Do I need to worry about insulin strength?

Today, if you buy insulin in the United States, you don’t have to worry about the strength. Nearly all insulin preparations sold in the United States and Canada today are of the same strength: U-100. This means that they have 100 units of insulin in every cubic centimeter (cc) of fluid. U-500, a highly concentrated preparation, is available only by special order for people who have developed insulin resistance and need to take extremely high doses of insulin. Hospitals sometimes use U-500 insulin for emergencies.
