Fiasp is Novo Nordisk’s newest rapid insulin. It has two additives which are supposed to speed up its abortion - nicotinamide and arginine.
I got some Fiasp a few weeks ago and wanted to give my impressions on it so far…
Before saying anything, I want to point out, my bar for insulin speed is set pretty high. I mostly have been using Apidra for injections, which is a bit faster than either of the “logs” (Humalog / NovoLog). I also frequently do intramuscular injections, and use longer needles, so I am used to more rapid insulin absorption.
I know there is a lot of excitement about it and people are hoping for a faster response.
I would just say that people should temper their expectations a little bit. It is not a game-changer. It seems perhaps a slight bit faster, but nothing that will rock your world.
I didn’t have any burning or pain from the injections like some have reported. I have only used it with syringes though, not a pump where some of the complaints have come from. And the insulin duration is the same as far as I can tell. I think getting rid of the 3-5 hour insulin lag would be the real game-changer…
So, for what it’s worth, a bit faster, that’s all. But if you want to try it, you should. From Canada, about $70 plus shipping gets a vial to your door.
