If you use an insulin cartridge with cloudy-looking insulin (white
insulin suspension),
always resuspend this right before
injection.
See the Penfill® cartridge 3 ml leaflet
on how to
resuspend your type of insulin.
Make sure there is enough space in the cartridge
before you
resuspend the insulin:
The piston must be
above the white line
on the cartridge
holder when you hold the pen as illustrated. This is necessary to
allow the glass ball inside the cartridge to move freely to
resuspend the insulin.
If the piston is below the white line, replace the insulin cartridge
with a new one,
see pages 26-27.
