What gauge needle is recommended for subcutaneous injections?

The recommended gauge needle for subcutaneous injections is typically in the range of 23 to 25 gauge. This gauge size is ideal because it strikes a balance between being large enough to allow for the easy passage of medication while still being small enough to minimize discomfort for the patient.

A needle that is too large, such as those in the range of 15-18 gauge, would be inappropriate for subcutaneous injections as they can cause excessive tissue trauma and discomfort. Similarly, while options in the 21-23 gauge range are acceptably used, particularly for certain softer tissues, they may not be as effective or comfortable as using a finer gauge for routine subcutaneous injections.

On the other hand, needle sizes in the 27-30 gauge range are generally too fine for subcutaneous injections. These sizes are often used for more delicate tasks, such as insulin injections, where the goal is to minimize pain and tissue disruption. Consequently, utilizing a 23-25 gauge needle ensures a balance, making it well-suited for subcutaneous administration while maintaining patient comfort.
