Labeling two insulin pens to differentiate their contents helps ensure you administer the right type at the right time. Rapid-acting insulin works quickly to cover meals, while long-acting insulin provides a steady baseline between meals and overnight. If the pens aren’t clearly labeled, there’s a real risk of giving the wrong insulin at the wrong time, which can cause hypoglycemia after a rapid-acting dose or hyperglycemia if a basal dose is missed. Storage considerations (like refrigeration) are important, but labeling specifically supports correct timing and action rather than storage.
