What are different gauge needles used for?
The length of a needle is listed after the gauge number. For example, 25G ½ refers to a 25 gauge, ½ inch-long needle. Longer needles (½ inch or longer) are commonly used for intramuscular injections, while shorter (shorter than ½ inch) needles are more often used for intravenous injections.
Can you inject with an 18 gauge needle?
SUBCUTANEOUS INJECTION For subcutaneous injections, a 1-cc syringe and 27 gauge (5/8″) needle may be used for injecting. The amount of diluent used is 1 mL for up to 6 ampules of drug. Use an 18-gauge 1½” needle for mixing and replace with original needle (27 gauge) on syringe for injecting.
What is the smallest gauge needle for injections?

These are regular-walled medical point needles. They are for intramuscular, subcutaneous, and other injections and are available in a wide range of gauges and lengths.
How big is a 13 gauge needle?

What are 18 gauge needles used for?

Can you use a 20 gauge needle for IM injections?
Intramuscular injections go directly into a muscle. 7 Muscle is deeper than the subcutaneous layer of skin, so the needle used for intramuscular injections must be thicker and longer. 20 or 22 G needles that are an inch or an inch-and-a-half-long are usually best.
