Insulin-Drawing Techniques

Remember: you can always practice with saline!

Collect all your supplies

  • Insulin
  • Syringe
  • Alcohol wipe for tops of bottles
  • Your log book to record your blood glucose and insulin dosage


  • Know the correct insulin dosage before starting.
  • Disinfect! Swab the top of the insulin bottle with alcohol.
  • Mix cloudy (intermediate-acting) insulin vial by gently turning the bottle up and down for 20 times to make sure the insulin gets well mixed. There should be no clumps of insulin in the bottle.
  • Draw up the air for the cloudy insulin and inject into the cloudy bottle.
  • Draw up the air for the clear insulin and inject into the clear bottle.
  • Draw up the clear (short-acting) insulin, get rid of air bubbles and remove the needle.
  • Slowly add the cloudy insulin into the syringe, making extra careful not to push the insulin back into the vial.
  • If you store your insulin vials in the refrigerator, you can warm up the insulin by holding the filled syringe in the palm of your hand for 1-2 minutes. This will take the sting out!
  • Your insulin is now ready.
