What is an Injection ?
An Injection is a method of administering medication into the body using a needle and syringe. Injections are used to deliver a wide variety of medications, including vaccines, antibiotics, hormones, and pain relievers.
Types of injections
There are many different types of injections, each with its own unique purpose. Some common types of injections include:
Intramuscular injections: These injections are given into the muscle. They are often used to deliver large doses of medication or medications that need to be absorbed slowly into the bloodstream.
Intravenous injections: These injections are given directly into the bloodstream. They are often used in emergency situations or to deliver medications that need to be absorbed quickly.
Subcutaneous injections: These injections are given under the skin. They are often used to deliver smaller doses of medication or medications that need to be absorbed slowly into the bloodstream.
Intradermal injections: These injections are given into the dermis, the layer of skin just below the epidermis. They are often used to administer allergy shots or to test for allergies.

Injections are used for a variety of purposes, including:
To deliver medication to the body quickly and efficiently.
