We just ordered some FIASP cartridges, but the pharmacist could not tell us which pen they fit. I am assuming that they fit any Novolog pen, since both are made by Novo, and since they are both short acting. Does anyone have experience with that? ---

The Novo pens are designed to fit any of the Novo cartridges. The backup pen I carry with me everywhere is an Echo with Fiasp. ๐Ÿ™‚ ---

All cartridges from the same company are usually the same (e.g., Novo Nordisk has their NovoTwist pen needles that fit their pens/cartridges). Itโ€™s pens and cartridges from different companies (e.g., trying to use an Echo pen with a Humalog cartridge) that wonโ€™t work. ---

Jen is right. all novo nordisk insulins (fiasp, levemir, novorapid, novolog) fit in the Novopen Echo or the other one I have (Novopen 4 I think). I use BD pen needles on my novolog pens. I think the pen needles are pretty interchangeable as I use the same needlea on the Novopens and the Humalog pens. ---

Glad to see confirmation! I can also confirm that our pen needles work on all sorts of insulin pens, including Humalog, Novolog and Lantus pens. ---

> [@Aaron](#): > > I think the pen needles are pretty interchangeable as I use the same needlea on the Novopens and the Humalog pens. Yes, most needles are interchangeable. I use BD 8 mm and Owen Mumford 12 mm needles on my pens. The exception is the NovoTwist needles, which only work on Novo pens. ---
