1. Understand the prescribed dose of insulin.
2. Hold the syringe with the cap facing downward. Remove the cap.
3. Air should be drawn into the syringe corresponding to the dose of insulin.
4. The vial is prepared by rolling it between the palms to thoroughly mix the insulin.
5. The vial is then pierced at the rubber portion with the syringe and air is inserted corresponding to the units of insulin to be taken in the vial.
6. With the syringe in the vial, the vial is turned upside down and the piston/plunger is pulled to draw the corresponding amount of insulin into the syringe.
7. The patient then has to clean the skin with an alcohol swab and hold the syringe like a pencil in the right hand.
8. The skin is pinched with the left hand and the needle is fully inserted into the skin.
9. Insulin is then administered by pushing the plunger down using a finger.
10. After fully administering the insulin, a count of 1-10 must be taken before withdrawing the syringe.
11. The syringe is then recapped and kept aside to be used a few more times before it becomes blunt and the pain felt.

This method of deliverance has few advantages and disadvantages:

Advantages:

• It is cheap.
• Its usage is easy to understand especially by the less educated people.
• It can be used by the blind too. This can be done by someone filling the syringes and the patient injecting it at the desired time.

Disadvantages:

• It is uncomfortable to use in parties or get-togethers
• It is more painful to use when compared to other devices such as insulin pens as the syringe needles are slightly thicker than pen needles.
• The procedure is slightly elaborate and time consuming when two types of insulin are required to be mixed and taken.
