How to Mix Insulin NPH and Regular Insulin Nursing | Mixing Insulin Clear to Cloudy

Purpose of mixing insulin: To prevent having to give the patient two separate injections .

Most commonly ordered insulin that are mixed: NPH and Regular insulin .

Important Points to Keep in Mind:

  • Never mix Insulin Glargine Lantus with any other type of insulin.
  • Administer the dose within 5 to 10 minutes after drawing up because the regular insulin binds to the NPH and this decreases its action.
  • Check the patients blood sugar and for signs and symptoms of hypoglycemia to ensure they arent hypoglycemic if patient is hypoglycemic hold the dose and notify md for further orders.

Insulin Analogs Are Now Replacing Human Insulin In The Us

Insulins are categorized by differences in onset, peak, duration, concentration, and route of delivery.

Human Insulin and Insulin Analogs are available for insulin replacement therapy. Insulins also are classified by the timing of their action in your body specifically, how quickly they start to act, when they have a maximal effect and how long they act.Insulin analogs have been developed because human insulins have limitations when injected under the skin. In high concentrations, such as in a vial or cartridge, human clumps together. This clumping causes slow and unpredictable absorption from the subcutaneous tissue and a dose-dependent duration of action . In contrast, insulin analogs have a more predictable duration of action. The rapid acting insulin analogs work more quickly, and the long acting insulin analogs last longer and have a more even, peakless effect.

What Is Basal Insulin And What Is Bolus Insulin

Basal insulin is background insulin that covers your normal metabolism and insulin needs. Your pancreas normally makes set amounts of insulin around the clock, and basal insulin mimics this process, providing a background low level of insulin. Basal insulin is a slow and steady dose of insulin and can be given as an injection or through an insulin pump.

Bolus insulin is when insulin is given as a single, large dose to handle a rise in blood glucose, like the one that happens during eating. A bolus dose of insulin can be given as an injection or through an insulin pump. Bolus doses of insulin have a big effect in a short time.

S On How To Mix Insulin

1. Check the doctors order and that you have the correct medication:

Doctors order says: 10 units of Humulin R and 12 units of Humulin N subcutaneous before breakfast daily

Youre giving a total of 22 units

As the nurse, it is important to know the peak times of the insulin you are giving because this is the most likely time the patient could experience HYPOGLYCEMIA.

  • Regular insulin has an onset of 30 minutes, peak 2 hours, and duration of 8 hours
  • NPH insulin has an onset of 2 hours, peak 8 hours, and duration of 16 hours

Learn these insulin mnemonics to remember the onset, peak, and duration times.

2. Wash your hands and don gloves!

3.Roll the cloudy insulin vial in between the palms of the hands to mix the ingredients because if you dont mix the contents it can alter how much cloudy insulin you are actually drawing up. DONT SHAKE the vial because this will cause air bubbles!

4. Clean off tops of vials with alcohol prep for 5 to 10 seconds.

5. Remove cap from syringe.

6. Inject 12 units of air into the Humulin-N vial & then remove syringe from vial.

7. Inject 10 units of air into the Humulin-R vial & turn bottle upside down and then withdraw 10 units of clear insulinREMOVE SYRINGE.

8. Insert syringe into Humulin-N and turn bottle upside down and remove TOTAL UNITS NEEDED by pulling the plunger to 22 units

9. Recap the needle using the one-hand scoop techniqueif not using immediately.

Can Humulin R Be Taken With Levemir Not At The Same Time But Can Humulin R Be Taken At Meal Time And Levemir For Basal


Question Originally asked by Community Member fl98girl Can Humulin R Be Taken With Levemir. Not At The Same Time But Can Humulin R Be Taken At Meal Time And Levemir For Basal??? Answer Humulin regular can be used as a bolus insulin at meal time with Levemir as a basal. However, it is not recommended to be mixed together. Some health care providers use NPH/Regular at breakfast, regular at dinner and Levemir at bedtime to avoid the potential for lows overnight. Some also my use Levemir at Breakfast, regular at breakfast , regular at dinner and Levemir at bedtime. Hope this helps.

Nursing Care For Patients Having Insulin Injections

Administering insulin injections requires the nurse to be more careful, especially since apart from the need to calibrate doses, monitoring patient response to medication should be made. The following are nursing considerations for patients who are receiving insulin injections as part of their therapies for diabetes mellitus:

  • Perform a thorough assessment on the potential for contraindications or any complications arising from insulin therapy such as pregnancy, history of allergies, and other premorbid conditions.
  • Ensure that proper blood sugar monitoring is performed to help determine the need to adjust doses as needed.
  • Determine the level of physical activity and independence that the patient exerts so that the plan of care and other treatment regimes may be modified or changed according to his needs.
  • Monitor other laboratory values of the patient and involve him in planning for its monitoring, especially when the insulin therapy plans a long-term care management plan.
  • Work with the patient to ensure that his diet and activity plans help enhance the increased effectiveness of insulin therapy.
  • Provide teaching to the patient and his significant others the importance of following the recommended treatment regimen for the patient to prevent complications such as:
  • Proper diet
  • Adherence to medication regimen
  • Activity and other lifestyle factors
  • Ensure that the proper steps for preparing insulin injections are observed and taught to patients and their significant others:

    NPH +Regular insulin: Always draw the Regularinsulin into the syringe first. Phosphate-buffered insulinsshould NOT be mixed with lente insulins. Zinc phosphate may precipitate, and the longer-acting insulin will convert to a short-acting insulin to an unpredictable extent.

    One may also ask, how do you mix and administer insulin? Prepare the Insulin and Syringe

  • Remove the plastic cap from the insulin bottle.
  • Roll the bottle of insulin between your hands two to three times to mix the insulin.
  • Wipe off the rubber part on the top of the insulin bottle with an alcohol pad or cotton ball dampened with alcohol.
  • Correspondingly, when mixing insulin which is drawn up first?

    When you mix regular insulin with another type of insulin, always draw the regular insulin into the syringe first. When you mix two types of insulins other than regular insulin, it does not matter in what order you draw them into the syringe.

    What insulin Cannot mix?

    Some insulins, like glargine and detemer , cannot be mixed. Other insulins are already a combination of two types of insulin and should not be mixed.

    How Does A Person Mix Insulin

    Self-mixing insulin requires a person to inject themselves with two types of insulin in one injection.

    The types of insulin people can use are intermediate-acting insulin and short- or rapid-acting insulin. These insulins take different lengths of time to work, helping a persons blood sugar levels to remain steady throughout the day.

    A person can mix the two insulins in the following way:

  • Draw the short- or rapid-acting insulin into the syringe first. This insulin is clear.
  • Before drawing the cloudy intermediate insulin into the syringe, roll it gently between the palms 1020 times. This helps to mix the insulin suspension gently.
  • Once the cloudy insulin is mixed, draw it into the syringe with the clear insulin.
  • Inject the insulin mixture immediately.
  • Premixed insulin is a pre-prepared mixture of different insulins. Premixed insulin generally contains 7075% intermediate-acting insulin and 2530% short- or rapid-acting insulin.

    A person may prefer to use premixed insulin if they:

    • find it difficult to measure and draw up the insulin themselves
    • prefer the convenience of a premade solution
    • have variable eating and exercise patterns

    However, a person is unable to adjust premixed insulin. This means that if a person increases their pre-dinner dose of premixed insulin to offset high blood sugar levels before going to bed, they are at risk of overnight hypoglycemia. Hypoglycemia is when a persons blood sugar levels drop too low.

    How Do You Store Insulin

    Insulin Mixing- NPH with Regular- Nursing Skills

    Insulin is easily broken down by extreme temperatures, which means you need to be careful if you live in a part of the U.S. that gets very hot in summer, or very cold in winter.

    All unopened vials and cartridges should be kept in the fridge, between 36-46 degrees Fahrenheit . Discard any insulin that you think may have inadvertently got too hot or too cold. The expiry date on insulin applies to unopened, refrigerated insulin.

    How Is Insulin Administered

    Insulin is most commonly administered subcutaneously and there are three main delivery methods:

    • Insulin Pens: these hold a replaceable cartridge of insulin and use a replaceable needle to puncture the skin and deliver the insulin subcutaneously
    • Insulin pumps: these are small computerized devices that deliver a continuous supply of insulin under the skin. They are also known as continuous subcutaneous insulin infusion devices
    • Via a syringe and needle using a vial of insulin.

    An inhaled insulin is available for adults with type 1 diabetes that can be administered at the start of each meal. It is used in combination with a long-acting insulin and is not recommended in people who smoke or who have recently quit smoking.

    So far, nobody has successfully made an oral insulin tablet that delivers an effective dose of insulin. The problem is that insulin degrades in the stomach and intestine before it even has a chance to get absorbed into the bloodstream. In the hospital, insulin may be administered directly into a vein or into a muscle under certain circumstances.

    Mixing Nph And Regular Insulin For Injection

    Mixing Neil-Patrick-Harris-vial and Regular-vial with Insect-syringe9 KEY FACTSChecking Order

    The order and the number of units of NPH insulin and regular insulin should be verified in the medication administration record . Note that the shorter acting insulin is drawn up first. The proper supplies should also be selected including the vials of the insulin, syringe, alcohol pads, and proper PPE.

    Rolling Neil-Patrick-Harris-vial with Insect-syringe

    Roll the NPH insulin between your hands to evenly distrubute the medication throughout the vial. Upon completion of rolling the NPH insulin, it should appear uniformly cloudy.

    Alcohol-swab Wiping Multiuse Vials

    Multiuse vials require the use of an alcohol preparation prior to use of the vial for medication administration.

    Injecting Air into Neil-Patrick-Harris-vial with Insect-syringe

    An injection of air equal to the number of units of insulin allows for the medication to be easily withdrawn from the multiuse vial. Vials of medication are vacuum-sealed and failure to inject air into the vial first could create difficulty in attempting to withdraw the medication.

    Injecting Air into Regular-vial with Insect-syringe Withdrawing from Regular-vial with Insect-syringe

    Withdraw the number of units of regular insulin ordered into the syringe. Vials should be inverted to withdraw medications.

    What Else Should I Know About Insulin

    Our insulin requirements vary depending on the food we eat, how much activity we do, our general and mental health, how much we currently weigh, and our age.

    Talk to your doctor about how you should adjust your insulin dose when you:

    • Are prescribed other medications that may affect your body’s sensitivity to insulin
    • Are unwell or have an infection
    • Feel stressed or exceptionally tired
    • Gain or lose weight
    • Reduce or increase your activity levels
    • Are trying for a baby or find out you are pregnant.

    You should also regularly monitor your blood glucose levels and be able to count your calories and know how to calculate how much insulin to take and when to adjust it. If you don’t know how to do this, ask your doctor or talk to a diabetes nurse.

    You should know what to do if your blood sugar level goes too high or too low and have an action plan in place so that your family and friends also know what to do.

    Getting Ready To Inject Insulin From A Bottle

    Mixing NPH and Rapid/Short
    • Wash your hands. Use soap and clean, running water.
    • Check the expiration date on the insulin. Don’t use expired insulin.
    • Look at the insulin. Clear insulin should not be discolored or have crystals. Cloudy insulin should not have clumps or crystals stuck to the side of the vial or pen.
    • Wipe the top of the insulin bottle with alcohol.

    How Long Does Insulin Last Out Of The Refrigerator

    Opened and in-use cartridges and vials are fine to keep at room temperature for up to 28 days.

    The exception is Tresiba which, once in use, is stable for up to 8 weeks at room temperature.

    If you are going out in the sun, always use an insulated bag protected by a cool pack to ensure your insulin doesn’t heat up but avoid freezing it. During cold weather, keep your insulin supplies close to your skin so your body heat keeps them at a more even temperature.

    How Would You Prepare To Administer This Injection


  • Gather all of the equipment you will need
  • Wash your hands
  • Check the expiration date on the vials of insulin. If they are not expired, pick up the cloudy bottle of insulin and roll it between your hands until it is mixed, until there is no powder on the bottom of the bottle. Do not shake the insulin bottle because this can cause air bubbles.
  • Take the bottle of cotton ball dipped in alcohol and wipe the top of both insulin vials
  • Pick the Humulin N first and inject 30 units of air into the vial Mixing two types of insulin in one syringe
  • After putting air in the Humulin N do not draw up the insulin yet, just pull the needle out and insert 10 units of air into the Humulin R vial.
  • Then, after you inject the air into Humulin R turn the vial upside down to draw 10 units of Humulin R into the syringe.
  • Once you have drawn up yours 10 units, Insert the needle into the vial of Humulin N and draw the slower-acting insulin into the syringe

    Nph Insulin: Mixing Is Critical For Best Results

    With commentary by study author Geremia Brunetto Bolli, MD, professor of endocrinology, Perugia University School of Medicine, Perugia, Italy

    Patients on insulin known as NPH are often reminded that they need to re-suspend it before use by shaking it or rolling it in the palm of their hand.

    However, doctors know that patients often hurry and don’t take the time to mix up this kind of insulin before using it. Now, a new study suggests how crucial that step is. Italian researchers compared the effects of mixing or not mixing NPH insulin on the insulin concentrations in the blood.

    “It is well known that NPH insulin needs resuspension prior to its use,” says Geremia Brunetto Bolli, MD, professor of endocrinology at the Perugia University School of Medicine in Perugia, Italy, who led the study. “However, the different glucose lowering effect of re-suspended versus non-resuspended NPH was not known,” he says.

    In his study, he found that non resuspended NPH insulin ”may result in an approximately twofold difference” in the effect on insulin levels in the blood. His study was published online Sept. 10 in Diabetes Care. So it is important that NPH is properly resuspended prior to its use, says Dr. Bolli.

    NPH insulin use is probably more common overseas, he says, but is still in use in the U.S. “If you don’t turn it upside down, the insulin doesn’t disperse equally,” Dr. Mezitis says. And it doesn’t work as well. “The blood sugar is not going to be controlled as well.”

    Getting Rid Of The Syringe

    Mixing NPH and Regular Insulin
    • Put the needle and syringe in a sharps container. Dont recap the needle.
    • You can buy a sharps container at a drugstore or medical supply store. Or you can also use an empty laundry detergent bottle or any other puncture-proof container and lid.
    • When the sharps container is full, put it into a garbage bag and secure the top. Label the bag needles or sharps.

    How To Mix Insulin Clear To Cloudy

    Learn how to mix insulin clear to cloudy. Drawing up and mixing insulin is a skill that nurses will utilize on the job. Insulin is administered to patients who have diabetes. These type of patients depend on insulin so their body can use glucose. Therefore, nurses must be familiar with how to mix insulin.

    The goal of this article is to teach you how to mix insulin. Below are a video demonstration and step-by-step instructions on how to do this.

    Miscibility Of Human Semisynthetic Regular And Lente Insulin And Human Biosynthetic Regular And Nph Insulin

    Abstract The miscibility of human semisynthetic regular and lente insulins and human biosynthetic regular and NPH insulins was studied in vitro and in 16 insulin-dependent diabetic patients. In vitro a decrease of regular insulin was found immediately after mixture with semisynthetic lente insulin in proportions 1:4, 1:3, 1:2, 1:1, and 2:1. This was not found after mixture with human biosynthetic regular and NPH insulins. Free insulin and blood glucose were determined over 8 h after the morning injection of regular/lente or regular/NPH insulins in proportions used by the patients mixed in one syringe or in separate syringes. Mixing the regular/lente preparations in one syringe immediately before injection resulted in a significant loss of the early rise in free insulin , with a tendency to a higher free insulin in the afternoon. A corresponding change in the blood glucose profile was seen. No changes were observed in free insulin or blood glucose after mixing regular and NPH preparations compared with separate injections. We conclude that mixing human semisynthetic regular and lente insulins instantly results in a decrease of regular insulin, probably due to formation of a longer-acting preparation, whereas no such changes occur with human biosynthetic regular and NPH insulins .Continue reading > >
