How often should you take B12 injections for pernicious anemia?
If you have pernicious anemia you may require lifelong treatment, though this is made simple by taking regular shots.
To begin treatment, doctors may suggest you inject B12 into the muscle (intramuscularly) every day. If you see an improvement in symptoms after injecting daily for one week, it is recommended that you limit injections to once every 2 days, for two weeks (7 doses in total).
Finally, after your B12 levels have returned to a stable state, shots will be reduced to one injection per month. If you begin to re-experience symptoms of pernicious anemia after reducing the frequency of your injections, you could try taking B12 injections more often again. Obviously, everybody’s situation is different, so you should always consult your doctor before you set out to begin a new treatment.
Vitamin B12 injection dosages for diseases and conditions
- Vitamin B12 Deficiency
Causing symptoms such as anxiety, nausea, headache and fatigue, B12 deficiency isn’t fun. To reduce symptoms and sustain normal vitamin B12 levels, dosages of 2000mg may be taken daily until symptoms are reduced. Blood levels can be checked to ensure there is sufficient B12 in the body. After this, it is important to maintain B12 levels by taking weekly injections of 1000mg for at least a month, before you are sure your body has returned to its fully functioning state. To avoid future deficiencies, you can take monthly shots or as frequently as needed.
- Gastrointestinal Disorders
B12 shots are the best option for patients with gastrointestinal issues, as injections bypass the stomach and the vitamin is easily absorbed. Gastrointestinal issues are a primary cause of B12 deficiency, so following the dosages and frequencies mentioned above will be useful in overcoming negative symptoms caused by gastrointestinal issues.

In gastrointestinal disorders such as Celiac and Crohn’s Disease is when part of the intestine that absorbs B12 through food and other natural resources is damaged.
Where severe deficiency is seen, daily injections are recommended until symptoms reside somewhat. After this, monthly B12 injections maintain the B12 levels in the body. Monthly injections may be required for life, depending on which other methods of treatment the patient may be using, such as surgery of the intestines.
- Autoimmune Disorders
Lupus patients require B12 injections as the disorder causes deficiencies. Frequent dosages should be maintained to avoid negative effects. Reports also suggest that regular dosages of B12 could reduce flare-ups in lupus patients who are not actively experiencing the negative symptoms of the disease.
Patients with conditions like osteoarthritis and rheumatoid arthritis could benefit from taking B12 on a regular basis. Research shows that symptoms improved greatly in those with osteoarthritis when they took B12 supplements daily for two months. This may be because a few studies have shown that B12 may play a role reducing discomfort and stiffness in arthritis sufferers.
