Do you also feel tired all the time, feel weak, and have difficulty concentrating? Maybe your hands and feet are tingling, or you have mouth ulcers? One of the reasons for many of these symptoms could be a low level of vitamin B12 in your body. So, a special treatment that doctors recommend in times like these is a shot called Hydroxocobalamin. Today, we will talk about everything very simply.
Simply put, what is hydroxocobalamin?
Hydroxocobalamin is a form of vitamin B12. It is given as an injection. Vitamin B12 is essential for several very important functions in our body.
- Nervous system health: Vitamin B12 is essential for our nerves to function properly and transmit messages. When it is low, things like numbness in the limbs and memory loss occur.
- Red blood cell production: The red blood cells in our blood carry oxygen throughout the body. They need vitamin B12 to make them properly. When B12 is low, red blood cell production is impaired, leading to anemia. This is when things like extreme fatigue and paleness occur.
We usually get vitamin B12 from the foods we eat (especially animal foods like meat, fish, milk, and eggs). But some people's bodies are unable to absorb this vitamin from food. Or, those who eat only vegetarian foods do not get enough B12. That's why this hydroxocobalamin injection is given to such people.
Things you need to tell your doctor before getting this vaccine
Before giving you this vaccine, your doctor will need to know your complete health history. Therefore, if you have any of the following conditions, be sure to tell your doctor .
| Health condition or fact | Why is that important? |
|---|---|
| High blood pressure | Sometimes medication can affect blood pressure. |
| Various anemia conditions (e.g. Iron-deficiency anemia, Megaloblastic anemia) | It is important to know the exact cause of anemia and treat it. |
| Kidney disease | Because medications are eliminated from the body through the kidneys, it is important to be aware of kidney function. |
| Decreased folic acid in the blood | Both B12 and folic acid are needed to make red blood cells. If you are deficient in one, you need to take care of the other as well. |
| Allergies (Especially for hydroxocobalamin, cyanocobalamin, cobalt, other medicines, foods, or preservatives) | This is essential to prevent serious allergic reactions. |
| Being pregnant or trying to get pregnant | It is mandatory to seek medical advice before taking any medication during pregnancy. |
| Breastfeeding the baby | The doctor should be aware of whether the medication passes to the baby through breast milk or not. |
How is this vaccine used?
This is not a medicine you can take at home. Hydroxocobalamin is an injection that is given into a muscle or a vein . So it is usually given to you by a trained doctor or nurse in a hospital or clinic.
Special care should be taken when administering this vaccine to young children. Your doctor will provide the necessary instructions.
Important note: This medicine has been prescribed for you only. Never share this medicine with anyone else.
What to do if the medication dose is increased?
Since this is given in a hospital setting, the chance of overdose is very low. However, if you feel that you have received too much of this medicine or if you experience any unusual symptoms, do not panic and inform the medical staff immediately. Alternatively, call the National Poisons Information Centre at the Colombo National Hospital . In case of an emergency, go to the Emergency Treatment Unit (ETU) of the nearest hospital.
What if I miss the day to get the vaccine?
It is very important to get this vaccine on schedule to maintain your B12 levels. If you are unable to attend the clinic or hospital on the scheduled day, please call your doctor or the relevant department in advance and ask for advice on the next day to come.
Things to be careful about when taking medicine
- Medical tests: During the time you are given this vaccine, your doctor will ask you to do things like blood tests to see how well the treatment is working. So don't forget to go to the clinic on the scheduled dates.
