The needle gauge becomes a consideration when the vein of the patient is narrow, fragile, or superficial. In such cases, a gauge size with a LARGER number (eg, 25 G) may be preferred over a routine needle gauge (eg, 21 G) to minimize damage to the blood vessel, as well as minimize the associated pain with collection.

Why are subcutaneous injections given by a hypodermic needle?

Subcutaneous means under the skin. In this type of injection, a short needle is used to inject a drug into the tissue layer between the skin and the muscle. Medication given this way is usually absorbed more slowly than if injected into a vein, sometimes over a period of 24 hours.

Studies have also shown smaller diameter needle to cause less pain [25]. Authors hypothesize that the smaller 25-gauge needle can be less painful for patients, hence making the procedure more tolerable.
