Insulin Injecting Technique

  1. Check the expiry date of the cartridge before buying.
  2. Check the prescription for your insulin dose.
  3. Every time you inject yourself, first wash your hands and allow it to dry naturally.
  4. Remove the insulin pen stored in butter compartment of the refrigerator with cartridge inserted, 30 mins before injecting.
  5. Always work on a table, or seated on a smooth floor.
  6. Take empty insulin pen in your hand and remove the pen cap.
  7. Remove cartridge holder.
  8. Insert the cartridge, in the cartridge holder and lock the holder with the pen.
  9. Clean the rubber cap of the cartridge with alcohol swab. Remove the excess alcohol from the swab every time.
  10. Rotate the pen 10 times in the palm gently and shake the pen gently 10 mins.
  11. Remove the protective cover from the needle and screw it onto the pen.
  12. Remove both the plastic outer cap and inner needle cap.
  13. Throw away the plastic outer cap and keep the inner needle cap safely in the pen holder.
  14. In case the inner cap falls on the ground, discard the needle and use a new one.
  15. Look at the dose window and turn the dosage knob to 2 units. Hold the pen with the needle pointing upwards  & press the button until a drop of insulin appears. This is called as priming and has to be done once for every new needle inserted.

16. Dial the number of units you need to take, as mentioned in the prescription.
17. Mark the injection site on the thing and abdomen.
18. For thigh: Touch both thigh and mark the inner sides. Leave 3 fingers from the knee and mark 3 lines vertically and 7 horizontally at the distance of 2 fingers each.


19. For Abdomen, go 3 fingers above the groin and mark 3 vertical lines at the distance of 2 fingers and 7 horizontal lines at the distance of 2 fingers.



While Injecting:

  1. Mark the site and clean the site downwards using alcohol swab and allow it to dry.
  2. To hold the pen, wrap your finger around the pen with the thumb reaching the dose knob.
  3. Take a large pinch of skin and place the needle at 90 degree.
  4. Push the needle softly and release the Pinch.
  5. Count 1 to 10 to ensure full dose of insulin is released.
  6. Slowly remove the needle and cap it.
  7. Always cap the needle, holding the cap in the palm of your hands.
  8. In case you bleed when the needle comes out, place a cotton swab over it, but do not press or rub the skin.

Insulin Storage: Do not freeze insulin. Do not store insulin in sunlight or in area like window seal, car desk board. Take insulin onboard with you in a coolant pouch when traveling by airplane. Do not put insulin into luggage that will be stored away from you.

Insulin Pens: Store unopened insulin pens/cartridges in the refrigerator in the butter compartment at a temperature of about 4.45 C until the expiration date listed on the pen. Opened pens can be stored at room temperature, but not above 30 C for maximum 30 days and if refrigerated then can be stored for 3 months.

Repeated insulin injections in the same location can cause fat and scar tissue to accumulate causing hard discolored bumps under the skin at the injecting site & is called as lipohypertrophy. These lumps can interfere with insulin therapy. The mass of tissue may slow your absorption of insulin, causing up and down in blood glucose. Later, the delay can cause your glucose levels to become dangerously low or high. Lipohypertrophy makes diabetes disease management more difficult.
