Nowadays, people often ignore problems like fatigue, weakness, tingling or numbness in hands and feet. But in some cases these symptoms may be associated with vitamin B12 deficiency in the body. Vitamin B12 is essential for making red blood cells in the body, producing DNA and for the normal functioning of the nervous system. Its deficiency can lead to anemia along with fatigue and weakness, while prolonged deficiency can also lead to neurological symptoms.
Once B12 deficiency is confirmed, doctors often recommend tablets or injections as needed. But here one question is quite common—for how long should Vitamin B12 medicine be taken and is it safe to take it for a long time?
Treatment duration may vary from person to person
There is no fixed rule for how long to take Vitamin B12 medicine. It depends on why there is a B12 deficiency in the body and how severe the deficiency is.
If the deficiency is only due to not getting enough B12 in the diet and eating habits are improved, the duration of supplementation may be limited as per the doctor's advice. On the other hand, if the body cannot absorb B12 properly, long-term supplementation may be required.
Therefore, it would not be correct to say that every person should take B12 only for three months or that every person should take it throughout his life. The duration of treatment is decided according to the cause.
Who may need B12 long term?
Some health conditions make it difficult for the body to absorb B12. For example, conditions such as autoimmune gastritis, total gastrectomy, or removal of part of the terminal ileum of the small intestine may require long-term, even lifelong, B12 replacement.
In some other situations, the doctor may decide whether oral supplements are sufficient or whether injections are needed.
The dosage of B12 is also not the same for everyone.
Vitamin B12 dosage is not decided based only on age or fatigue. Doctors usually take into account the B12 levels, the cause of the deficiency, the symptoms, and the patient's other health conditions.
If the deficiency is related to diet, oral B12 supplements may be prescribed in many cases. But if there is a problem with the absorption of B12 in the body, a higher dose or injection may be required. Some guidelines suggest considering a dose of at least 1 mg per day of oral B12 in such cases.
Especially if persistent tingling, numbness or other neurological symptoms are present in the hands and feet, then treatment should not be delayed and treatment should be taken under doctor's supervision instead of deciding the dosage on your own.
Can taking B12 for a long time cause harm?
Vitamin B12 is generally considered a vitamin with low toxicity. According to the NIH, no prescribed Tolerable Upper Intake Level or maximum safe intake limit has been set for B12, because the possibility of its harm is considered low.
But this does not mean that one should keep taking high-dose supplements for a long time unnecessarily. If a person needs B12 supplements for a long time, it is better to get the reason and need for treatment reviewed from time to time with a doctor.
Don't ignore the symptoms of B12 deficiency
Vitamin B12 deficiency may cause symptoms like fatigue, weakness, pale skin, palpitations, tingling or numbness in hands and feet. Neurological symptoms can occur even without anemia, so it is important to get checked if such symptoms persist.
Even after starting the treatment, it is not necessary that the symptoms disappear completely immediately. For some people, improvement may begin within a few weeks, while symptoms may take longer to resolve completely.
Do not start or stop B12 yourself
If B12 deficiency has been revealed in your report, then definitely understand from the doctor what is the reason for the deficiency and for how long the supplement has to be taken. Taking B12 pills for a long time only on the basis of fatigue or weakness is not the right approach.
Especially if you are feeling constant tingling, numbness, difficulty in walking or severe weakness in your hands and legs, then it is important to consult a doctor immediately.
Conclusion: The duration of vitamin B12 supplementation may vary from person to person. Treatment for dietary deficiency may be of limited duration, whereas long-term treatment may be required if there is a permanent problem with the absorption of B12 in the body. B12 is generally considered safe, but the correct dosage and duration should be determined based on your diagnosis and the cause of the deficiency.
