Intramuscular injection, often abbreviated IM, is the injection of a substance into a muscle. In medicine , it is one of several methods for parenteral administration of medications. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than ...
Hypodermic needles are normally made from a stainless-steel or Niobium tube [17] through a process known as tube drawing where the tube is drawn through progressively smaller dies to make the needle. The end of the needle is bevelled to create a sharp pointed tip, letting the needle easily penetrate the skin. [18] A hypodermic needle tip under ...
A syringe being prepared for injection of medication. An injection (often and usually referred to as a "shot" in US English, a "jab" in UK English, or a "jag" in Scottish English and Scots) is the act of administering a liquid, especially a drug, into a person's body using a needle (usually a hypodermic needle) and a syringe.

Jet injectors were used for mass vaccination, and as an alternative to needle syringes for diabetics to inject insulin. However, the World Health Organization no longer recommends jet injectors for vaccination due to risks of disease transmission. [1] Similar devices are used in other industries to inject grease or other fluid.
It is designed with a luer-lock device to accept a sterile hypodermic needle or to be linked directly to intravenous tubing line. The product can deliver an intravenous or intramuscular injection by means of a holder which attaches to the barrel and plunger to the barrel plug. Medication is prefilled into the syringe barrel.
The term injection encompasses intravenous (IV), intramuscular (IM), subcutaneous (SC) and intradermal (ID) administration. [35] Parenteral administration generally acts more rapidly than topical or enteral administration, with onset of action often occurring in 15–30 seconds for IV, 10–20 minutes for IM and 15–30 minutes for SC. [36]
"Tuberculin" syringes and types of syringes used to inject insulin are commonly used. Commonly used syringes usually have a built-in 28 gauge (or thereabouts) needle typically 1/2 or 5/8 inches long. The preferred injection site is the crook of the elbow (i.e., the Median cubital vein), on the user's non-writing hand.
She preferred hypodermic needles because of their strength and tactile feedback: "A 22-gauge, 3.8-cm (1.5-in) needle is usually suitable for most superficial muscles. In hyperalgesic patients, a 25-gauge, 3.8-cm (1.5-in) needle may cause less discomfort, but will not provide the clear feeling of the structures being penetrated by the needle and ...
