For the most part, elevated levels of vitamin B12 are not dangerous. However, there are a few diseases that may cause these levels to increase. These include hypereosinophilic syndrome, polycythemia Vera, and two forms of leukemia.

High blood levels of vitamin B12 could be from cancer, liver disease, or kidney disease. Low levels of vitamin B12 could also be cause for concern.

Can B12 injections affect menstrual cycle?

Yes, a high dose of B12 can affect it. I had irregular menstruation symptoms, sometimes half a year and longer without menstruating, and -always- after a high dose of B12 (oral, not injected) the menstruation started a few hours later. This is probably caused by something called intrinsic factor - stomach cells that produce intrinsic factor are destroyed or missing, without them you can't absorb B12, no matter if your diet includes more or less B12. Only very high doses may get through (or injected B12), these high doses are not present in ANY food. As soon as your B12 storage is emptied (B12 can be stored in the body for 5-12 years or so), symptoms of B12 deficiency occur, it leads to pernicious anaemia, means that the production of red blood cells is defect, blood cells won't divide any more, you start to have less, but huge red blood cells, since they are not divided. In this environment your menstruation probably stops due to the deficiency of healthy red blood cells. My conclusion is that a very high dose of B12 probably leads to a sudden rush of blood cells, and this may start the menstruation, even after it has stopped for a very long time. Don't forget to supplement iron, and folic acid together with B12 - since the production of blood cells depends on them. For that reason a high dose of B12 may lead to an iron and folic acid deficiency, if not supplemented, they are all used up to build the new blood cells.

What does an elevated serum B-12 level indicate?

Elevated serum B12 is rare, and usually indicates a serious, potentially life-threatening disorder. Levels of B12 in the blood may be increased in myeloproliferative disorders, such as chronic myelogenous leukemia (cancer of the blood) or polycythemia vera (a disease characterized by an increased number and abnormal shape of red blood cells). Elevated B12 can also occur in liver disease such as hepatitis, when liver cells are broken down and release B12 into the blood.
