Vitamin B12 Injections
Vitamin B12 plays an important role in keeping your blood and nervous system healthy. When your body does not get or absorb enough of this essential vitamin, a deficiency can develop and potentially affect your health and everyday wellbeing.
At The Village Pharmacy in Biddenham, our pharmacy team provides professional support for people with vitamin B12 deficiency. Where vitamin B12 replacement has been recommended, we can help you understand the service and the next steps appropriate to your individual circumstances.
Whether you have previously been advised that you require vitamin B12 replacement or would like more information about the support available, contact our team to discuss your needs.
What Is Vitamin B12?
Vitamin B12 is an essential nutrient that the body needs to function normally. Among its important roles, it contributes to the production of healthy red blood cells and helps maintain the nervous system.
Most people obtain vitamin B12 naturally through their diet. It is found in foods including meat, fish, eggs and dairy products, as well as some fortified foods. However, getting enough B12 from your diet does not necessarily mean that your body can absorb and use it effectively.
A deficiency can develop when you do not consume enough vitamin B12 or when your body has difficulty absorbing it. Identifying the underlying reason for a deficiency is important because it can influence the type and duration of treatment you require.
What Can Cause Vitamin B12 Deficiency?
There are several possible reasons why someone may develop low vitamin B12 levels. Dietary intake is one potential factor, particularly for people who consume few or no animal products without obtaining sufficient B12 from fortified foods or supplements.
However, deficiency is not always related to diet. Other potential causes or risk factors include:
- Problems absorbing vitamin B12 from the digestive system
- Autoimmune gastritis, which can affect the body’s ability to absorb B12
- Certain stomach or intestinal conditions or surgery
- Long-term use of some medicines that can affect B12 absorption
- A diet that does not provide sufficient vitamin B12
Because there are different possible causes, it is important not to assume that symptoms are caused by vitamin B12 deficiency without appropriate professional assessment.
What Are the Symptoms of Vitamin B12 Deficiency?
Vitamin B12 deficiency can cause a wide range of symptoms, and some people may experience a deficiency without developing obvious symptoms initially.
Possible signs and symptoms can include:
- Extreme tiredness or a lack of energy
- Problems with memory or concentration
- Pins and needles
- Muscle weakness
- Problems with balance or coordination
- A sore or red tongue
- Changes in vision
These symptoms can also be caused by many other conditions. If you think you may have a vitamin B12 deficiency but have not been diagnosed, seek appropriate medical advice rather than relying on symptoms alone. Blood tests may be used alongside your symptoms and medical history when investigating a possible deficiency.
You can find further information in the NICE guidance on vitamin B12 deficiency.
How Do Vitamin B12 Injections Work?
Vitamin B12 replacement is available in different forms. Depending on the cause and individual circumstances, treatment may involve oral B12 replacement or injections.
Where intramuscular vitamin B12 replacement is appropriate, treatment is given as an injection into a muscle. This allows vitamin B12 to be delivered directly into the body rather than relying on absorption through the digestive system.
How frequently injections are required depends on the reason for treatment and how an individual responds. Some people initially require injections more frequently before moving onto less frequent maintenance treatment. For others, treatment may be required over the longer term.
The NHS hydroxocobalamin guidance provides more information about injectable vitamin B12 and how it is used.
Why Might Injections Be Recommended Instead of Tablets?
Not everyone with vitamin B12 deficiency needs injections. Oral vitamin B12 replacement can be appropriate in some circumstances, particularly depending on the cause of the deficiency.
Intramuscular injections may be considered when problems with absorption mean that obtaining sufficient vitamin B12 through diet or standard supplementation is difficult. NICE also identifies circumstances in which injections may be considered instead of oral replacement based on an individual’s clinical needs.
The appropriate treatment therefore depends on more than simply having a low B12 level. A healthcare professional can consider the likely cause of the deficiency and other relevant factors when determining an appropriate approach.
What Happens When You Have a B12 Injection?
Vitamin B12 injections are administered into a muscle by an appropriately trained healthcare professional. The process itself is generally quick, making appointments relatively straightforward to fit into your routine.
As with any injection, you may experience some discomfort at the injection site. Hydroxocobalamin can cause mild pain, swelling or itching where the injection was given, and some people may experience other side effects.
Your healthcare professional can explain what to expect and provide appropriate advice before treatment. Make sure you provide accurate information about your health, medicines and any previous reactions before receiving an injection.
How Quickly Do B12 Injections Work?
Hydroxocobalamin starts working straight away to replace vitamin B12, but that does not mean symptoms necessarily disappear immediately. According to the NHS, it can take several days or weeks before some people begin to notice an improvement in symptoms.
Your individual response will depend on factors such as the cause and severity of your deficiency. This is why B12 injections should not be promoted as an instant energy boost or quick solution for general tiredness.
If tiredness or another symptom is not being caused by vitamin B12 deficiency, increasing B12 levels may not address the underlying problem. Persistent or unexplained symptoms should be appropriately investigated.
How Often Are Vitamin B12 Injections Needed?
There is no single injection schedule that is appropriate for everybody. The frequency and duration of treatment depend on factors including the cause of the deficiency, symptoms and response to treatment.
Some people may initially require several injections over a relatively short period. Depending on the cause and response to treatment, injections may be given less frequently following initial treatment. Where the underlying cause of a deficiency is irreversible, long-term or lifelong replacement may sometimes be necessary.
You should follow the treatment schedule recommended for your individual circumstances rather than changing the frequency of your injections without appropriate professional advice.
