What type of medication is administered with a 20-25 gauge syringe?

A 20-25 gauge syringe is typically utilized for administering aqueous medication. The gauge of a needle indicates its thickness, with a higher gauge number representing a thinner needle. Aqueous medications, which are water-based solutions, can be administered through these needles because they flow easily and can be injected without difficulty.

Oil-based medications, on the other hand, usually require a larger gauge needle, such as a 18 or 19 gauge, due to their thicker consistency. Oral medications do not require any syringe or needle for administration, as they are administered by mouth. Topical medications are applied directly to the skin and similarly do not involve the use of a syringe. Thus, the use of a 20-25 gauge syringe is most appropriate for aqueous medications.
