Adults: Pen Preparation or Changing Cartridge
With the insulin pen in hand, start by removing the pen cap. Turn the cartridge sleeve to take it off. If the cartridge is empty, remove it. Put the new cartridge into the cartridge sleeve and push the threaded rod back completely. Then turn the cartridge sleeve to attach it to the housing.
Attach Pen Needle
Pull off the peel foil. Twist the pen needle onto the cartridge sleeve and check that it is attached correctly. Remove the outer needle protective cap, but keep it, because you will need it to remove the pen needle safely and dispose of it after use. Remove the inner needle protective cap and dispose of it.
Priming / Function Check
Dial the test dose by turning the dosage knob clockwise (not less than 2 units). For the function check, hold the pen pointing upwards and gently tap the cartridge sleeve so that the air can rise to the top. Press the push-button. A few drops of insulin must come out of the pen needle tip.
Remove pen needle after each injection
Carefully attach the outer needle protective cap on the pen needle. Twist off the pen needle and dispose of it correctly, following the advice of your physician and/or health care professional.
