How Does It Work?

Anemia is a condition caused by an abnormally low level of red blood cells. The body needs vitamin B12 to produce healthy red blood cells. Therefore, when vitamin B12 levels are low, anemia can develop.
 
Many people with anemia from low vitamin B12 levels (known as pernicious anemia) cannot properly absorb vitamin B12 from the intestines. Therefore, pernicious anemia is often treated with vitamin B12 injections.
 
Cyanocobalamin nasal spray contains a form of vitamin B12 known as cyanocobalamin. It works by supplying extra vitamin B12 to the body. By supplying the body with extra vitamin B12, cyanocobalamin nasal spray can prevent anemia from returning in people who have already been treated with vitamin B12 injections. It can also prevent low levels of vitamin B12 in people who need extra vitamin B12 due to a deficiency in their diet or certain medical conditions that make them more prone to a B12 deficiency.
 
Cyanocobalamin nasal spray is sprayed into the nostril, where it is absorbed through the inner lining of the nose into the bloodstream. Because it is a nasal spray, cyanocobalamin nasal spray can be used in people who cannot absorb the vitamin through the digestive tract.
