Left is open pen, right is new pen. I’m away for 10 days and need to take a dose today and a dose while away. Obviously easier to take an open pen as moving around a lot.
If there are 2 doses left there’s no issue. I’ll use the open pen today and take it with me.
I could start the new pen today and take the other with me and be sure I’d have an open dose to travel with.
Thoughts please.
