Insulin

Insulin is a hormone that lowers blood sugars by moving sugar out of the blood stream and into the cells of the body for energy. It’s produced in the beta cells of the pancreas. Insulin is essential for life.

Rapid/Short Acting Insulin Insulin Name Onset Peak Max Duration Shelf Life (once opened)
Humalog 15 – 30 minutes ½ – 2½  hours 3 – 6½ hours 28 days
NovoLog 10 – 30 minutes 1 – 3 hours 3 – 5 hours 28 days
Apidra 5 – 15 minutes 45 – 75 minutes 2 – 4 hours 28 days
Long Acting Insulin Lantus/Basaglar (pen only) 3 – 4 hours Almost no peak 24 hours 28 days
Levemir 3 – 4 hours Almost no peak 6 – 23 hours 42 days
Tresiba (pen only) 1 hour Almost no peak 42 hours 56 days

There are several different concentrations of insulin. Never use insulin that has NOT been prescribed by your physician. 

How To Use

Initially, the child’s doctor will decide your/your child’s insulin dose.

  • Lantus/Basaglar/Levemir must be given at the same time every day. Tresiba works best when given at the same time every day.
  • Humalog/NovoLog/Apidra work best when given before the meal. §  Do NOT give more frequently than every 2.5 hours.
  • Rapid acting and long acting insulin can be given at the same time of day, but do not inject into the same place on the body.

Storage

  • Keep insulin from extreme heat or cold temperatures (should be 40-85 ̊F).
  • Insulin will not be effective if it freezes (even slightly) and must be thrown away.
  • UNOPENED insulin should be stored in the refrigerator and is good until the printed expiration date.
  • OPENED insulin should be stored at room temperature and is only good for so many days. See above table.

When NOT To Use

  • Do not use Humalog, NovoLog, Apidra, Lantus/Basaglar, Levemir or Tresiba if it looks cloudy, frosty, or if solid particles can be seen.
  • Do not use insulin past the manufacturer expiration date that is printed on the bottle/pen/cartridge.

Additional Information

  • Insulin is measured in “units.”
  • To avoid errors in giving the wrong insulin, put a rubber band around your short acting or long acting insulin.
  • Check the manufacturer and type of insulin before leaving the pharmacy to make sure it is correct.
  • If blood sugars are highly erratic without any clear reason, start a new bottle/pen/cartridge.
  • Do not mix or dilute Lantus or Levemir insulin in same syringes with any other insulin or diluent.
  • Always have back-up insulin available. Avoid having multiple vials/pens/cartridges open at once.

A Guide To Subcutaneous Injections (Shots)

  • Definition

    A subcutaneous injection (shot) is a shot into the tissues just below the outer layer of the skin. The amount of medications for subcutaneous shots is small, no more than 1 mL (milliliter).
  • Getting Medication Ready For The Shot

    • Gather supplies:
      • new syringe
      • vial of medicine
      • alcohol wipes
      • hard plastic container to throw away needles and syringe.
    • Wash hands with soap and water.
    • Use a new alcohol wipe to clean the top of the medication vial for 10 seconds. Allow alcohol to dry.
    • Draw up the prescribed dose of medication into the syringe, as instructed.
  • Preparing Site For Shot

    • Choose a spot on the body for the shot (see picture). The preferred spots are:
      • abdomen
      • top or outsides of the thighs
      • top of the buttocks
      • backs of upper arms
    • Avoid areas that are:
      • bruised
      • have signs of an infection, like redness or swelling.
    • Rotate preferred spots on the body with each shot.
    • Cleanse spot with a new alcohol wipe for 10 seconds.
    • Allow alcohol to dry (about 10 seconds).
  • Giving The Shot

    • With your thumb and first finger, grasp the skin on both sides of the spot that you just cleaned (similar to a pinching position).
    • Hold the syringe like a pencil at a 90-degree angle.
    • Using a quick, smooth motion, insert the entire needle into the skin.
    • Slowly press down on the syringe plunger; release your grasp on the skin.
    • Remove the needle smoothly, pulling out at the same angle as it was inserted.
    • Cover the injection site with a finger for a couple seconds. Avoid using a tissue or cotton ball for this.
    • Do not place the plastic cover back on the needle.
    • Placed the used syringe in a hard plastic container.

A Guide to Subcutaneous Injections (shots) – Insulin Pens

  • Definition

    A subcutaneous injection (shot) is a shot into the fatty tissue just below the outer layer of the skin. The amount of medication for a subcutaneous shot is small.
  • Getting Insulin Ready

    • Gather supplies:
      • New pen needle
      • Insulin pen
      • Alcohol wipes
      • Hard plastic container to throw away pen needles
    • Wash hands with soap and water.
    • Remove insulin pen cap.
    • Use a new alcohol wipe to clean the top of the insulin pen for 10 seconds. Allow alcohol to dry.
    • Remove the paper cover on the sterile pen needle. A new needle should be used with each injection.
    • Gently screw the pen needle straight onto the top of the insulin pen.
    • Remove the clear cover and then remove the smaller colored cover.
    • Prime the needle to ensure it is working properly.
      • Turn the dial on the bottom of the pen to 2 units, press and hold the dial until insulin comes out of the needle. Repeat until you see insulin come out of the needle tip.
      • If insulin is not seen after the 3rd attempt, put the
        clear plastic cap back on the pen needle, twist the
        pen needle to remove it from the pen and throw it
        away in a hard plastic container.
      • Get a new pen needle and repeat the above steps.
      • Once insulin is seen coming out of the tip of the pen needle, the needle is primed.
    • Priming MUST be done before every injection.
    • Once the insulin pen is primed, dial the prescribed or calculated dose of insulin into the pen.
  • Preparing The Site For A Shot

    • Choose a spot on the body for the shot (see picture). The preferred spots are:
      • Abdomen
      • Top or outsides of the thighs
      • Top of the buttocks
      • Backs of upper arms
    • Avoid areas that are:
      • Bruised or
      • Have signs of an infection, like redness or swelling.
    • Rotate preferred spots on the body with each shot.
    • Cleanse spot with a new alcohol wipe for 10 seconds.
    • Allow alcohol to dry (about 10 seconds).
  • Giving The Shot

    • With your thumb and first finger, grab the skin around the spot that you just cleaned and pinch your fingers together.
    • Hold the syringe like a pencil at a 90-degree angle.
    • Using a quick, smooth motion, insert the entire needle into the pinched skin between your thumb and first finger.
    • Slowly press and hold down on the insulin pen dial, once the insulin pen dial returns to zero, count to 10 slowly.
    • Release your pinch on the skin, remove the needle smoothly, pulling out at the same angle as it was inserted.
    • Cover the injection site with a finger for a couple seconds. Avoid using a tissue or cotton ball for this.
    • Place the clear plastic cover back on the needle.
    • Twist the pen needle to remove it and place it in a hard plastic container.

    Insulin pens are for individual use only and are not to be shared.
