What this medicine is used for
Cobalamin deficiency may exist that is unable to be corrected by oral intake and in these cases parenteral administration may be preferable. Oral administration of vitamin B12 may be insufficient in pernicious anaemia, malabsorption disorders, gastrectomy and gastrointestinal pathologies. Specific indications may include: 1. pernicious anaemia as a result of in situ B12 deficiency. In pernicious anaemia co-methylcobalamin is disproportionately reduced in relation to other cobalamins. 2. As an adjunct to the treatment of peripheral neuropathies and diabetic polyneuropathy.
