If you went on the pump..
You have to fill up the pump cartridges from the old fashioned insulin vial (about 3 cartridges from one vial) this will be added to your prescription, you have to keep spare background and quick acting insulin cartridges + pens in case of emergency, such as pump failure.. This this part of your prescription will stay as normal, insulin and test strips via your gp..
The pump consumables, cartridges, service packs, infusion sets aren't available on normal prescription, this will be dependant on how your clinic arrangements but it either of two ways..
You clinic
Will set up an account with the pump company so you can order directly from the company, most clinics will ask you to order 3 months supply at a time (keeps delivery costs down)
or
Some clinic's arrange for their pumpers to order/pick up their supplies direct from the hospita clinic..
If you are suceesful with getting an insulin pump, your clinic will inform you about the arrangements they have concerning the consumables side of it..
Again if you are succesful most pump manufactors will supply one or two pump cases with the pump as part of the package, but carry a array of different case/pouches, strips for wearing the pump, you can order these direct from the manufacturer but you have to bare the cost of this..
