Taking EDTA can cause kidney failure, blood clotting, anemia, low blood pressure, irregular heartbeat, abnormal calcium, and low levels of potassium and magnesium in the blood, notes WebMD. It can also cause numbness, diarrhea, breathlessness, severe blistering and red skin, according to Drugs.com.
EDTA is a molecule that acts as a chelating agent, in that it can attach to metal molecules such as mercury and lead. For this reason, doctors sometimes use it in removing metals such as calcium from a patients blood and in the treatment of cancer. Some people use this product in lowering plaque and cholesterol levels in the body and in treating arteriosclerosis, Alzheimers disease and peripheral vascular disease. However, there is no medical evidence of EDTA's effectiveness in these health conditions, reports WebMD.
Doctors administer EDTA into the muscles or veins by injection. Before the administration, the patient has to tell the doctor about his medical history relating to conditions such as asthma, tuberculosis, seizure disorders and cardiovascular disease. This information is essential for pregnant and lactating mothers, as EDTA is harmful to babies, and it is not clear whether it can pass through breast milk. This allows the doctor to determine the safety of the patient taking this product and minimize possible side effects, advises Drugs.com.
