Administering a Vitamin B injection in the deltoid muscle is not a difficult task, but does require a bit of knowledge and practice. Vitamin B is given as an intramuscular injection. This means the needle goes directly into the muscle to deliver the medication.

    Preparing the Injection

  1. 1

    Wash hands with soap and warm water. Remove a disposable syringe with attached needle from the wrapper. Remove the lid to the vial of vitamin B.

  2. 2

    Wipe the top of the vial with an alcohol swab. Allow alcohol to dry.

  3. 3

    Remove cap from needle and draw air into the syringe. The amount of air drawn into the syringe should be the exact amount of prescribed vitamin B that will be given. Confirm to be sure the dose of vitamin B being administered. Insert needle into the top of the vitamin B vial and the inject air into the vial.

  4. 4

    Hold thumb against syringe plunger and invert syringe and vial. Now the vial will be in the air and the bottom of the syringe will be pointing down.

  5. 5

    Release pressure on syringe plunger. Slowly allow the medication to enter the syringe. Try to keep air bubbles to a minimum. Once the correct amount of medication is in the syringe, pull the vial off the top of the needle.

  6. 6

    Tap the syringe with fingers to release any air bubbles and carefully expel them from the syringe by slightly pressing on the plunger.

    Administering the Injection

  1. 1

    Wipe the top third of the upper arm with an alcohol swab and allow it to dry.

  2. 2

    Grasp the deltoid muscle between finger and thumb of the non-dominant hand and hold it.

  3. 3

    Hold syringe like a dart with the dominant hand and push the needle into the deltoid muscle. The injection should enter the muscle approximately two finger widths below the shoulder.

  4. 4

    Pull back on the plunger slightly to be sure the needle did not enter a blood vessel. There will be blood entering the syringe during the pull back if a vessel was injured.

  5. 5

    Press the plunger until the medication has entered the muscle. Remove the needle from the arm. Apply pressure to the site with a cotton ball for a minute and apply an adhesive bandage, if needed.

Tips and warnings

  • Injecting into the deltoid muscle of the upper arm is easiest when another individual administers the medication. It is difficult to correctly self inject into the deltoid muscle.
  • If blood appears in the syringe when drawing back, remove the needle and discard the syringe with medication. Begin the process again and inject in a different location.
