To avoid injection of air and ensure proper dosing: • Dial 2 units by turning the dose selector clockwise • Hold Insulatard InnoLet with the needle pointing upwards and tap the cartridge gently with your finger a few times to make any air bubbles collect at the top of the cartridge (picture 1C) • Keeping the needle upwards, press the push-button and the dose selector returns to zero • A drop of insulin must appear at the needle tip.
