- Intermediate-acting insulin: Takes 2 to 4 hours to start working and lasts 12 to 18 hours.
- Long-acting insulin: Gradually works for 24 hours, providing a steady level of insulin.
How to Administer Insulin
Administering insulin can be done in various ways, most commonly through injections. Here’s a simple step-by-step guide:
- Wash your hands thoroughly with soap and water.
- Gather all necessary supplies: insulin vial or pen, alcohol swab, syringe or pen needle.
- If using a vial, roll the insulin bottle gently between your hands to mix it (if required). Do not shake it.
- Clean the rubber top of the vial with an alcohol swab.
- Draw air into the syringe equivalent to your dose of insulin, then insert the needle into the vial and push the air in.
- Invert the vial and pull back the plunger to draw your prescribed dose of insulin.
- Remove the needle and check for air bubbles; if present, tap the syringe to remove them.
- Choose an injection site (usually the abdomen, thigh, or upper arm) and clean it with an alcohol swab.
- Insert the needle at a 90-degree angle and inject the insulin.
- Remove the needle and apply gentle pressure on the site with a cotton ball or gauze.
