Managing diabetes: patients should not change their insulin delivery device without checking with their healthcare specialist

If patients are contacted directly by a manufacturer or other organisation to try using a different insulin therapy system they should first discuss this with their diabetes specialist to avoid risk of hyperglycaemia, hypoglycaemia or diabetic ketoacidosis.


Healthcare professionals are requested to have systems in place to remind their diabetic patients:

  • to use devices that have been recommended or prescribed for them by their diabetes specialist

  • not to stop or change their prescribed insulin management regimen without seeking the advice of their diabetes specialist

  • to contact their diabetes specialist if they are invited by a manufacturer to trial a new device e.g. via social media
