Overview & Description
Chelation therapy is used to remove poisons, also called toxins, from thebody. The most common use is for poisoning with a heavy metal, such as lead.Chelation uses a substance called a chelator to bind to the toxins. Once a toxin isbound to the chelator, it can then be passed out of the body. Most often, the toxin ispassed into the urine.
Who is a candidate for the procedure?

Other tests may also be used in certain settings.
Research is being done to see how well this therapy works for otherconditions. One disease experts are trying chelation with isatherosclerosis.However, the American Medical Association states that chelation has only beenproven useful for heavy metal poisoning.
How is the procedure performed?
There are several chelators in use, including the following:
Any of these can be given through an intravenous line,called an IV, or as a pill. An IV is a thin tube inserted through the skin and into a vein, usually inthe arm or hand.
If an IV infusion is needed, the procedure usually takes place in a clinic orin the doctor’s office. Sometimes, a person may need to be in the hospital,such as in cases of severe lead poisoning.A person can usually choose to sit or lie down. Next, an IV is started in a vein in thearm or hand. The chelator is mixed with fluids and slowly infused into the body. While theIV is running, a person can relax, sleep, or do other quiet activities. Most sessions lasta few hours, though some may be shorter or longer. The session is usually painless.Those who choose a pill form can take the pill at home just like any other medicine.
The total number of treatments given depends on the person’s health andneeds. For instance, those with a one-time poisoning may only need a few treatments.Those with Wilson diseaseoften need treatment for life.
