How does hydroxocobalamin work?
Hydroxocobalamin helps the body absorb and use vitamin B12, which is essential for producing red blood cells and preventing nerve damage.
What is hydroxocobalamin used to treat?
Hydroxocobalamin is commonly prescribed for:
- Vitamin B12 deficiency (caused by poor diet, pernicious anaemia, or absorption problems)
- Pernicious anaemia (a condition where the body cannot absorb vitamin B12 properly)
- Supporting nerve health (in conditions such as neuropathy)
- Cyanide poisoning (in emergency cases)
Who can take hydroxocobalamin?
Hydroxocobalamin is suitable for most adults and children who need vitamin B12 supplementation.
Who might not be able to take hydroxocobalamin?
Hydroxocobalamin may not be suitable if you:
- Have a history of allergic reactions to vitamin B12 injections
- Have low potassium levels (hypokalaemia)
- Have a rare genetic disorder affecting B12 metabolism
Can I take hydroxocobalamin if I’m pregnant or breastfeeding?
Yes, hydroxocobalamin is safe during pregnancy and breastfeeding, and it is often recommended to prevent deficiency.
What if I miss a dose?
If you miss a scheduled injection, take it as soon as possible. If it’s close to your next dose, skip the missed one—do not take extra doses to make up for it.
How effective is hydroxocobalamin?
Hydroxocobalamin is highly effective at raising vitamin B12 levels and preventing deficiency-related symptoms.
What should I do if I take too much?
Taking too much hydroxocobalamin is unlikely to cause harm, as excess amounts are usually excreted in urine. However, if you feel unwell, seek medical advice.
What dose of hydroxocobalamin is usually taken?
- For vitamin B12 deficiency: 1mg injection every 2–3 months (or more frequently if needed)
- For pernicious anaemia: 1mg injection every 2 months
- For cyanide poisoning: Higher doses given in a hospital setting
Your doctor will determine the correct dose based on your condition.
