My boyfriend accidentally switched his Lantus and his Novolog. We spent the morning in the ER.

He took his morning insulin (he's on Dexcom/MDI, has an appointment to start Omnipod), left to run errands, and called me a few minutes later saying his sugar was crashing. Realized he'd accidentally taken 16 units of Novolog instead of Lantus, which is a MASSIVE dose for him. Went from 300 to 100 in 15 minutes and still going down. I went to get him. He pounded a couple of sodas and a handful of candy and it was still dropping. We went to the ER and it hit the 60s despite the belly full of sugar. Scared us. They had him drink 2 OJs and two packets of peanut butter and he still wasn't coming up. They finally got him stable on IV dextrose.

Love him to death. Shook me up. Scared him too. Double check your vials, friends.
