<p><b>New page</b></p><div> An '''intramuscular injection''' is a method of administering medication by injecting substances directly into a muscle. It is a common technique used for delivering a variety of medications, including vaccines, hormonal therapies, and certain antibiotics.<br />

== Anatomy and Technique ==<br />
*Intramuscular injections are given into the muscle layer beneath the skin and subcutaneous tissue. Key sites for intramuscular injection include the [[deltoid muscle]] in the upper arm, the [[vastus lateralis]] muscle in the thigh, and the [[ventrogluteal]] and [[dorsogluteal]] muscles in the buttock.<br />
*Proper technique is vital for the safety and efficacy of an intramuscular injection. This includes selecting the correct site and needle length, preparing the site with an alcohol swab, and injecting the needle at a 90-degree angle to the skin's surface. The [[Z-track method]], where the skin is pulled laterally prior to injection, can be used to ensure medication does not leak back along the needle track.<br />
<br />
== Medications Administered ==<br />
Intramuscular injections allow for rapid absorption and onset of action, as well as prolonged duration compared to [[subcutaneous injection]]s. They are typically used for medications that are not suitable for oral administration. This can include certain [[vaccines]], hormonal therapies such as [[testosterone]] and [[contraceptives]], and certain [[antibiotics]] like [[penicillin]].<br />
<br />
== Risks and Complications ==<br />
While intramuscular injections are generally safe, they are not without risks. Potential complications include pain at the injection site, bleeding, and bruising. More severe risks can involve nerve damage if the injection is improperly placed, [[abscess]] formation, and muscle fibrosis with repeated injections.<br />
