Injecting medicine requires careful technique and adherence to specific instructions for the medication and injection type. Improper injection can lead to complications. This information is for general knowledge only and should not be considered medical advice. Always consult a healthcare professional for guidance on administering injections.
Types of Injections
There are several types of injections, each requiring a different technique:
-
Intramuscular (IM) injections: These injections deliver medication into a muscle. The video reference demonstrates rapid injection into the tissue followed by needle withdrawal and pressure application to the injection site. The Roswell Park Comprehensive Cancer Center article mentions inserting the needle at a 90° angle for this type of injection. (https://www.roswellpark.org/cancertalk/202110/giving-yourself-injection)
-
Subcutaneous (SC) injections: These injections place medication under the skin, not into a muscle. The Alberta Health Services page describes subcutaneous shots as injections under the skin, not into the muscle, suitable for medications such as insulin. (https://myhealth.alberta.ca/Health/aftercareinformation/pages/conditions.aspx?hwid=abl4055) The Memorial Sloan Kettering Cancer Center provides guidance on self-administering subcutaneous injections using pre-filled syringes.

-
Intradermal (ID) injections: These are administered just beneath the skin's surface. This method is not detailed in the provided references.
-
Intravenous (IV) injections: These deliver medication directly into a vein. This method is also not detailed in the provided references and requires specialized training.
General Steps (for IM and SC injections, with caveats):
These steps are generalized and might vary depending on the specific medication and injection type:
- Prepare the injection site: Cleanse the area with an antiseptic wipe.
- Prepare the syringe: Ensure the correct medication and dose are in the syringe.
- Insert the needle: The angle of insertion varies depending on the injection type (90° for IM, 45° for SC, generally).
- Inject the medication: Slowly and steadily push the plunger.
- Withdraw the needle: Remove the needle quickly and apply pressure to the injection site with a dry cotton ball or gauze to prevent bleeding.
Important Considerations
- Storage: Medication storage varies. Some medications require refrigeration, while others are stable at room temperature. Always follow the manufacturer's instructions. (https://www.mskcc.org/cancer-care/patient-education/how-give-yourself-subcutaneous-injection-using-prefilled-syringe)
- Specific instructions: Always follow the instructions provided with your specific medication.
- Medical guidance: Never attempt to inject medicine without proper training and guidance from a healthcare professional.
