it's hard to say. maybe, maybe not. it may still be good and bear may just need a higher dose. (worked up systematically, of course).
some ppl can stretch out their pens or cartridges for longer than a month. but we like to swap out at 4-6 weeks (we used lantus cartridges before we switched to levemir pens). then again we're paranoid ppl :razz:
i personally think it would be a good idea to have a rx for pen cartridges in hand. unless bear is a high dose kitty, cartridges will end up being cheaper because you won't be tossing 150 mls of insulin out all at once - only the 30 ml cartridge that's open. whereas, with a vial, when you toss it, that's 100 mls (less what you've used) down the drain.
