- 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 systematically — 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.
