What are the different types of injections?
The four most frequently used types of injection are:
1. Intravenous (IV) injections
An IV injection is the fastest way to inject a medication and involves using a syringe to inject a medication directly into a vein.
2. Intramuscular (IM) injections
IM injections are given deep into a muscle where the medication is then absorbed quickly by surrounding blood vessels.
3. Subcutaneous (SC) injections
SC injections are injected under the skin
4. Intradermal (ID) injections
ID injections are given directly into the middle layer of the skin called the dermis. This type of injection is absorbed more slowly again than IV, IM or SC injections.
Other types of injections include:
Intra-articular injections - into a joint
Peri-articular injections - into the soft tissue close to a joint
Intraosseous injections - into the bone marrow
Intradetrusor injections - into the muscle in the wall of the bladder
Intraocular (intravitreal) injection - into the jelly-like fluid in the eye
Intraperitoneal injections - given within the abdominal cavity
Intracardiac injections - into the muscle or ventricles of the heart
Intracavernous injections - into the base of the penis
