Insulin nomenclature is clearly confusing. Among other reasons:
The same product may have several different names; the names may be different in the U.S. compared to other countries; the same product may be made by several manufacturers and given differing names.
The product may be from different sources (previously all insulin came from animal pancreases: beef, pork, or mixed beef/pork; but now-a-days, insulins usually are semisynthetic human).
Insulins are classified by duration of action, as being rapid, intermediate, and prolonged.
Several manufacturers may also mix two insulin products into the same vial, producing mixtures of 70% one and 30% another, or 50/50. To make it worse, what the US calls 70/30 would be called 30/70 in Europe! And in the US, 70/30, 75/25, and 50/50 are the usual mixtures, but in Europe there will be others such as 80/20 (oops, 20/80).
Some of the "big players" in the insulin arena are described below. I give the U.S. brand name first, then common na...
Generic Name: INSULIN LISPRO - INJECTION Pronounced: (IN-sue-lin LISS-pro) Humalog SubQ Uses
Insulin lispro is a man-made product almost identical to
human insulin that is used to treat diabetes mellitus. Like other insulin
products, it works by helping sugar (glucose) get into cells. It starts working
faster and lasts for a shorter time than regular insulin.
Insulin lispro is usually used in combination with a
medium- or long-acting insulin product injected under the skin to control high
blood sugar. In some diabetics, insulin lispro may be used alone or with oral
diabetes drugs (e.g., sulfonylureas like glyburide or
Even with diabetes, you can lead an active and healthy
life if you eat a balanced diet, exercise regularly, and take your insulin as
directed. Controlling high blood sugar helps prevent kidney damage, blindness,
nerve problems, loss of limbs, and sexual function problems. Proper control of
diabetes may ...
For several years, I've been on Humalog (insulin lispro) with my insulin pump, after switching from Novolog (insulin aspart) because it was indeed having too long a "tail" for me to accurately calculate my doses. (The "tail" is an extremely long duration of action after the peak occurs.) I'm not the only one: Google "Novolog tail" and you'll find others with the exact same concern, especially with insulin pumps.
I've been with three different insurance plans since on the pump; the first two both covered Humalog without problem, so when my employer changed insurance plans on January first this year, I had no reason to anticipate any problem with getting my Humalog refilled by the third insurance plan.
So I imprudently let my supply of Humalog drift down to the final vial, and I've got about a week's supply left before it runs out. (Yeah, I know that's stupid - I could accidentally drop the vial and bust it, but I haven't done that yet in the four years I've been pumping. ...
