Your body requires B12 vitamins in order for the cells to work properly in your body. Vitamin B12 also helps in the formation of red blood cells. When you are deficient in vitamin B12 it can lead to anemia. Vitamin B12 helps to improve your metabolism rate, and helps to maintain the central nervous system. The natural sources of B12 are generally found in animal products such as meat, fish, milk, etc. To make up for the loss of this vitamin in your body your physician may require that you have B12 vitamin injections. They are given by your physician and can be very painful along with having several side effects.

Although there can be negative symptoms from the B12 vitamin injection it is useful for the body and the injections are non-toxic. Even if you are required to take them in a large amount most people do not face any problems, including little to no side effects. The side effects that are associated with these injections range from minor to severe. If you have any heart problems or history of blood clotting inform your physician before receiving the injection. With a history of blood clotting even one single side effect sometimes can be fatal.

These can include:

  • Diarrhea that is usually mild
  • Skin problems-itching, bumps on skin turning red, skin rash that usually happens at the injection site.
  • May also experience chest pain that can be accompanied by breathing problems
  • If you have undergone heart surgery recently and then take the vitamin injection there is a chance that your arteries may start to narrow down again.
  • You may have difficulty sleeping at night such as suffering from insomnia
  • Taking the
vitamin injections for weight loss could lead to side effects such as an upset stomach or nausea.

  • You may feel as if your entire body has swelled up after the injection
  • You may experience rapid heart rate, which is a dangerous side effect and requires immediate medical attention is required.
  • Excessive wheezing and coughing
  • You may experience muscle spasms and muscle cramping.
  • Panic attacks and anxiety

According to studies it is not the vitamin B12 that is responsible for any of these side effects but instead is the preservatives that are present in the injection formula. If there are any side effects they can vary from one patient to another. The one who is giving the vitamin injection should also know how to give it because the side affects that effect your skin depends on it.
