Generally, the results of vitamin B12 injections can last about one week, but it is vital to have this administered by a healthcare provider. Also, the healthcare provider will determine the appropriate B12 dosage, depending on the current medical condition and diet.
In general, around 50 to 98 percent of the vitamin B12 consumed is eliminated from the body 48 hours after the shot is given.
If your vitamin B12 deficiency is not caused by a lack of vitamin B12 in your diet, you'll usually need to have an injection of hydroxocobalamin every 2 to 3 months for the rest of your life.
Getting large amounts of vitamin B-12 through vitamin B-12 shots is not likely to harm your health.
It may take a few weeks before your vitamin B12 levels and symptoms (such as extreme tiredness or lack of energy) start to improve. If you have hydroxocobalamin injections to boost your vitamin B12 levels at the start of treatment, the cyanocobalamin tablets may start to work within a few days.
So does vitamin B12 give you energy? While B12 doesn't directly provide energy, it does give the body the tools it needs to convert food molecules into energy. Getting the recommended daily amount of B12 can therefore help ensure that the body is able to make the energy it needs to do everything you need it to do.
Avoid alcohol for 48 hours after your treatment. Avoid strenuous exercise for 48 hours after your treatment. Avoid touching the injection site for 6 hours after your treatment. You may experience a dull ache at the injections site for around 1 hour after your treatment.
Vitamin B12 is considered an important brain and nervous system micronutrient and is often used for anxiety. It helps to ensure normal function for your nerves, which can help combat physical symptoms of anxiety.

B12 injections work quickly. They are one of the most effective ways for your body to assimilate vitamin B12. Within 48 to 72 hrs, your body will begin making new red blood cells. For deficiencies, you may require a number of injections over a few weeks to see peak impact.

If you are deficient in B12, a shot can help keep your energy levels functioning where they should be: "Vitamin B12 is an essential micronutrient that we all need in our diets," says Avena. "B12 shots can help you to feel more energetic, fight lethargy, and can also help with mood."
B12 injections are a quick way to boost immune system functioning and can help ward against diseases and illnesses. They can even help improve bone density, a factor in osteoporosis.

Safety and side effects
High doses of vitamin B-12, such as those used to treat a deficiency, might cause: Headache. Nausea and vomiting. Diarrhea.
Orally-swallowed B12 tablets are just as effective as injections in the vast majority of patients, except those with digestive issues that may hamper absorption. However, the rate at which the B12 is released can be a little slower meaning that if you need B12 quickly, injections will be the better option.
Deficiency of Vitamin B12 can result in hematological changes, neurological and psychiatric problems, which can manifest as irritability, changes in personality, depression, and memory loss [9]. It is also known to worsen depression by excitotoxic reactions caused by the accumulation of homocysteine [10].
Vitamin B12 helps increase the body's production of melatonin, making it important for regulating sleep-wake cycles. Higher B12 levels have been associated with a lower risk of depression.
