Generic Name: cyanocobalamin nasal (Pronunciation: sigh ah no ko BALL ah min)

What is cyanocobalamin nasal (Nascobal)?

Cyanocobalamin nasal is a synthetic (man-made) form of vitamin B12. Vitamin B12 is important for growth, cell reproduction, blood formation, and protein and tissue synthesis.

Cyanocobalamin nasal is used to maintain vitamin B12 levels in patients with pernicious anemia, nutritional vitamin B12 deficiency, malabsorption of vitamin B12, and other cases of vitamin B12 deficiency.

Cyanocobalamin nasal may also be used for purposes other than those listed in this medication guide.

If you experience an allergic reaction (difficulty breathing; closing of your throat; swelling of your lips, tongue, or face; or hives), stop using cyanocobalamin nasal and seek emergency medical attention:

Other, less serious side effects may be more likely to occur. Continue to use cyanocobalamin nasal and talk to your doctor if you experience

headache;
runny nose;
upset stomach; or
numbness or tingling.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.

What is the most important information I should know about cyanocobalamin nasal (Nascobal)?

To treat pernicious anemia, you will have to use this medication on a regular basis for the rest of your life. Failure to do this will result in irreversible damage to the nerves of your spinal cord.

Use the nasal spray one hour before or after eating or drinking hot foods or liquids.
