Proper and Correct way of Insulin unit calculations

The cost of one insulin vial varies depending on the type of insulin you use and how you are paying for it. But, no matter the cost, there are alternatives to paying cash price.

If you do not have insurance, the pharmaceutical companies that make insulin products offer patient assistance programs, explains Michael Carnathan MD, a board-certified family physician in Bethlehem, Pennsylvania. Most of the time, the patient can get the insulin for free or at a very reduced cost.

For those without health insurance, the older human insulins cost anywhere from $25 to $100 per vial for example, Walmart has human insulin available at $25 per vial. The newer human analog insulins cost between $174 to $300 per vial, according to a report published in 2018.

How Do Scientists Produce Insulin

Are you curious to know about the synthesis of insulin in industries? Yes! So let me explain the process in simple words.

  • First of all, scientists manufacture the gene of human insulin.
  • Then, scientists insert this gene in bacteria through plasmid. Now they are recombinant bacteria.
  • Then, these bacteria are put in large fermentation tanks.
  • Here, the bacteria will produce insulin using the gene.
  • Finally, scientists collect prepared insulin for human use.

Calculating Insulin To Carb Ratio

So how do you figure this all out?

Again, this is not something you ought to attempt to do alone, but always discuss with your physician and diabetes educator.

However, a general starting place is often 2.8x body weight divided by your current daily dose.

For example, if a 160 pound person were taking 50 units of insulin daily: 2.8 x 160 / 50 = 9.

In other words, its estimated that 1 unit of insulin would cover 9 grams of carbohydrates.

Now again, remember this is an estimated starting point, from here, youd tweak as needed based on your blood sugar log, which you are diligently keeping right???

Intensive Insulin Therapy Requires:

With MDI, insulin glargine or detemir is used to provide basal insulin and insulin aspart, glulisine or lispro provide bolus coverage.

With an insulin pump, insulin aspart, glulisine or lispro provide both basal and bolus insulin replacement.


The modules can be read in any order.

However, if you are newly diagnosed, it is best to start at the beginning in Understanding Diabetes, and work your way through the material.

Below you will find a guide to each module.

As you will see, depending upon your individual therapy, you can choose exercise guidelines and self-management sections that are specific for your diabetes treatment. Additionally, throughout the program, Self-assessment quizzes are available to help you monitor your progress, and how much you are learning.

The High Blood Sugar Correction Factor:

1 unit insulin lowers glucose by how much? Calculating ...

Correction Factor = 1800 ÷Total Daily Insulin Dose = 1 unit of insulin will reduce the blood sugar so many mg/dl

This can be calculated using the Rule of 1800.


= 1800 ÷ TDI = 1 unit insulin will drop reduce the blood sugar level by 45 mg/dl

While the calculation is 1 unit will drop the blood sugar 45 mg/dl, to make it easier most people will round up or round down the number so the suggested correction factor may be 1 unit of rapid acting insulin will drop the blood sugar 40-50 mg/dl.

Please keep in mind, the estimated insulin regimen is an initial best guess and the dose may need to be modified to keep your blood sugar on target.

Also, there are many variations of insulin therapy. You will need to work out your specific insulin requirements and dose regimen with your medical provider and diabetes team.

What Is An Insulin

Your insulin-to-carb ratio indicates how many grams of carbs one unit of rapid-acting insulin covers to ensure that your blood sugars stay in your desired range.

Your carb ratio is often initially set by your doctor when you are diagnosed but should be updated regularly . A carb ratio of 1:10 means that that 1 unit of rapid-acting insulin will cover 10 grams of carbs. A higher ratio indicates that you need less insulin to cover your carbs.

Let me give you an example:

If my carb ratio is 1:10 and Im eating 30 grams of carbs, Ill need 3 units of rapid-acting insulin to cover the meal , however, if my carb ratio is 1:15 Ill only need 2 units of rapid-acting insulin

That a higher carb ratio means less insulin can take a little time to wrap your head around but its an important fact when you start adjusting your carb ratio.

If you time the peak of your insulin with your meal, an accurate carb count combined with an accurate carb ratio will mean that your blood sugar should stay within your desired range and below 180 mg/dl .

If the timing of your insulin for the meal is off, but your carb count and carb ratio is right, you might see your blood sugar go slightly out of range but it should be back in range within 90 minutes

Side Effects Of Abnormal Insulin Levels

Since the insulin is so important to us, its vital to maintain normal insulin level. But what if you have abnormal insulin levels?

Side Effects of Low Insulin Levels

The blood sugar level can become elevated if there are reduced amounts of insulin secreted into the blood or the body cells become desensitized to insulin . If this is not carefully managed, patients may develop problems such as kidney disease, nerve damage or loss of vision.

Side Effects of Excessive Insulin

The side effects of excessive blood insulin include:

  • You may experience increased hunger, together with cravings for sugar and carb-rich food. In turn, you will gain weight.
  • Reduced levels of the mineral magnesium in your body cells. Magnesium is needed to relax your blood vessels and promote good blood circulation.
  • Increased retention of sodium, which in turn results in body water retention, leading to hypertension.
  • Lowered levels of beneficial high density lipoprotein , and increased levels of harmful low density lipoprotein and triglycerides. All these factors contribute to the development of heart disease.
  • Increased quantities of inflammatory compounds in the bloodstream. These can directly damage the walls of blood vessels and promote the formation of clots, which could result in respiratory failure or a heart attack.
  • A possible higher risk of cancer. This is because insulin promotes cell proliferation.
  • Fatty liver, polycystic ovary syndrome and increased blood pressure can also happen.

How Much Does 1 Unit Of Insulin Bring Your Sugar Down

Question Originally asked by Community Member karen How Much Does 1 Unit Of Insulin Bring Your Sugar Down Using a chart to give my mother her insulin, sometimes it just seams its not bringing her sugar down to a lower level. Answer The âcorrection factorâ is the term used for the amount of insulin a person needs in order to bring their blood sugar down to 120. It is different for everyone! Your motherâs endocrinologist should have a note of what this dose has been in the past, but you can also figure this out purely by conducting SAFE trial and error. If her blood sugar is at 200, try giving her one unit of insulin and test her blood sugar a half hour later, and then an hour later. If itâs still high, give another. For example, in MY body, if my blood sugar is at 200, I take two units of insulin to bring it down to 100 to 120. If I was going to be doing any exercise also at this time, i would only take one unit as my âcorrection factorâ because the exercise would help bring the blood sugar down, too.

What Is Insulin To Carb Ratio

U-100 Insulin Dosage Calculation (Two Examples)

So what is the solution?

Something called an Insulin to Carb Ratio: the number of grams of carbohydrates covered by 1 unit of rapid acting insulin.

This is different for different peoplethose who are more sensitive to insulin will have very high ratios a small amount of insulin will cover a lot of carbs. Whereas those who are more insulin resistant will have lower ratios the same amount of insulin will cover fewer carbs. So its important to know how many carbs a certain amount of insulin will cover for you.

In this example, we need to know how many carbs you ate Monday and establish a ratio based on that. So lets say you ate 30 grams of carbohydrates.

That would give us: 10 units for every 30 grams, therefore a 1:3 ratio. In other words, 1 unit of insulin for every 3 grams of carbs.

Now once you know this ratio, you can adapt/modify it for varying amounts of carbohydrates at meals. For example, if you ate 9 grams of carbohydrates, youd give yourself 3 units , if you ate 21 grams of carbs, 7 units and so on.

Now to complicate this even further, you may need to add a sliding scale to this.this accounts for an already elevated blood sugar that needs to be corrected.

For example, if your I:C ratio was as above, that would be the perfect amount of insulin to give if your blood sugar was already in range. However, if your blood sugar was high, say 325 , you need to do more to account for a high level.

Converting Insulin Milliliters To Units

While we are on the subject of converting units of insulin to milligrams, it is important to discuss a common source of confusion regarding insulin dosing, which is the relationship between milliliters and units.

Insulin products are listed in terms of a concentration, such as U100 or U500.

U40 stands for:

  • 40 Units of insulin per 1mL

U100 stands for:

  • 100 Units of insulin per 1mL

U500 stands for:

  • 500 Units of insulin per 1mL

So, if you have a U100 insulin product, and you need to inject 50 units, that would come out to 0.5 mL.

Similarly, if you have a U500 insulin product, and you need to inject 50 units, that would come out to 0.1 mL.

You can convert between units and mL for the most common type of insulin concentration, U100, below.

U100 Insulin to mL Converter

Type in units of U100 insulin to convert to mL:


Milliliters: 0

If you are using syringes to draw up and inject your insulin, it is vitally important to be sure you are using the correct ones to prevent dosing errors.

For example, you cannot use U100 syringes if you are utilizing a U500 insulin product.Drawing up half-way, to 0.5 mL, on a U100 syringe will equal a dose of 50 units of a U100 insulin. However, doing the same with a U500 product would yield 250 units!

History Or How This Came About

The history of the insulin Unit has been well reviewed elsewhere,, but it is, in short, a history of change. Originally defined as the amount of insulin required to cause convulsive hypoglycemia in a fasted 2kg rabbit, standards for potency have changed with improvements in the preparation and stabilization of insulin in solution. Where potency was defined in the 1920s as 8IU/mg of insulin, this definition was revised upward in 1959 by the World Health Organization Expert Committee on Biological Standardizations Fourth International Standard to 24IU/mg. It was revised upward again by the same committee in the 1986 to 26IU/mg., This value remains the standard to date, with the latest updates made in 2010.

However, as the 1986 standard contains some water and salts, amino acid analysis gives a corrected potency of 6 nmol per 1IU., If instead, anhydrous insulin is considered, the 6 nmol per 1IU potency is equivalent to 28.8IU/mg, or 0.0347mg/IU. This latter potency is more common and has been referred to as the established standard.

As a result, there is one standard, but two human insulin potencies due to improvements in the quality of insulin preparation. The conversion factors arising from these different potencies are given in . The conversion factor resulting from the Fourth International Standard was calculated as per, and can still be occasionally found .

Insulin Prices Are Dramatically Higher In The United States Than In Other Countries

For Release

TuesdayOctober 6, 2020

Insulin prices are more than eight times higher in the United States than in 32 high-income comparison nations combined, according to a new RAND Corporation study.

The study compared how much different types of insulin sold in the United States would cost if bought at prices in other countries. The average price per unit across all types of insulin in the United States was $98.70. Other countries would have paid a fraction as much for the same insulins.

U.S. prices were higher than each of the 32 comparison countries individually, ranging from 3.8 times higher than those in Chile to 27.7 times those in Turkey. U.S. prices were 6.3 times higher than those in Canada, 5.9 times higher than those in Japan and 8.9 times higher than those in the United Kingdom.

The study used manufacturer prices for the analysis. The final, net prices paid for insulins are likely to be significantly lower than manufacturer prices in the United States because rebates and other discounts often drive down the price paid by individuals in the United States.

But even if such rebates and discounts drive down prices by as much as 50%, the prices paid by U.S. consumer are likely to be four times the average paid in other high-income nations, according to the study.

The study was sponsored by the Office of the Assistant Secretary for Planning and Evaluation in the U.S. Department of Health and Human Services.

Without a doubt, insulin is lifesaving, and just a day or so without it will require hospitalization and could lead to death for those patients.

If someone has type 1 diabetes or if someone has had damage to their pancreas, these are instances where their body doesnt produce any insulin, Stephanie Redmond, PharmD, CDE, BC-ADM, founder of Diabetes Doctor, tells Verywell. Without a doubt, insulin is lifesaving, and just a day or so without it will require hospitalization and could lead to death for those patients.

How Can I Lower My Blood Sugar Overnight

Whether or not you have diabetes, follow these tips to avoid waking up with low blood sugar:

  • Eat balanced meals with healthy carbohydrates, proteins, and fats regularly throughout the day.
  • Have a bedtime snack.
  • If you drink alcohol, avoid excessive intake and have a snack with it.
  • Avoid exercising too much at night.
  • Are Insulin Vials Cheaper Than Pens

    There is a significant difference in insulin prices between insulin vials and insulin pens. Using vials is less expensive than pens. However, some people feel that using pens as a delivery system provides a higher quality of life. The pens come prefilled, and when using the analog medications, the number of doses could be lower. The pens make it easier to take insulin with you, providing more freedom.

    Using pens is safer, more convenient, and offers better glycemic control, according to a study published in 2018. However, this study also noted that people who use pens were spending significantly more each month for diabetes control. In some cases, it was three times more expensive to use pens.

    How Much Does A Month Of Insulin Cost

    Everyone has different insulin needs. There isnt a one size fits all approach to determining how much insulin you need. Those taking analog insulin take a background or basal dose once or twice a day. In contrast, those taking regular human insulin take it three to four times a day.

    This cadence is the only insulin some people with type 2 diabetes need. But for type 1 diabetes, and some with type 2, additional insulin is needed at mealtime. Depending on which insulin you are using, it should be taken 10 to 30 minutes before your meal. The amount of insulin depends on what you plan to eat. For example, you might need 1-3 units per carbohydrate portion .

    People with type 1 diabetes generally use two different types of insulin per day. They start with two injections per day and progress to three to four doses per day, according to the American Diabetes Association . People with type 2 diabetes might start with 0.5-0.8 units per kilogram of body weight per day and eventually take 1-2 units per kilogram of weight. For a person weighing 150 pounds, this would be 68 to 136 units per day. For a person weighing 175 pounds, this would be 80-160 units per day.

    One vial of insulin contains 1000 units, and pens contain 300 units.

    Things To Remember In Order To Change Insulin Doses:

    Calculating Premeal Insulin Dose
    • If the pattern happens at the blood sugar check before breakfast, change the long-acting insulin dose by 10 percent.
    • If the pattern happens at the blood sugar check before lunch, change the breakfast rapid-acting insulin dose by 10 percent.
    • If the pattern happens at the blood sugar check 2 to 3 hours after lunch, change the lunch rapid-acting insulin dose by 10 percent.
    • If the pattern happens at the blood sugar check 2 to 3 hours after supper , change the supper rapid-acting insulin dose by 10 percent.
    • If your blood sugar is above 180 two to three hours after a meal, ask yourself what caused this.
    • Common reasons for high blood sugar 2 to 3 hours after eating are:
    • Not taking insulin at least 15 minutes before eating
    • Eating too much carbohydrate or too much quick-acting carbohydrate
    • Not taking enough insulin to cover the carbohydrate
    • Not eating protein or fat in your meal
    • Eating a very high fat meal

    If you rule out numbers 1 and 2, you may need to take more insulin next time.

    • If the pattern is high blood sugar, you will increase the insulin dose that affects that column of blood sugars.
    • If the pattern is low blood sugar, you will decrease the insulin dose that affects that column of blood sugars.
