Insulin

Insulin concentrations

• The most widely available insulin concentration is 100 IU/ml (U 100)
• Treatment with U 40 (40 IU/ml) or other concentrations such as U 500 are also acceptable subject to availability and special needs
• Care must be taken to ensure that the same concentration is supplied each time a new prescription is made
• Very young children occasionally require insulin diluted with diluent obtained from the manufacturer, but special care is needed in dilution and drawing up the insulin into the syringe
