What type of medications are typically given by Z-track injection?

Z-track injection is a technique used to prevent the leakage of irritating or staining medications into the subcutaneous tissue, which can cause discomfort and skin staining. This method involves pulling the skin to one side before inserting the needle, which creates a ‘zigzag’ pathway for the medication. Once the medication is injected and the needle is withdrawn, the skin is released, sealing the medication in the muscle and minimizing irritation to the surrounding tissues.

Irritating medications, such as certain iron preparations or other injectables that can cause tissue damage or discoloration, are specifically suited for this technique. By employing the Z-track method, healthcare professionals can ensure that the medication is delivered effectively while reducing potential side effects related to tissue irritation.

Other types of medications, such as vaccines or non-irritating solutions, do not require this technique, as they do not risk causing significant local irritation or damage.
