Vitamin B12 Side Effects

 

Vitamin B12 is unusually a big molecule, scarce and involves a rather difficult absorption mechanism. Its scarcity is attributed to the fact that it cannot be synthesized by plants nor animals but only by a handful of algae and bacteria. Vitamin B12 side effects are unlikely to happen by diet alone because there are, in fact, very few excellent or good food sources. Ingestion of large doses can possibly happen if supplements are used. It is still safe to ingest as much as 1000 mcg provided there is no complicating sensitivity. or allergy

 

 
It is common to see adverse reactions or vitamin B12 side effects if it gets into the system of a person with allergy to it. This is generally associated to injectable preparations. On thing worth noting though at this point is that, it is still uncertain if the allergy is caused by the vitamin B12 itself or by the preservatives in the solution. Sensitivity to cobalt or cobalamin are also possibilities. During such instances, signs and symptoms include rashes, hives, diarrhea, chest pains, panic attacks, anxiety, and heart palpitations among others.

 
Vitamin B12 side effects can also be observed when it interacts with certain drugs or when the individual taking it is predisposed to certain conditions. What makes the absorption complicated are narrated below:

 
1.Leber’s Disease, a hereditary eye disease, can lead to blindness as a repercussion if the condition is not managed. Vitamin B12 can harm the optic nerves if predisposed.

 

 

2.Vitamin B12 deficiency may precipitate megaloblastic anemia or a type of anemia where the red blood cells are abnormally large. Such signs and symptoms are generally easy to treat but may also be difficult at times. If there is something to watch out for, it is the sudden appearance of vitamin B12 side effects especially after administration of B12 injections. If a therapy needs to be administrered, it is highly recommended that professional help be sought first.

 

3.Exposures to high levels of vitamin B12 may precipitate a disease called polycythemia vera. This is manifested by having a high number of red blood cells.

 

Adverse reactions can happen during drug interactions with the use of Metformin for diabetes, chloramphenicol for bacterial infections; and lansoprazole, omeprazole and cimetidine for peptic ulcer and gastroesophageal reflux.
The adverse interactions between vitamin B12 and these drugs lead to poor absorption of the vitamin. Vitamin B12 side effects and adverse reactions can easily be prevented if one would take an effort to consult a medical practitioner before drug interactions even happen..
