What should I watch for while taking Cyanocobalamin? (Back to top) Unless you have pernicious anemia or a condition where you cannot absorb cyanocobalamin, make sure you have a proper diet. Having vitamin supplements is not a substitute for a healthy diet. Foods that contain vitamin B12 include fish, seafood, egg yolk, milk and fermented cheeses. There is no Vitamin B12 in any vegetables; therefore, strict vegetarians are at an increased risk of vitamin B12 deficiency.

Treating yourself with large doses of cyanocobalamin can be unsafe. Do not treat yourself without your prescriber's advice. Certain factors can increase your chance of getting vitamin B12 deficiency. These include some infections or other illness, periods of stress, genetic disorders, patients who smoke or those with a high alcohol intake. Restrict your alcohol intake and avoid smoking to get the best benefit. Where can I keep my medicine? (Back to top) Keep out of the reach of children.
