Subcutaneous Injection Technique

A subcutaneous (subQ) injection involves injecting medication into the fatty tissue layer under the skin, typically at a 45-90 degree angle, after pinching the skin to ensure the needle enters the subcutaneous layer. 

Step 1. Preparation:

• Clean the injection site: Clean the area with an alcohol swab and allow it to dry completely. 
• Select the injection site: Common sites include the outer upper arm, abdomen, or thigh, ensuring you rotate injection sites to avoid irritation. 
• Prepare the medication: Ensure the medication is at room temperature, and check the expiration date. 

Step 2. Injection Technique:

• Pinch the skin: Use your non-dominant hand to pinch a 1-2 inch fold of skin at the injection site. 
• Insert the needle:
  • 45-degree angle: For shorter needles, insert the needle at a 45-degree angle into the pinched skin.
  • 90-degree angle: For longer needles, insert the needle at a 90-degree angle (perpendicular) into the pinched skin. 
  •  Inject the medication: Slowly push the plunger to inject the medication. 
• Withdraw the needle: Remove the needle quickly and gently at the same angle it was inserted. 
• Apply gentle pressure: Gently apply pressure to the injection site with a clean gauze pad / alcohol swab for a few seconds to stop any bleeding if any.

Step3. Post-Injection:

• Dispose of the needle: Immediately place the needle and syringe in a sharps container.
• Wash your hands: Wash your hands thoroughly with soap and water.
• Monitor for any adverse reactions: Be aware of any signs of infection or allergic reaction and seek medical attention if needed.
