Customer Question

Good morning all. It is another beautiful day in Idaho. At my age every day is beautiful when I get up. My question is: Is there a medical reason why I must fill my insulin syringe
with NPH human novolin r (clear) before NPH human novolin N (cloudy).??. I take 50 units nph n plus 5 units nph r in the pm. Please explain it to me in non medical terms as best as possible.
Sincerely,
John Planinshek ***@******.***

Hi there,This is Dr Basu, experienced Internal Medicine Specialist.I am here to address your concerns and provide great service.Yes this is to make sure novolin N does not get mixed into the novolin R vial.That will change the action time of the R insulin.R insulin is supposed to act faster than N insulin.By takin R insulin first you avoid contaminating the vial with N insulin during drawing.Best wishes,It was my pleasure to help you today.If I have answered all your questions, Please rate my response Excellent (click on the 5th star).Please bookmark my profile for fast, reliable and authentic answers!This is the link to my profile:http://www.justanswer.com/medical/expert-mysticdoc/
