Question: Why is disodium EDTA (as opposed to calcium disodium EDTA) not recommended for lead chelation?
Answer: According to the cited reference “The safety and effectiveness of Na2EDTA in pediatric patients has not been established, and its use is not recommended because it induces hypocalcemia and possibly fatal tetany.” (Deaths Associated with Hypocalcemia from Chelation Therapy --- Texas, Pennsylvania, and Oregon, 2003—2005. MMWR, March 3, 2005, 55(08): 204-207)
