This page is only for those patients who have discussed their individual situation with us and we have agreed to continue B12 injections through self-administration only.
If you are not in this group, please see how we will organise B12 for you.
Please read this introductory letter . It provides important safety information.
Please also download this instruction leaflet . You may wish to print it out for ease of reference.
This guide is accompanied by instructional videos at each stage of the injection process.
You or your care-giver are advised to read through the whole process and to watch all the videos first before carrying out your injection.
These are detailed in the introductory letter above, however, you can read them now.
Possible complications of intramuscular B12 injection are as follows:
- Introduction of bacteria under the skin during the injection. It is therefore important that you wash your hands and avoid touching the sterile parts of the needle and syringe during the injection.
- At times the needle can hit a small blood vessel causing a small amount of bleeding under the skin. This causes a bruise to appear which resolves over a few days. To avoid larger bruises, apply moderate pressure to the injection site with cotton wool or gauze for a few minutes after the injection.
- Injecting in the wrong area can cause an abscess to form under the skin. To avoid this only inject in the area recommended by your nurse or doctor. Do not inject into a painful or inflamed area. Seek medical advice if this happens.
- Please note Ivy Grove surgery cannot accept responsibility if the instructions given by your nurse or doctor are not followed and result in injury.
- If you are struggling to follow the instructions in the video or have questions, please do not hesitate to contact us and we will do our best to assist you.
