Hi,
Foy my dd, HumulinR is about 2 times less potent. We followed Dr. B's instructions and injected, then tested every 10 minutes. It does take 45-50 minutes to start working for her. I thought this would stress me out, but it actually turned into a blessing for us....since we do the shot well in advance of a meal, it takes the "shot stress" away from getting the meal on the table. And for me with four kids including a toddler....wow...sooooo much better! We do always have the Humulog on hand for corrections and or road trips where we can't plan meals, etc.
