Could I be allergic to vitamin B12 injections, and what are the signs to watch out for?

While rare, allergic reactions to vitamin B12 injections are possible. Here’s what you need to be aware of:

  • Types of Allergies:
    • True B12 (cobalamin) allergy is uncommon.
    • Reactions to other ingredients in the injection, like preservatives, are more likely.
  • Signs of an Allergic Reaction:
    • Skin Reactions: Rash, hives, itching, swelling (especially of the face, tongue, or throat)
    • Respiratory Issues: Difficulty breathing, wheezing, tightness in the chest
    • Gastrointestinal: Nausea, vomiting, diarrhea
    • Cardiovascular: Dizziness, lightheadedness, rapid heart rate
    • Anaphylaxis: This is a severe, life-threatening allergic reaction that requires immediate medical attention.

What to Do:

  • Inform Your Provider: Before your injection at House of Aesthetics, mention any history of allergies, especially to medications or ingredients like cobalt.
  • Monitor for Reactions: After your injection, be vigilant for any signs of an allergic reaction, even mild ones.
  • Seek Help: If you experience any concerning symptoms, contact House of Aesthetics or seek medical attention immediately.

Important Note: Even if you’ve had previous B12 injections with no issues, it’s still possible to develop an allergic reaction over time.
