I know the needles are by far cheaper for my copayment $25 vs $87.5. The Vials are also cheaper than the cartridges.
I was suprised to find out that people still used the needles. I bet cost is the factor.
Are they are other reasons to use the needles vs the pens?
Trying to decide which to ask for as I have to go off the pump due to insurance and cost reasons.
