My GP has put 5 cartridges (1 box) of NovoRapid pump carts on repeat, each contains a whopping 1.6 ml.
But while on MDI I got 10 cartridges (2 boxes) of 3 ml cartridges.
I started pumping on Monday. Did a set change etc on Wednesday with the nurse, who suggested changing my cartridge every three days when I change the cannula and tubing to make things easier.
That means on average I'm using just under 5 cartridges per week, give or take.
Just tried to order more on line and it says I can't order more until 18th March! Do the GPs not look at the size of the cartridges?
I am going to ask for 20 cartridges per month on repeat, how many do you all get on repeat?
I think I am on a different pump to you - the Animas Vibe requires me to fill the pump cartridges from a vial. Each vial contains 10ml which lasts a couple of weeks.
I don't understand your logic - if you change your cartridge every 3 days, 5 cartridges should last 2 weeks.
However, like you and @Chas C my GP had no idea about what to prescribe with an insulin pump: my diabetes nurse sent a letter telling them one vial at a time was stupid (if it gets damaged, I have no backup) and the GP increased the prescription immediately.
I use 10ml Humalog vials in my Medtronic 640g. I order 3 boxes at a time and they generally last about 2 weeks per vial. I keep Humalog 3ml cartridges and 1 Lantus pen in the fridge for backup. I always take these with me if I'm away from home overnight. Last year my pump failed and had to result to both pens until a new pump arrived.
