Vitamin B12 Summary

Methylcobalamin is a form of vitamin B12 used to boost red blood cell production, treat B12 deficiency, and manage dementia symptoms. It should be taken daily as prescribed, and interactions with certain medications like metformin and proton pump inhibitors should be avoided. Missed doses should be handled carefully, and the medicine must be stored in a cool, dry place below 25°C. 

The RDA is 2.8 mcg for adults and 1.8 mcg for children. Natural sources include apples, bananas, oranges, beetroot, mushrooms, and potatoes. Common side effects may include headache, nausea, diarrhea, fatigue, and tingling in the hands and feet. 

Vitamin B12 Uses

This medicine is used to stimulate red blood cell production, treat vitamin B12 deficiency, and help manage symptoms of dementia. 

Directions for use

  1. Take this medicine exactly as prescribed by your doctor, regularly at the same time each day. 
  2. Do not stop taking medication without your doctor’s approval, even if you feel better. 
  3. If you forget to take the medicine, take it as soon as you remember, unless it’s almost time for the next one, then just skip it. 

How Methylcobalamin Works

Vitamin B12 is an essential component for DNA formation in red blood cells (RBCs). A cobalamin deficiency leads to improperly formed RBCs, resulting in a reduced lifespan and anemia.

  1. Vitamin C/Ascorbic acid 
  2. Metformin
