Intramuscular injection is commonly used for medication administration. Medication administered in the muscle is generally quickly absorbed in the bloodstream, and avoids the first pass metabolism which occurs with oral administration. [1]
Intradermal injections are most commonly used for sensitivity tests, including tuberculin skin tests and allergy tests, as well as sensitivity tests to medications a person has never had before. The reactions caused by tests which use intradermal injection are more easily seen due to the location of the injection, and when positive will present ...
However, in common English the term has mostly been used to describe the four most well-known routes of injection. A peripheral IV placed on the hand. A medical professional performs an intradermal (ID) injection. The term injection encompasses intravenous (IV), intramuscular (IM), subcutaneous (SC) and intradermal (ID) administration. [35]
There are many possible routes for an injection, with intramuscular (into a muscle) and intravenous (into a vein) being the most common. A hypodermic syringe has the ability to retain liquid and blood in it up to years after the last use and a great deal of caution should be taken to use a new syringe every time.
"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

Intravenous or intramuscular injections in hypotensive people or those in shock is administered carefully and vital signs are closely monitored. [ 61 ] Benzodiazepines such as diazepam are lipophilic and rapidly penetrate membranes, thus rapidly cross over into the placenta with significant uptake of the drug.
Designs exist for both intramuscular and subcutaneous injection. Disposable autoinjectors commonly use a pre-loaded spring as a power source. This spring and the associated mechanical components form a one-shot linear actuator. [citation needed] When triggered the actuator drives a three-step sequence: [citation needed]
