Vitamin B12 Injections

These injections may help if you are suffering from any of the symptoms listed below. This list is not meant as a diagnosis and a doctor should be consulted if there are any concerns.

B-12 deficiency risk factors Both diabetes and some medications for type 2 diabetes can increase the risk of vitamin B-12 deficiency.

  • Also, the following risk factors can increase the chance of developing vitamin B-12 deficiency:

    •       alcohol abuse
    •       smoking
    •       certain prescription medications, including antacids and some type 2 diabetes drugs
    •       having an endocrine-related autoimmune disorder, such as diabetes or a thyroid disorder
    •       eating a vegetarian or vegan diet
    •       certain gastrointestinal disorders, such as Crohn’s disease
    •       gastric bypass or the removal of parts of the stomach
    •       aging

  • Some common signs and symptoms include:

    • decreased cognitive function, such as issues with memory or understanding
    • fatigue
    • lethargy
    • constipation
    • feeling faint
    • depression or irritability
    • headache
    • difficulty maintaining balance
    • sore, swollen tongue, which may be pale yellow or very red
    • heart palpitations
    • mouth ulcers
    • paraesthesia (pins and needles)
    • vision changes

  • People with gastrointestinal issues

    A gastrointestinal tract that does not function normally may inhibit vitamin B-12 release or absorption. For this reason, people with disorders such as celiac disease and Crohn’s disease may be at higher risk of vitamin B-12 deficiency.
    Individuals who have undergone gastrointestinal surgery, including weight loss surgery, may have less of the cells necessary to secrete stomach acid and intrinsic factor. As a result, they may struggle to absorb B-12.

    Vitamin B-12 shots, rather than oral supplements, may be particularly helpful for people who have gastrointestinal issues because injections tend to bypass these areas.

  • Vegetarians and vegans

    As vitamin B-12 is found mainly in fish, meat, eggs, and dairy, people who do not consume these foods are at risk of B-12 deficiency and may benefit from regular B-12 shots or other supplements.

  • Drug interactions

    Vitamin B-12 may interact with certain medications. People must always inform their doctor about all prescription and over-the-counter drugs they are taking before receiving a B-12 shot.

  • Allergy and medical conditions

    Those who have allergies or medical conditions should always inform their doctor before receiving a B-12 shot.

  • Risks

    Swollen ankles or feet are a potential side effect of vitamin B-12 shots, and require immediate medical attention.

    There is no upper limit for the intake of vitamin B-12 because the risk of toxicity or overdose is extremely low. However, B-12 shots may have other side effects.

  • Mild side effects and potential risks, which should be referred to a doctor if they persist or worsen, include:

    •       pain, redness, or itching at the site of the injection
    •       mild diarrhea
    •       swelling sensation in the body

    More serious side effects, which require immediate medical attention, include:
    •       muscle cramps
    •       irregular heartbeat
    •       unusual weakness or tiredness
    •       swelling of the ankles or feet

  • Severe reactions are very rare but require emergency intervention. These include:

    •       itching and swelling of the face, throat, or tongue
    •       breathing difficulties
    •       severe dizziness
    •       sudden vision changes
    •       slurred speech

  • Some commonly prescribed medications that may interact with B-12 include:

    •       Aspirin
    •       antibiotics
    •       H2 receptor antagonists
    •       metformin
    •       oral contraceptives
    •       proton pump inhibitors

  • Examples of allergies or conditions that may interact with B-12 shots include:

    • allergy to cyanocobalamin or cobalt
      •       hypokalemia (low potassium levels)
      •       kidney disease
      •       polycythemia vera (a rare blood disorder)
      •       Leber’s disease (an eye disease)
      •       deficiencies in other nutrients, particularly folic acid and iron
