How To Prevent And Treat Mercury Poisoning

Chelation Therapy

Chelation is used to treat metal poisoning from mercury, arsenic, and lead. Before having this treatment, doctors will perform blood and urine tests to confirm a patient has heavy metal poisoning. The treatment is typically given intravenously, though it is also available in an oral form. Patients receiving chelation therapy usually take a medication called ethylenediaminetetraacetic acid. Sometimes a drug known as dimercaptosuccinic acid is used for oral chelation. Both of these chelation drugs bind with the heavy metals in the bloodstream and form a compound the body excretes through urine. The chelation treatment may cause side effects such as a burning sensation at the intravenous site. Some patients may also experience fever, headache, vomiting, or nausea. In rare cases, patients may develop potentially serious side effects, including low calcium levels in the blood, kidney damage, heart failure, and sudden episodes of low blood pressure. Patients who have any concerns should discuss these with their doctor before beginning this therapy, and they will be monitored during intravenous treatment for any side effects. Patients on oral chelation therapy should inform their medical team of any side effects or other worrying changes that develop with their health.
