B12 Injections

How it Works

Vitamin B12 plays a key role in the normal functioning of the brain and nervous system and in the formation of red blood cells. Lack of B12 can lead to anemia, causing you to feel tired and weak. Our providers are qualified to administer Vitamin B12 injections for patients with a prescription.

  • This injection is provided to you for treatment of conditions not related to pernicious
    anemia. If you have been diagnosed with Pernicious Anemia (a condition wherein the
    body cannot absorb the B12 Vitamin from dairy products or other foods) you will be
    referred to your primary care physician for treatment.
    Be aware that aspirin, aspirin-containing medications (ie: Motrin), fish oil, flax seed,
    high doses of Vitamin A or E, Ginko Biloba, or Garlic may cause undue bleeding which
    may result in bruising. If you wish to minimize the risk of bleeding be advised that we
    recommend you avoid these substances for a minimum of three days prior to injection.
    Eat a meal or light snack prior to treatment. Notify clinician if you have a needle phobia,
    prior to treatment. This allows the clinician to take the appropriate precautions to
    ensure your treatment is as comfortable as possible.
    Optimal results are achieved with clients who continue treatments routinely. Frequency
    will depend on your individual needs/goals as well as your medical history.
    It is normal for the injection site to burn for just a few minutes immediately or shortly
    after the injection. This will dissipate once the muscle is used and the product diffuses
    into the muscle.
    B12 injections do not directly help with losing weight but since B12 vitamins is often
    nicknamed the “energy vitamin” it does stay true to its name in that it should promote
    those who take a vitamin B12 injection into doing more exercise.
    Please call to reschedule if you experience flu-like symptoms or a respiratory infection
    the day prior to treatment. Also, call to reschedule if you notice any type of skin
    condition on the area to be treated.
  • Effects will start to be apparent within several hours to days after treatment.
    Side effects can occur but are often very mild. The most common symptoms are:
    pain/redness or itching at the injection site & mild diarrhea. These side effects will pass
    as time goes by.
    Itching or a feeling of swelling all over the body may occur. If any of these effects
    persist or worsen, tell your doctor promptly. Many people using this medication do not
    have serious side effects.
    This medication may cause low potassium levels in the blood (hypokalemia). Tell your
    doctor immediately if any of these unlikely but serious side effects occur: muscle
    cramps, weakness, irregular heartbeat.
    People who have a rare blood disorder (polycythemia vera) may infrequently have
    symptoms related to this disorder while taking (B12 injections) cyanocobalamin. Seek
    immediate medical attention if any of these rare but very serious symptoms occur:
    chest pain (especially with shortness of breath), weakness on one side of the body,
    sudden vision changes, slurred speech.
    Optimal results are achieved with clients who continue treatments routinely. Most
    patients will receive injections every 2-4 weeks. The frequency of injections will be
    determined between you and your clinician after a full medical history is reviewed.
