The Nurses Corner, all about vitamin B12 injections

  1. How do you know if you have MTHFR mutation that causes B12 deficiency?

    MTHFR (or methylenetrahydrofolate reluctase, if you want the complicated version!) is a type of gene that helps produce the MTHFR enzyme. This enzyme is responsible for breaking down a common amino acid found within our blood - homocysteine.

    MTHFR mutations can lead to the enzyme’s inability to effectively break down homocysteine. High levels of homocysteine within the body can lead to a number of health issues, such as vitamin B12 deficiency and heart disease

    This means it’s sometimes recommended that people undergo testing to see whether they have a MTHFR mutation. The test is usually ordered by a doctor when it is discovered that a patient:

    • Has elevated homocysteine levels
    • Has a family history of conditions relating to the heart and blood, such as cardiovascular disease or thrombosis

    B-12 injections are often given in the arm and especially, in medical terms, the deltoid part of the shoulder.

    Cautions and Tips for Proper Injecting

    Throughout my many years as a nurse I picked up quite a few helpful tips to alleviate my patients anxieties and minimize their discomfort. I also self-inject and found these tips helpful for myself, so I wanted to share them with you.

    1. Take caution if you only use one needle to withdraw and inject your B-vitamins. Needle tips are very fragile, and they can easily be bent or dulled with just one use such as withdrawing your vitamins. The slightest bump to the side of an ampule or vial can damage the needle tip.
