What is the 500 rule for insulin?

Use the 500 Rule to estimate insulin-to-carb ratio: 500/TDD = number of carb grams covered by a unit of insulin. Example: 500/50=10; 1unit of insulin will cover about 10 grams of carbohydrate.

How many units of insulin per day is normal?

For most people, this is about 24 units in 24 hours. The amount of background insulin does not depend on what you eat, and the dose should be low enough to allow you to miss meals without the risk of low glucose (a hypo), whilst still keeping the glucose levels within the target range.

How much does 1 unit of insulin bring down blood sugar?

One unit of insulin should cause your blood sugar level to drop 30 to 50 mg per dL, but you may need more insulin to get the same effect.

How many units is 10 mL of insulin?

Insulin vials have U-100 insulin. That means there are 100 units of insulin in each milliliter (mL) of insulin. Humalog® insulin comes in 3 mL (300 units) vials or 10 mL (1000 units) vials.

Is 2 units of insulin a lot?

One option is to choose a starting dose based on a person’s weight. Eventually, many people with Type 2 diabetes will require 1–2 units of insulin for every kilogram of body weight; that is, an 80-kilogram (175-pound) person will require at least 80 units of insulin each day.

What is the rule of 1500?

For regular insulin, use the “1500 rule.” This tells you how much your blood sugar will drop for each unit of regular insulin. For example, if you take 30 units of regular insulin daily, divide 1500 by 30. This equals 50.

What is the 450 rule for insulin?

Alternatively, the insulin-to-carbohydrate ratio (ICR) may be determined by the “450 rule.” To determine the ICR, divide 450 by the child’s total daily dose of insulin (TDD). For example, for a child with a TDD of 36 units, the ICR would be 450/36 = 12.5, or 1 unit per 12 g of carbohydrate.

How many units of insulin should I take if my blood sugar is 400?

70-139 mg/dL – 0 units 140-180 mg/dL – 3 units subcut 181-240 mg/dL – 4 units subcut 241-300 mg/dL – 6 units subcut 301-350 mg/dL – 8 units subcut 351-400 mg/dL – 10 units subcut If blood glucose is greater than 400 mg/dL, administer 12 units subcut, notify provider, and repeat POC blood sugar check in 1 hour.

When not to take insulin?

Never take insulin if it has not been prescribed to you by a doctor. Taking insulin when your body already has enough can be dangerous and possibly life-threatening. Insulin is a crucial hormone which, among other functions, helps the body control blood sugar levels.

How do you calculate insulin dosage?

Calculate Insulin Doses Using Your Insulin-to-Carb Ratio. The Academy of Nutrition and Dietetics clearly explains how to calculate an insulin dose for food: Add up the grams of carbohydrate in the foods you will eat. Divide the total grams of carb by your insulin-to-carb ratio.

How to calculate an insulin dose?

Log your insulin doses over the course of a week. Track every insulin dose, both fast-acting and long-acting. For example, if you take 20 units of long-acting insulin twice daily, and then an average of 4 units per meal, you take 52 units of insulin daily. Divide that total in half.

Can you take Humalog and Lantus together?

Yes you can take them at the same time, but not in the same syringe or the same exact injection site. You would usually take the Humalog a little before (or same time) as eating carbs/meals, and/or to correct a high bg. Lantus is usually taken either in the morning or at bedtime (and sometimes split into 2 doses per day).
