Vitamin B12 is an important component in cell regeneration, blood production, brain and bone development. People with vitamin B12 deficiency (anemia) will have symptoms such as depression, exhaustion, poor memory, you should see a doctor for advice on vitamin B12 supplements. [1] X Research Source The doctor will draw blood to measure the blood concentration of vitamin B12 in the whole body, if the concentration is too low, you should inject additional. Vitamin B12 injections are injections containing a man-made B12 called cyanocobalamin. You should talk to your doctor about allergies or medical conditions that could cause an adverse reaction to vitamin B12.

Talk to your doctor about vitamin B12 injections. Explain the reasons for injecting vitamin B12 supplements. Your doctor will check your blood levels of B12 and a few other tests. If your doctor feels you are suitable for B12 injections, they will prescribe the appropriate dose. They teach you or your nurse how to inject correctly. You should not self-inject without proper training.
- You need to buy medicine at your local pharmacy. Do not exceed the dose of vitamin B12 prescribed by your doctor.
- When injecting vitamin B12, your doctor may order regular blood tests to check your body’s response to the injection. [4] X Research Sources

Discuss complications with vitamin B12 injections with your doctor. Talk to your doctor about allergies and medical conditions that may make you ineligible for a B12 shot. Because vitamin B12 injection contains cyanocobalamin, you should not use this medicine if you are allergic to cyanocobalamin or cobalt, or you have Leber’s optic nerve atrophy. You should not get the shot if you have the following symptoms: [5] X Research Source
- Allergy or cold symptoms affecting the nose, such as sinusitis or sneezing.
- Kidney or liver disease.
- Iron deficiency or fpic acid.
- Infection symptoms.
- Are taking medication or have treatment related to bone marrow.
- Are pregnant or plan to become pregnant while receiving vitamin B12 injections. Cyanocobalamin passed into breast milk could harm the baby.

Be aware of the benefits of vitamin B12 injections. If you have anemia or vitamin B12 deficiency, you need to treat it with B12 injections. Many people have difficulty absorbing B12 in food or by mouth, so they have to choose an injection. Vegetarians do not eat animal meat, so they can supplement vitamin B12 to ensure health.

Select the injection site. The ideal injection site depends on the age and comfort level of the person being injected. Health care professionals need to test injections to monitor drug reactions and check for side effects. Here are 4 common injection sites: [8] X Research Source
- Biceps: This is the injection site for adults, young people or middle-aged people. Older people can still inject at this site if the muscles in the biceps, deltoids are still well developed. However, if the dose is higher than 1ml, it cannot be injected through the upper arm.
- Thigh: This is the most common injection site for people who inject themselves, or give injections to infants and young children. Thighs are a good location because there is a lot of fat and muscle under the skin. You should inject into the muscle, the large thigh muscle between the groin and the knee, 15-20cm from the knee up. [9] X Research Source
- Hip: The injection site is located on the side of the hip, below the pelvis, suitable for both young people and adults. Experts often recommend injecting in this location so as not to affect blood vessels or nerves when injecting.
- Buttock: The upper, lateral aspect of the buttocks or Dorsogluteals on the side of the body are also common injection sites. Only a medical professional should administer the injection at this site because it is located near blood vessels and sciatic nerve, which can be affected if the injection is not done properly.

Select the injection method. The injection process seems simple, but there are still 2 ways to inject vitamin B12 as follows: [10] X Research source
- Intramuscular: This type of injection is more common because they usually give better results. The needle is inserted deep into the muscle tissue at a 90 degree angle. Once the needle is in the muscle, you need to pull the plunger back a little to make sure the needle doesn’t go into a blood vessel; If you don’t see the blood being sucked back, then slowly push the plunger to pump the medicine in. When vitamin B12 is pushed through the needle, it is immediately absorbed into the surrounding muscle. This ensures that the entire vitamin B12 will be absorbed into the body.
- Subcutaneous injection: This type of injection is less common. The needle is inserted under the skin at a 45-degree angle, as opposed to being inserted deep into the muscle area. The outer skin may be pulled away from the muscle tissue to make sure the injection doesn’t hit the muscle. The most suitable injection site for this method is the biceps injection.

Administer the injection. Use the thumb and forefinger of the other hand to secure the skin of the injection site. No matter what site of injection you choose on your body, you should hold the skin tight to make it easier to inject the medicine. [17] X Research Source
- Notify the person receiving the injection when you are about to inject the medication. Then you insert the needle under the skin at the correct angle. Hold the needle firmly and slowly push the plunger until all of the medicine is in the body.
- After inserting the needle, pull the plunger back slightly to check if you’re not hitting a blood vessel. If no blood is seen, proceed with the injection. [18] X Research Sources
- Try to inject into the relaxed muscle area. If the person receiving the injection is nervous or stressed, ask them to keep weight on the leg or arm you did not inject. This will help relax the muscle where the injection is being administered. [19] X Research Source
- If you are injecting vitamin B12 yourself, use your other hand to hold the skin of the injection site firmly. Relax the muscle and insert the needle at the correct angle. Check for blood in the needle, then inject the entire drug into the body.

Dispose of the needle properly. Do not throw used needles in the regular trash. You can ask your doctor or pharmacist to purchase a safe for sharps or design your own. [21] X Research Source
- Use coffee cans with lids. Cut the cap wide enough to fit the needle. Once the can is full, take it to your doctor’s office for proper disposal, or seek out a biohazard waste disposal service.
- You can use a thick detergent bottle to store used needles (don’t forget to label the bottle containing the needles and not the detergent).
