Dimercaptosuccinic acid (DMSA)

Dimercaptosuccinic acid (DMSA) is an orally administered chelating agent used for treatment of poultry with heavy metal poisoning. 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. Can be used for the treatment of lead, zinc, arsenic, cadmium and mercury toxicity.

Note: DMSA has a narrow margin of safety and should be used with caution.
  • 25-35 mg/kg PO q12 for 5 days/week for 3-5 weeks.
  • Use caution in birds with suspected liver disease as it may make the condition worse.
