Dimercaptosuccinic acid (DMSA)

Dimercaptosuccinic acid (DMSA) is used as an oral chelator for removing toxins from the blood and kidneys. It is also used for heavy metal poisoning, specifically lead, arsenic, and mercury poisoning in birds. It binds with high specificity to ions of lead in the blood to form a water-soluble complex that is subsequently excreted by the kidneys.

Typical Dosage: 25-35 mg/kg PO q12h x 5 days per week, administered for 3-5 weeks.
