The cloudy/clear mixed injection conundrum

Recommended Posts

I've been using NPH and R. Am curious about the mixing. How is it that cloudy contaminates clear but not vice-versa? They sell mixed, right? Do they suggest doing it that way to keep the clear fluid clear?

Turns out that NPH = R + Protomine. If you get protomine in the R because you first dipped in the NPH, it can change the characteristics of the R such that it acts more like NPH. (In other words, take longer to kick in.) When you go clear ® to cloudy (NPH), no worries regarding contamination.

Learn something new every day. While I haven't used NPH and Regular in the past 25 years, I know a lot of people do. Good info.

I thought I'd give the N/R routine a shot since because of the cost savings. So far so good. I've been doing a good job of timing the N such that it spikes in the morning, and my fasting bg is actually on the mend. Two issues: R takes a long time to kick in and is a little more difficult to schedule. Has to stay refrigerated.
