How to Give a Z Track Injection

Using the Z track technique to give an intramuscular injection is a safe way to keep medication in the muscle. It also minimizes irritation. But it is not recommended for subcutaneous or intravascular injections. It should be used only if your healthcare provider says it is safe for the medications you are given.

For a Z track injection, your needle should be about 1 - 1.5 inches long. It is inserted at a 90 degree angle into the skin. Your dominant hand holds the syringe barrel while your non-dominant hand stabilizes the needle.

After insertion, the syringe should be held between your thumb and forefinger. This prevents the needle from moving and causing accidental displacement of medication.

After injecting, a 10-second hold time is required to ensure the full dose is received. If you feel that the needle hasn't gotten all the way into the muscle, you should remove it.

If you are giving an injection at home, ask your healthcare provider about the best technique. It should take less than two minutes. If you notice any unusual side effects, such as swelling or redness, tell your doctor right away.

When you are giving a Z-track injection, you should never massage the injection site. This will cause the skin and muscle layer to move and disrupt the needle track. The skin and muscle layer will then close off the hole left by the needle.

Z-track injections are not recommended for infant vaccinations because the skin can become compressed. They are also not suitable for hardened or bruised skin. It is important to cover the injection site with an adhesive bandage.
