It looks like there are air bubbles in my SymlinPen®. What should I do?
The cartridge may contain some small air bubbles. It is normal to see small air bubbles inside the SymlinPen® cartridge. They will not harm you or affect your dose. To keep air bubbles from forming, do not store your SymlinPen® with the needle attached. Remember, always do New Pen Setup before you use a new SymlinPen® for the first time. Watch the Using the SymlinPen® video.
