Quick Intro

VEI Clinic Apgujeong is an English-friendly internal-medicine clinic in Gangnam offering same-day injections with doctor oversight. We’re on the 3rd floor of Beneheim City, 162 Apgujeong-ro, a short walk from Apgujeong Station (Exit 5).


What Is a Vitamin B12 Shot?

A physician-selected intramuscular (IM) injection of cobalamin to correct low levels and support healthy red-blood-cell and nerve function. We individualize the form (hydroxocobalamin, cyanocobalamin, or—case-by-case—methylcobalamin) and the interval based on your history and labs.


Shots are for diagnosed or suspected deficiency or malabsorption—not a universal “energy booster.”

Who It May Help

  • Documented deficiency/insufficiency on labs (low B12, elevated MMA/± homocysteine)
  • Malabsorption risks: gastric bypass, pernicious anemia, IBD, celiac, chronic gastritis
  • Medication-related: long-term metformin, PPIs/H2 blockers, nitrous-oxide exposure
  • Dietary: vegan/vegetarian patterns without reliable supplementation
  • Neurologic/hematologic symptoms: numbness/tingling, balance issues, glossitis, fatigue, megaloblastic anemia


Evidence & Expectations (Realistic)

  • Correcting deficiency helps anemia and can prevent or improve neuropathy (nerve recovery may take months).
  • If your B12 level is normal, routine injections don’t show reliable energy or cognition benefits. We test first and treat what labs and history support.


Forms & Dosing We Consider

  • Hydroxocobalamin: longer-acting; favored for spaced maintenance in many protocols.
  • Cyanocobalamin: widely used; effective and well-studied.
  • Methylcobalamin: considered selectively; evidence of superiority for most indications is limited.
    Your clinician will choose the agent, dose, and schedule after evaluation.


Safety First

Tell the doctor if you have:

  • History of cobalt/B12 allergy, Leber’s hereditary optic neuropathy, or polycythemia vera
  • Severe kidney or liver disease, or frequent nitrous oxide exposure
  • Current meds (e.g., metformin, PPIs/H2 blockers, chloramphenicol, chemotherapy agents)

Common mild effects: temporary soreness/bruise at the injection site, rare lightheadedness. Very rare: allergic reaction.
 Lab note: Correcting B12 can unmask folate deficiency—we may check both.


Visit Flow (Typically 30–60 Minutes)

  1. Check-in & history → diet, GI history, medications, neuro/hematologic symptoms, allergies.
  2. Baseline labs (or review your results) → CBC, B12, MMA ± homocysteine, ± folate, ± iron panel.
  3. Plan & consent → agent/dose/schedule set; transparent pricing reviewed.
  4. IM injection → quick procedure with after-care guidance.
  5. Follow-up → symptom check + lab re-test in ~8–12 weeks; maintenance plan if indicated.


After-Care Tips

  • Gentle arm movement to reduce soreness
  • Hydrate and eat a balanced meal
  • Keep a symptom diary (energy, concentration, numbness/tingling) weekly
  • If you had severe deficiency, expect gradual improvement and keep your follow-ups


What to Bring

  • Photo ID (passport if visiting)
  • Medication & supplement list (exact doses)

FAQs

How fast will I feel better?
Blood markers may improve within weeks; neurologic symptoms can take months. Early treatment prevents long-term damage.

Do I need pills if I’m getting shots?
Sometimes we use injections to correct levels, then oral maintenance—depends on malabsorption risk and labs.

Can B12 shots help if my level is normal?
Not typically. We avoid unnecessary injections and look for other causes of fatigue (sleep, thyroid, iron, mood, infections, meds).

Is it safe during pregnancy?
B12 is important in pregnancy; dosing should be clinician-guided with labs.

I use nitrous oxide (dental or recreational). Is that relevant?
Yes. Nitrous can inactivate B12 and trigger acute neurologic issues. Please tell the doctor—urgent evaluation may be needed in some cases.
