Subcutaneous Injection Needle Angle: A Comprehensive Guide

When giving a subcutaneous injection, the needle should be inserted at a 45-degree angle to the skin. This angle helps to ensure that the medication is delivered into the subcutaneous tissue, which is the layer of fat between the skin and muscle.

Here are some tips for injecting at a 45-degree angle:

1. Hold the syringe between your thumb and index finger, with the bevel of the needle facing up.

2. Pinch the skin at the injection site with your other hand to create a small tent.

3. Insert the needle at the base of the tent, using a slow, steady motion.

4. Push the needle in until the bevel is just below the surface of the skin.

5. Depress the plunger of the syringe to inject the medication.

6. Withdraw the needle slowly and smoothly.

If you are uncomfortable giving yourself an injection, you can ask a healthcare professional to do it for you.
