Vitamin B12 Injection Safety

Are Vitamin B12 Injections Safe for You?

Vitamin B12 Injection SafetyYou might be wondering if supplementing B12 is safe. Supplementing B12 seldom has adverse side effects, and serious side effects are extremely rare.

The fact is that if you are not taking a prescription medication or herbal supplement that might interfere with B12 or one of the B complex mixes, then it is very rare for any harmful side effects to occur.

However, it is always advisable to consult your doctor regarding your health history and physical condition prior to supplementing with any vitamin or herb. Always use caution and follow your healthcare professional’s instructions.

Vitamin B12 is considered safe and no upper tolerable intake level has been established. In nonprofessionals' terms that means that vitamin B12 is not toxic or harmful in large doses.  

If you are not deficient in vitamin B12 or do not address the reasons for your deficiency, injections might not do much for your quality of life. Managing your B12 deficiency should be a multi-pronged approach. One needs to correctly diagnose their cobalamin deficiency, treat and reverse the deficiency and causes, and then prevent relapse.

The medical industry states the following about vitamin B12 supplementation safety:

In rare instances, mild side effects from cyanocobalamin can be diarrhea and swelling. Swelling appears to be most common in females over sixty that have been supplementing for 2-5 years. Less than 1%, 0.78% of the test group reported swelling. A majority of these people have other afflictions that might contribute to swelling. Studies are ongoing.

Serious side effects include muscle weakness, extreme thirst, confusion, shortness of breath, headache, exhaustion, reddening of the skin and a fast or irregular heartbeat. Severe side effects such as chest pains or difficulty breathing are rare.

After receiving a vitamin B12 injection, a low percentage of persons experience allergic symptoms such as itching, swelling, severe dizziness, rash, or difficulty breathing. Contact your doctor immediately if you experience these symptoms. Slight redness or swelling at the injection site of a B complex shot can sometimes occur.

Should any side effects arise, communication is the best way to combat side effects. This is accomplished best by informing your doctor of all medications and drugs, including alcohol that you may have taken prior to receiving a vitamin B12 injection.


Pregnancy and Breastfeeding

Insufficient data about the safety of excessive amounts of vitamin B12 during pregnancy is available.

Vitamin B12 is crucial for pregnant women of childbearing age and for older people. Fetus require adequate amounts of B12 so that their development proceeds without interruption. Vitamin B12 is crucial for cell replication, which is the process in which our DNA creates new cells that are vital for a growing fetus to develop fully.

Vitamin B12 deficiency during pregnancy has been associated with lower birth weight, preterm births and decreased mental function in infants.

Vegans and vegetarians that are breastfeeding should have their B12 levels checked to insure that their breastfed babies are receiving the amounts of vitamin B12 necessary to continue developing and remaining healthy.
