What are the angle recommendations for Subcutaneous (SubQ) injections?

The recommended angle for Subcutaneous (SubQ) injections is typically 45 degrees. This angle allows the needle to penetrate the subcutaneous layer effectively while minimizing discomfort and ensuring proper delivery of the medication into the fatty tissue just beneath the skin. At this angle, there is a balance between reaching the subcutaneous tissue and reducing the risk of injecting into the muscle layer below.

While injections at a 90-degree angle may deliver medication quickly into the muscle and could be appropriate for intramuscular injections, it does not align with the technique for SubQ injections. An angle of 30 degrees may not adequately ensure that the medication is delivered to the correct tissue layer, leading to ineffective administration. Similarly, a 15-degree angle is generally too shallow and could risk hitting the surface of the skin rather than the subcutaneous tissue. Therefore, the 45-degree angle is the ideal choice for SubQ injections.
