I’m trying to experiment with using refillable pens rather than syringes to cut down on waste, and I managed to get my hands on some Novolin R penfills (as I mainly use R for bolus). Unfortunately, I couldn’t find NovoEcho Pens anywhere, and settled with buying Lilly Luxura HD Pens instead because I could find them at an affordable price.
Question now is, will the penfills I have work in this pen? Or are they just too different? Does anybody else have any experience with this? I’d love to know if I can and, if not, if there’s a way to make them fit.
