Which Plan Is Right for Me?
Over the last decade, several new insulin options have been introduced to the market. As a result, your healthcare team has more options than ever before when it comes to creating a treatment plan just for you.
Insulin therapy is not "one size fits all." Different people need different insulins. The insulin plan that's right for you will do two things:
- Fit your life — What do you do? When do you do it? Let your healthcare team know your usual routine. Or, tell them if you don't have one. The details of your life will make some insulins a better choice than others.
- Match your body's needs — You need some insulin all the time, more when you eat, and less when you exercise. If you have type 1 diabetes, all of those needs will be met by your injected insulin. If you have type 2, some of the needs may be met by your body's own insulin.
There are a lot of ways to combine insulins to meet those different needs. Your healthcare team will help you figure out which is right for you.
How much insulin do you need?
Here are some of the things that affect your need for insulin:
- how much you weigh
- how much you exercise
- how fit you are (how much fat and muscle you have)
- how sensitive your body cells are to insulin
- how much you eat and the foods you choose
- your emotions (such as your amount of stress)
- what other medicines you take

Getting the right insulin dose is a lot like tailoring a suit. You might start with a suit right off the rack. Then, the tailor nips and tucks until it's just right. It doesn't matter how large or small the suit is. What matters is that it fits you. Your blood sugars tell you when you've got the right fit.
How much insulin will I receive?
Just as height is measured in inches, insulin is measured in "units." A unit is a small amount of pure insulin.
- Vials of insulin sold in the United States have 100 units of insulin in each milliliter of fluid. Such vials say U-100 on the label. The amount of insulin in a milliliter (U-100) is called the insulin's concentration. Each vial contains 1000 units.
- A box of 5 Prefilled Pens contains the same amount of insulin as 1.5 vials.
