What brand is it?

I've taken Humalog before and thankfully I didn't have really any side effects I take novolog currently and have for a while without any side effects. I know that as soon as I take it within 5 minutes I have to eat something. It's not near as fast acting as f i a s p. Dang talk to text I have to literally spell out the word

I've switched between novolog and Humalog and novolog and generic insulin aspart before without any issues. Best of luck!

I had to switch as well a few years ago for to insurance I was nervous as well go but my doctor back then was great about it. Made sure I was on the correct amount every 3 days I had to call it was like the first month
