There are four primary types of injections:
- Intravenous (IV) injections: This is the fastest method for delivering medication, as it involves directly injecting a medication into a vein using a syringe.
- Intramuscular (IM) injections: These injections are delivered directly into a muscle, allowing for the absorption of medication at a faster rate than subcutaneous injections.
- Subcutaneous (SC) injections: These injections are administered just beneath the skin, allowing for slower absorption of medication compared to IM injections.
- Intradermal (ID) injections: This type of injection is administered into the top layer of skin, primarily used for allergy testing or vaccinations.
These injection types are commonly used in various medical contexts, including treatment, vaccination, and diagnostics.
