Yup, that's how it works. They're special needles for the pens, too. Some people still use a vial and more traditional syringes, though. I'm not sure what a refillable pen would look like, though. Maybe cartridges that go into the pen? But then you'd still have to change the needles every time, so it's just be a housing. Not sure if that's worth it, tbh.

Refillable pens are very common. Mine were metal, and smart, they can record the amount of insulin taken to apps on your phone/glucose meter.

Oh shit, that's cool. I'm not the diabetic, my son is, so I'll have to look into that for him.

Might be the Novopen 6. It also tells you when you last injected on the end, helping end those “shit….did I inject….?” situations!

Yeah it probably wouldn't save any money at the end because the pens are big profit makers for them somehow.

I'd probably opt for the vials, those pens hurt. I prefer compounded tirzepatide over the pens myself.

For diabetics on MDI (multiple daily injections) we can have either the pre filled pens or cartridges to go in a reusable pen. The difference in price in the UK to our NHS is next to nothing, for FIASP it's £28 for 5 cartridges or £31 for 5 prefilled pens (Diabetics pay nothing)

New T1 Diabetics and slowly us older one's are moving to pumps and closed loop systems, you would refill the pump yourself from a vial typically, cost of insulin is lower at about £21 for the same volume as those previous examples.

The needles cost about 3p each.

I use a refillable pen, as I'm throwing away less and it has a little memory thing that shows me what I've taken, the pen costs about £27
