  • Do not aspirate for subcutaneous injections. Inject slowly and steadily.
  • Wait 5–10 seconds before withdrawing, then apply gentle pressure. Do not rub the site.
  • Rotate sites between the abdomen (at least 5 cm from the navel), thighs and upper arms to avoid lipohypertrophy.
  • Use a new sterile 28–31 G insulin syringe every time and dispose of it in a sharps container.
