MIC + B12 Injection — Safety Information

‍

Overview

MIC + B12 injections are compounded prescription medications that combine methionine, inositol, and choline (the “MIC” lipotropic agents) with vitamin B12 (methylcobalamin or hydroxocobalamin). These compounds play supportive roles in liver function, metabolism, and energy processes within the body.
This injection is formulated for intramuscular (IM) or subcutaneous (SubQ) administration under the supervision of a licensed clinician.

Consult Your Healthcare Provider

Always inform your primary care provider and all other healthcare professionals about every prescription, over-the-counter medication, and supplement you take.
This helps prevent drug interactions and ensures coordinated, safe care.

Warnings and Precautions

• Do not use if you have a known allergy to cobalamin (vitamin B12), methionine, inositol, or choline.
  
  
• Use caution if you have liver disease, kidney impairment, or gout, as methionine metabolism can influence homocysteine levels.
  
  
• Safety during pregnancy or breastfeeding has not been established; use only under medical supervision.
  
  
• Injections should be administered by or under the direction of a licensed clinician using sterile technique.
  
  

Drug Interactions

• Chloramphenicol, certain antibiotics, or methotrexate may interfere with the effectiveness of vitamin B12.
  
  
• Levodopa (used for Parkinson’s disease) may interact with B vitamins, potentially altering its effects.
  
  
• Alcohol and chronic use of certain acid-reducing medications can affect vitamin B12 absorption and metabolism.
  
  
• Provide your clinician with a complete list of all medications, supplements, and vitamins you take.
