Hydroxocobalamin-Injektion

About hydroxocobalamin

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.

Before having hydroxocobalamin

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start having hydroxocobalamin injections it is important that your doctor knows:

• If you are pregnant or breastfeeding. (Hydroxocobalamin is not known to be harmful to an unborn baby or while breastfeeding, but nevertheless you should let your doctor know about this.)

• Wenn Sie schon einmal eine allergische Reaktion auf ein Arzneimittel hatten.

• Wenn Sie andere Arzneimittel einnehmen. Dazu gehören alle Arzneimittel, die Sie einnehmen und die rezeptfrei erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

How your hydroxocobalamin is given

• Hydroxocobalamin will usually be given to you by your doctor or nurse. It will be given by injection into a muscle.

• When you first start treatment, you will need to have an injection every 2-3 days. This is to top up the store of vitamin B12 in your body. After a few weeks, you will only need to have one injection every 2-3 months. Your doctor will tell you when to arrange an appointment for you to have these injections. If ever you miss an appointment, you should contact your doctor's surgery to make another appointment as soon as possible so that you receive your injections on time.

Das Beste aus Ihrer Behandlung herausholen

• Before you start this treatment, ask to read the manufacturer's printed information leaflet from inside the pack. The leaflet will give you more information about treatment with hydroxocobalamin.

• Try to keep your regular doctor's appointments so that your progress can be checked. You may need to have some blood tests from time to time, particularly at the beginning of your treatment. The tests will check that the treatment is working, and will also check on the amount of potassium in your blood, as this may drop a little initially.
