About hydroxocobalamin

Used forAnaemia caused by lack of vitamin B12

Also calledVitamin B12
Available asInjection

Hydroxocobalamin is also known as vitamin B12.

Your body needs vitamin B12 in order to produce red blood cells which carry oxygen around your body. The amount of vitamin B12 in your body is reduced when your gastrointestinal system (gut) does not absorb it properly or if you have had an operation to remove part of your stomach or bowel. When vitamin B12 levels are low, it can cause some types of anaemia which may make you feel tired or short of breath.

Hydroxocobalamin may also be used to treat certain eye conditions.
