Calcium Disodium Versenate
(edetate calcium disodium) Injection,USP


Calcium Disodium Versenate (edetate calcium disodium injection) is capable of producing toxic effects which can be fatal. Lead encephalopathy is relatively rare in adults, but occurs more often in pediatric patients in whom it may be incipient and thus overlooked. The mortality rate in pediatric patients has been high. Patients with lead encephalopathy and cerebral edema may experience a lethal increase in intracranial pressure following intravenous infusion; the intramuscular route is preferred for these patients. In cases where the intravenous route is necessary, avoid rapid infusion. The dosage schedule should be followed and at no time should the recommended daily dose be exceeded.

Each 5 ml ampul contains 1000 mg of edetate calcium disodium (equivalent to 200 mg/ml) in water for injection.
