Fiasp Woes

Now that I’ve had a month or so of experiences with Fiasp, I wanted to share something that can be frustrating with a faster acting insulin.

It works quickly.

Honestly, sometimes too quickly. But this is a user error. I need to learn how to adjust and time my injections better. I am far too used to pre-bolusing with Novolog (Novorapid).

Case in point today: I took enough Fiasp to cover 100g of a Chocolate Croissant, yeah you should be jealous! The issue today is that I didn’t start eating fast enough. I took insulin and waited about 15 minutes before eating. (Please note: Fiasp package instructions say 2 minutes before a meal or 20 minutes after, don’t follow my ignorance.)

Hindsight is 20/20.

I hovered around the 60-70 mg/dl mark for about two hours after eating. However, the chocolate croissant could not catch up to my Fiasp injection. I ended up over-treating with a piece of bread, ok, two. It was the worst two and a half hours I’ve had in ages. Had I just eaten the croissant when I took my bolus, I could have avoided this issue.

In reality, I couldn’t even enjoy my lovely chocolate croissant because all I could focus on was low trending BGs and the annoying instinct to scarf food.

What are your experiences with Fiasp?

    1. Hi Hazel. I’m glad you found my information helpful. Have you started using Fiasp? Can you explain what bottom source you are referring to? The last link about human instincts is an opinion piece written by me.
