What is Vitamin B12?
Vitamin B12 is a man-made form of vitamin B12.
Vitamin B12 is important for growth, cell reproduction, blood formation, and protein and tissue synthesis.
Vitamin B12 is used to treat vitamin B12 deficiency in people with pernicious anemia and other conditions.
Before taking this medicine
You should not use Vitamin B12 if you are allergic to cyanocobalamin or cobalt, or if you have Leber’s disease (an inherited form of vision loss). Cyanocobalamin can lead to optic nerve damage (and possibly blindness) in people with Leber’s disease.
To make sure this medicine is safe for you, tell your doctor if you have:
- eye problems or Leber’s disease (in you or a family member);
- kidney or liver disease;
- iron or folic acid deficiency;
- any type of infection; or
- if you are receiving any medication or treatment that affects bone marrow.
How is Vitamin B12 injection given?
Use Vitamin B12 exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.
Vitamin B12 injection is injected into a muscle or under the skin. A healthcare provider may teach you how to properly use the medication by yourself.
Your dose needs may change if you become pregnant, if you breastfeed, or if you eat a vegetarian diet. Tell your doctor about any changes in your diet or medical condition.
Always follow directions on the medicine label about giving Vitamin B12 injection to a child. Your child’s dose will depend on age, weight, diet, and other factors.
For pernicious anemia, you may have to use Vitamin B12 injection for the rest of your life. Do not stop using the medicine unless your doctor tells you to. Untreated vitamin B12 deficiency can lead to anemia or irreversible nerve damage.
Pernicious anemia is also treated with folic acid to help maintain red blood cells. Folic acid alone will not treat Vitamin B12 deficiency or prevent possible damage to the spinal cord. Use all medications as directed.
You will need frequent medical tests.
Vitamin B12 can affect the results of certain medical tests. Tell any doctor who treats you that you are using Vitamin B12 injection.
Store this medication at room temperature away from moisture, heat, and light.
