3.The injection way of insulin pen
Check for adequate insulin before each injection, and then rotate the dose adjustment knob to the number of units needed. If the insulin injected is a suspension, the insulin pen should be turned upside down for about 1O times, until the solution becomes a uniform white suspension, in case the concentration of the liquid is not uniform, resulting in poor blood glucose control. Instant, short-acting and insulin glargine are clear solutions that can be injected directly.
