Cobalin -H Hydroxocobalamin (5x1ml)
The most common cause of vitamin B12 deficiency in the UK is a condition called pernicious anaemia. This is a condition where insufficient amounts of vitamin B12 are absorbed into your body from the food you eat.
This can be because you are not able to absorb it properly, or because you have had surgery which has removed part of your digestive system. This type of anaemia is easily treated by having regular injections of hydroxocobalamin, which is a form of vitamin B12.
Hydroxocobalamin is also occasionally used for some rare eye conditions.
