Insulin is a high risk drug which has the potential to cause serious harm if it is not used correctly.1 Until recently, all insulin available on the European market contained 100 units / mL. A high-strength insulin is one which contains insulin at a concentration of more than the standard 100 units / mL.2 These high-strength insulin products may contain, for example, 200 units / mL or 300 units / mL. There is a potential for harm if these products are not prescribed, dispensed, and administered properly.
