I am planning to click count with a 5mg or even 7.5mg pen, and need to look at whether buying a bundle works out cheaper but I would be concerned about getting pens with short expiry dates- my first two 2.5mg pens expire in Feb 27. I’m also a bit wary of leaving a big ordering gap.
I have heard about GPs in the USA prescribing pens to last up to 12 weeks to make it cheaper for their patients and I am not worried about using pens for longer than 4 weeks.
