Humalog is the safest, onset is about 2 minutes, peak around 25 and is out within hour and a half...
Thats not true for Humalog.
http://www.aafp.org/afp/980115ap/noble.htmlFrom the paper in the American Family Physician:
Insulin lispro begins to exert its effects within 15 minutes of subcutaneous administration, and peak levels occur 30 to 90 minutes after administration. Duration of activity is less than five hours
Humalog has a very fast onset of action, but no insulin will begin to have an effect within two minutes of administration if its administered appropriately subcutaneously. There has to be time for it to enter the blood stream.
Also, my understanding is that NYC is in the process of mandating that the medical information of all diabetics in the metropolitan area is stored in a centralized data bank that all pharmacies and physicians will have access too. This translates into the end of OTC sales of ALL diabetic supplies without being registered or a valid prescription from a doctor licensed in New York.
My understanding is this system---if it overcomes the challenges to it as a violation of patient confidentiality rights and civil liberties is also being considered in other major metropolitan areas (Chicago, LA, Washington DC, Philadelphia). Its similar to the states (like alabama) that are now requiring all diabetics to present a signed physician statement prior to being issued a drivers license. The differences is that not everyone has access to the DMV's database.
I fully expect Regular and NPH insulin to be prescription only within the next 3 years, faster if the next president does something in terms of national health care. Its just a matter of time.
