The walgreens website says you need a scrip for the pen, but when my father went and spoke to the walgreens folk, they said they'd order it without a scrip, without insulin, and that it'll be here tomorrow.
I need another pen because I want to use up my pen supplies and because I'm low on syringes. I find the pen more comfortable when injecting my legs and stomache, but less comfortable for my arms; I think it's the weight. I think it would be really cool if someone had weights designed to go on syringes.
I also like the Novopen Jr because a half unit makes a significant difference for me, especially in corrections. Dosing to the half unit with a syringe is difficult.
And the final point in favor of the Novopen is that I don't ever want to get confused and inject the wrong insulin. That's how dead in bed happens.
