A doctor may recommend a more concentrated form of insulin to manage patients with diabetes who require higher insulin doses. There are now several different types of concentrated insulin available in the United States. Insulin is classically prescribed at a very specific concentration – called U-100. The U stands for units. The 100 stands for the number of units present in the liquid (1 milliliter). U-100 insulin has 100 units in 1 milliliter. U-100 is also referred to as “regular” insulin, but this is misleading since many different types of insulin come in this concentration.
Your doctor might recommend:
Changing all of your shots over to a concentrated insulin
Changing only the long acting insulin shot or the shot you take at meal time
These are the different types of concentrated insulin:
This U-100 abbreviation is similar to what beer companies use when they provide the percentage of alcohol (alcohol by volume) on the bottom of a beer bottle. Beer that contains 5% alcohol is not as strong as one that has 9% alcohol. The higher the concentration percentage, the more alcohol you are drinking in the same 12-ounce bottle. In a very similar way, U-200, U-300, and U-500 are more concentrated forms of insulin – meaning they have much more insulin in the same amount of liquid. If you took the same size injection of U-500 (as compared to U-100) you would get 5 times the insulin! This is like drinking a beer that has 25% alcohol. Be prepared to get drunk on much less!
