Limitations And Additional Considerations

Diabetes Bootcamp: How fast acting insulin works (Part 1 of 3)

Additional considerations when evaluating the option of using a faster-acting insulin include the patients age and pregnancy status, the ease of acquisition and cost of the medication, and the medications long-term clinical and safety outcomes. Although faster aspart is approved for use in both children and adult patients , URLi is only approved for use in adult patients at this time it has not yet been studied in children, and therefore its safety and efficacy in children with type 1 or type 2 diabetes are unknown .

Medication acquisition and costs should be considered when initiating or adjusting therapy. The costs of the ultra-rapid-acting insulin analogs are similar to those of rapid-acting insulin analogs . For patients who have medication acquisition issues or for whom cost is a primary concern , clinicians may consider prescribing more affordable bolus insulins such as regular human insulin, including the Walmart-branded ReliOn Novolin regular insulin or the biosimilar insulin lispro analog Admelog . For patients with commercial or government insurance, the drug formulary should be reviewed first to select the plans preferred bolus insulin agent.

In collaboration with patients and caregivers, other important factors should also be taken into consideration when starting or switching to a particular bolus insulin and delivery device.

How To Take Long

Usually, you inject long-acting insulin once a day to keep your blood sugar levels steady. You use a needle or pen device to give yourself the injection. Be sure to inject your long-acting insulin at the same time every day to avoid lags in insulin coverage or stacking your insulin doses. Stacking means taking your doses too close together, causing their activity to overlap.

Your doctor might recommend adding short-acting insulin before a meal to prevent a blood sugar spike after you eat.

If you change brands of long-acting insulin, you may need a different dose. Talk to your doctor for advice if you change brands of any insulin.

As with any medicine you take, insulin injections can cause side effects.

One possible side effect is low blood sugar . Symptoms of low blood sugar include:

  • dizziness
  • headache
  • fainting

Other possible side effects of insulin injections include pain, redness, or swelling of the skin at the injection site.

Sometimes insulin is given in combination with thiazolidinediones. This drug group includes oral diabetic drugs like Actos and Avandia. Taking insulin with thiazolidinediones increases the risk of fluid retention and heart failure.

For those taking degludec, precautions may be necessary because of its long effect in the body. You doctor may need to increase your dose at a very gradual rate, at least three to four days apart. It will also take longer to clear the drug from your body.

How To Know If Mealtime Insulin Is Right For You

Most doctors will start you on a long-acting insulin at first. But sometimes long-acting insulin isnt enough to keep your blood sugar at your target level throughout the day.

When you eat a meal, sugar levels in the blood can rise rapidly. This spike in blood sugar may be too high for long-acting insulin to control. This is when your doctor may want to add a mealtime insulin to your long-acting therapy or prescribe a combination insulin.

Your doctor will work with you to figure out if you need a mealtime insulin. They will have you take note of how much your blood sugar fluctuates throughout the day. Theyll also ask about your lifestyle and eating habits.

Your doctor will likely recommend that you add a mealtime insulin to your long-acting insulin if your glucose levels are still too high after eating a meal.

Youll continue to take your long-acting insulin as prescribed by your doctor. But youll also take the mealtime insulin right before you eat your meals .

Indications Dosing And Administration

Insulin lispro is available only by prescription and is indicated for the management of hyperglycemia in patients with diabetes mellitus. Guidelines for glycemic control are listed in Table 4.20,21 Because of its more rapid onset and shorter duration of action, insulin lispro should always be part of a regimen that includes a longer-acting human insulin,5 except when continuous subcutaneous insulin infusion therapy is used.22

Based on product information from Eli Lilly and Company, the dosage of insulin lispro should be individualized, with therapy initiated as outlined in Table 5. Patients who use insulin lispro should monitor their blood glucose levels frequently, especially their postprandial levels. The U.S. Food and Drug Administration has not approved insulin lispro for continuous subcutaneous infusion therapy, although this method has been used in clinical studies. Insulin lispro also is not approved for intravenous or intramuscular administration.

What Are The Different Options For Taking Insulin

Fiasp insulin

There are three main ways of taking insulin:

  • Traditional vial and syringe

  • Insulin pen and pen needle. The pen is pre-filled with the medication, and a pen needle screws on to the top to give the shot.

  • Insulin pump, which delivers rapid-acting insulin continuously through an infusion set attached to the body.

In addition to different , there are different types of insulin, including:

  • Long-acting insulin, also called basal insulin.

  • Rapid-acting insulin for mealtimes, also called bolus insulin.

The traditional way to take insulin is by through multiple daily injections , with one injection of basal insulin daily and then rapid-acting insulin for mealtimes. This can require a person to take subcutaneous injections at least four times daily in order to keep their blood sugar managed.

This graphic shows the level of insulin over the course of a day in a person with type 1 diabetes who takes four daily injections of insulin, as compared with insulin in a person without diabetes, represented by the dotted red line. The gray line represents basal insulin, or glargine, which is injected once a day. The blue-shaded humps around mealtimes represent a shot of rapid-acting insulin for each meal.Insulin vial and syringe.Insulin pump.

Faster Aspart In Insulin Pumps

FAsp has been studied in the setting of insulin pump therapy , with an approximately threefold greater insulin exposure and an approximately 100% greater glucose-lowering effect in the first 30 min with FAsp compared to IAsp. In a crossover trial in adults with type 1 diabetes, FAsp delivered via an insulin pump produced a greater glucose-lowering effect than IAsp in the 2 h following a liquid meal .

In a 16-week trial, insulin pump therapy with FAsp resulted in similar changes in HbA1c to those achieved with IAsp . FAsp was, however, superior to IAsp in change from baseline in 1-h postprandial glucose increment after a meal test, with statistically significant reductions also observed at 30 min and 2 h. Furthermore, 1-h postprandial increments were lower with FAsp across all meals, as reflected by an interstitial glucose difference of 0.21 mmol/l.

Common Injection Sites For Insulin

There are various sites on the body that can be used for insulin injection, and the rate of absorption depends on the insulin injection site. In order of fastest to slowest absorption, the options are:

  • Abdomen

Rotating injection sites is key to avoid getting knots underneath the skin, which are called areas of lipohypertrophy. It is also very important to rotate sites with each injection and avoid injecting into areas of scar tissue.

For example, if you are injecting insulin into the abdomen , it helps to rotate injection sites around your belly button like a clock, making sure to be at least 2 inches from the belly button itself.

How Are You Doing

Measuring and observing your postmeal blood glucose values will help you to determine how well you are timing your rapid-acting insulin and figuring your doses. Walsh suggests that much of the postprandial high blood glucose values observed are because people arent giving rapid-acting insulin long enough before a meal to act in tandem with their food. Most foods affect the blood glucose within two hours, while most of the effect of rapid-acting insulin is seen over five hours.

The American Diabetes Association advises that postprandial blood glucose shouldnt exceed 180 mg/dl at two hours after the start of a meal. Other associations and experts believe the two-hour postmeal goal should be less than 140 mg/dl. Occasionally checking your blood glucose after a meal at hours one, two, and three can help you determine when your blood glucose level peaks and starts to come down again. According to Scheiner, Research shows that it is common for people to have elevated blood glucose levels after meals. One key to controlling these highs is better timing of rapid-acting insulin.

Is Short Acting And Rapid Acting Insulin The Same

Rapid-acting insulin: What you need to know

3.9/5Rapidacting

Herein, what is the difference between short acting and rapid acting insulin?

Shortacting insulins are used like rapidacting insulin to cover blood sugar elevation from eating. Intermediate-acting insulins are similar to long-acting insulins as they are used to cover blood sugar elevations when the rapidacting or shortacting insulins finish working.

Also Know, can you take long acting and short acting insulin at the same time? It starts to work within 1 to 3 hours, peaks between 4 to 9 hours and lasts for as long as 12 hours. Intermediate-acting insulin offers baseline insulin coverage, and it can be used together with rapidacting insulin and shortacting insulin.

Besides, which insulin is short acting?

Regular insulin is also known as shortacting insulin. It is also used to cover your insulin needs at mealtime, but it can be injected a little bit longer before the meal than rapidacting insulin. It also works in the body slightly longer than rapidacting insulin.

What is the onset of rapid acting insulin?

Rapid Acting Insulin Analogs which have an onset of action of 5 to 15 minutes, peak effect in 1 to 2 hours and duration of action that lasts 4-6 hours.

What Is Rapid Or Fast

By Elisabeth Almekinder RN, BA, CDE

You may take rapid acting or fast acting insulin for your diabetes, either through injections prior to your meals, or in your insulin pump. You may use it alone, or in combination with other insulins and diabetes medications, including injections and pills.

In a person without diabetes, the pancreas puts out small amounts of insulin, continuously bringing down blood sugars to a normal level with no difficulty. When a person has diabetes, they may not make any insulin, as occurs in Type 1 Diabetes. They may make some insulin, but its not working well, and its just not enough to bring blood sugars into a normal range, as occurs in Type 2 Diabetes.

When there is no insulin, or not enough insulin, the goal is to try to simulate what the body normally does to bring down blood sugars through injections of insulin, inhaled insulin, or via an insulin pump. To do this, rapid or fast acting insulin must be taken in relation to food that is eaten in many cases. Not everyone with diabetes must take insulin to control their blood sugars, though.

Lets learn how Christie uses rapid acting insulin

Things To Consider When Taking Rapid Insulin

The timing of your dose is important with relation to meals. You may not always be able to count carbohydrates, so there will be times when you really dont know how much you are consuming. This could happen over the holidays, at a friends house for dinner, or when you are out to eat when no nutritional information is available.

In some cases, the food may dictate the insulin, and not the other way around. For example, if your blood sugar is high right before your meal, you can use your insulin sensitivity factor. This is the amount that your blood sugar will go down with one unit of insulin.

Calculate what your dose is for coverage of the high blood sugar. Wait until you start trending down, then eat your meal. This works well for most insulin pumpers.

For those folks with diabetes who inject insulin, even if you use vials, it could be helpful to have an insulin pen around, which is more portable than vials of insulin. If your blood sugar is between 140 mg/dL and 180 mg/dL pre-meal, then take rapid insulin, and wait 30 minutes before you eat. If its higher, say between 180 mg/dL to 200 mg/dL, then waiting 45 minutes before eating may be warranted. If greater than 200 mg/dL, waiting an entire hour before eating may be warranted.

If you can check your blood sugar about an hour before your meal, you can do a correction dose of insulin an hour before your meal if your blood sugar is too high. That was, you will be trending a lower blood sugar when its time to eat your meal.

Which Insulin Products Last Longer Than Slow

The Newest Fast

Toujeo and Tresiba are referred to as ultra-slow-acting insulin products because they last longer than slow-acting insulin. Toujeo was approved in February 2015 by the FDA. It starts working within 6 hours and lasts for 36 hours without any peak.

Tresiba was approved in September 2015 by the FDA. It starts working within 1 hour and lasts for at least 42 hours. Just like Toujeo, it also has no peak.

What Drugs Interact With Humulin

Humulin N and Humulin R have the same interactions because they are both insulins. Interacting medicines include:

  • antidepressants, such as fluoxetine or escitalopram or monoamine oxidase inhibitors such as isocarboxazid
  • antipsychotics, such as aripiprazole or clozapine
  • clonidine
  • fluoroquinolones such as ciprofloxacin or levofloxacin
  • HIV medicines, such as atazanavir or ritonavir
  • hormones, such as estrogen, progesterone or testosterone
  • lithium
  • other antidiabetic agents, such as glyburide, or glipizide
  • pentamidine
  • salicylates, such as aspirin
  • salmeterol
  • some heart medications, such as beta-blockers ACE inhibitors , ARBs
  • sulfonamide antibiotics
  • turmeric.

What Are The 6 Different Types Of Insulin

If you need insulin, your doctor will recommend a specific type depending on your lifestyle, the type of diabetes you have, and your blood sugar levels at different times of the day. You may need more insulin coverage at mealtimes, overnight, or throughout the entire day. Currently, there are 5 types of injectable insulins and 1 inhaled insulin.

Lyumjev: The Newest Ultra

In June 2020, the FDA has approved a new ultra-rapid-acting insulin: Lyumjev by Eli Lilly. This insulin can be used for adults that have type 1 or type 2 diabetes. Ultra-rapid-acting insulin is designed to reduce blood sugar spikes that generally happen after a meal. It will initiate competition with Novo Nordisks ultra-fast-acting insulin, Fiasp which has been on the market since September 2017.

Research presented at the American Diabetes Association 79th Scientific Sessions in 2019 demonstrated that Lyumjev reached 50% of peak level at 13 minutes , with its first effect on blood sugar lowering 15 minutes after injection. Its full effect is seen over the first 2 to 3 hours, as one needs for covering the effect of meals. This may be a great option for people who are taking multiple daily injections of insulin, around mealtimes, and dont have the time or courage to inject 15 minutes before meals. Earlier studies compared A1c and post-meal blood glucose reduction using Lyumjev with Lillys existing rapid-acting insulin, Humalog. Both products showed a reduction in A1c, but Lyumjev showed a greater decrease in 1-hour and 2-hour post-meal blood glucose. Its important to emphasize that both Humalog and Lyumjev contain the same insulin, lispro, but 2 additives in Lyumjev enhance and speed up insulin absorption, leading to faster onset of its action. The current drawback of Lyumjev includes minimal research on how it affects diabetes control in children with diabetes.

What Type Of Insulin Is Best For My Diabetes

Long-acting insulin: What you need to know

Your doctor will work with you to prescribe the type of insulin that’s best for you and your diabetes. Making that choice will depend on many things, including:

  • How you respond to insulin.
  • Lifestyle choices. The type of food you eat, how much alcohol you drink, or how much exercise you get will all affect how your body uses insulin.
  • Your willingness to give yourself multiple injections per day
  • Your age
  • Your goals for managing your blood sugar

Your doctor may prescribe more than one type. You might need to take insulin more than once daily, to space your doses throughout the day, or to add other medicines.

Afrezza, a rapid-acting inhaled insulin, is FDA-approved for use before meals for both type 1 and type 2 diabetes. The drug peaks in your blood in about 15-20 minutes and it clears your body in 2-3 hours. It must be used along with long-acting insulin in people with type 1 diabetes.

The chart below lists the types of injectable insulin with details about onset , peak and duration . These three things may vary. The final column offers some insight into the “coverage” provided by the different insulin types in relation to mealtime.
