What is cyanocobalamin injection ?
Cyanocobalamin is used to treat vitamin B12 deficiency in people with pernicious anemia and other conditions.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
What is the most important information I should know about cyanocobalamin injection?
You should not use this medicine if you are allergic to cobalt, or if you have Leber's disease.
What should I discuss with my healthcare provider before using cyanocobalamin injection?
You should not use this medicine 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 cyanocobalamin injection is safe for you, tell your doctor if you have:
- cold or allergy symptoms that affect your nose (sinus congestion, sneezing);
- 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.
Cyanocobalamin can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
How is cyanocobalamin injection given?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Cyanocobalamin injection is injected into a muscle or under the skin. You may be shown how to use injections at home. Do not self-inject this medicine if you do not understand how to give the injection and properly dispose of used needles and syringes.
Use a disposable needle only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
While using cyanocobalamin injection, you may need frequent blood tests.
Use cyanocobalamin injection regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
Pernicious anemia is also treated with folic acid to help maintain red blood cells. However, folic acid will not treat Vitamin B12 deficiency and will not prevent possible damage to the spinal cord. Use all of your medications as directed.
To treat pernicious anemia, you may have to use cyanocobalamin 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 a recurrence of anemia and irreversible nerve damage.
Store this medication at room temperature away from moisture, heat, and light.
What happens if I miss a dose?
Call your doctor for instructions if you miss a dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while using cyanocobalamin injection?
Avoid drinking large amounts of alcohol while you are being treated with cyanocobalamin.
What other drugs will affect cyanocobalamin injection?
Other drugs may interact with cyanocobalamin, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using.
Where can I get more information?
Your pharmacist can provide more information about cyanocobalamin injection.
