How much insulin do you get in the pump?

I'm very insulin dependend. I'm considering changing to the pump but I take 2u for 10g of carbs with lunch. About 48 units a day.I was wondering how much insulin you can get in the pump. Cause I like to eat alot :)

The Medtronic 5 series hold 180U and the 7 series hold 300U. I'm not sure about the other models. I had the 722 first, as the doc wasn't sure that the 180U would quite be enough but I generally run c. 35-50U/ day. When the warranty ran and it was time for a new one, I got the 523 which has been fine. One advantage to sizing it "correctly" is that the scaling of the amount in the pump on the little icon thing was not useful in the bigger one. There's still a way to scroll to the screen to check but the icon was always on one bar of insulin left, even w/ 100U on the bigger model. I like the smaller one in general and for running because it's not quite as big as the 700 series. I would think you'd be fine with a 523. The other thing that may happen is that pumped insulin seems to work a bit "hotter" so you might find you'd need a bit less with a pump? I think the Pods and Animas models hold around 200U so those should be fine too, although one thing about the pod is that you can end up tossing "leftovers" if you don't use them. I run mine pretty dry before I swap it out most of the time, just waiting until I have a unit or two left quite a bit.

the Accu-chek Spirit holds 315 units.

I use an Animas Ping which fits 200u in the cartridge (really more like 160u once I fill tubing and everything). I use more insulin each day than you do, and a cartridge lasts me 2-3 days, depending on how much I eat.

Hi Fiona, Omnipod holds 200 units.

I use a Medtronic 723 because of the larger 300 unit reservoir. I'm T2 and we tend to use more insulin. My daily amount on pens was 60 to 75 units a day. I have found that since I started pumping it has fallen to less that 50 a day and realize now that I could get by with the 180 units that the 523 holds. Most but not all find they use less insulin when using a pump.

Ok thanks everyone. Very helpful
