin. Humulin or Novolin 70/30 insulin are mixed insulins and the 70/30 refers to the percentage of short-acting vs. longer- acting insulin. For instance, Humulin 70/30 insulin consists of 70% NPH insulin and 30% regular insulin.
