Hi i have just started injecting Victoza, and I am unsure about storage. Do you store un-used pens and once you use for the first time, do you need to store it back in the fridge or is it okay stored in a cupboard?
In my understanding, you should store unused pens in a refridgerator. Once you have started using a pen, it is okay to store it at room temperature for a max of 30 days, providing it does not get too hot!
Have a read of this page, also has some numbers for help;-
