This medicine contains cyancobalamin vitamin B12, which is used for the treatment of pernicious anaemia, and nutritional deficiencies of vitamin B12 which results in macrocytic anaemia.
The absorption of cobalamins from the gut is dependent upon the glycoprotein intrinsic factor. Cobalamins are transported rapidly into the blood bound to protein, known as transcobalamins. Cobalamins are stored in the liver and excreted in the bile. They are known to cross the placenta.
For pernicious anaemia, an adequate dose must be used and the blood picture must be examined regularly at least every 3 months for 18 months until stabilised, and then annually.
