Overdosage for zinc
Single intravenous doses of 1 to 2 mg Zinc/kg body weight have been given to adult leukemic patients without toxic manifestations. However, acute toxicity was reported in an adult when 10 mg Zinc was infused over a period of one hour on each of four consecutive days. Profuse sweating, decreased level of consciousness, blurred vision, tachycardia (140/min), and marked hypothermia (94.2° F) on the fourth day were accompanied by a serum Zinc concentration of 207 mcg/dl. Symptoms abated within three hours.
Hyperamylasemia may be a sign of impending Zinc overdosage; patients receiving an inadvertent overdose (25 mg Zinc/liter of TPN solution, equivalent to 50 to 70 mg Zinc/day) developed hyperamylasemia (557 to 1850 Klein units; normal: 130 to 310).
Death resulted from an overdosage in which 1683 mg Zinc was delivered intravenously over the course of 60 hours to a 72 year old patient.
Symptoms of Zinc toxicity included hypotension (80/40 mm Hg), pulmonary edema, diarrhea, vomiting, jaundice, and oliguria, with a serum Zinc level of 4184 mcg/dl.
Calcium supplements may confer a protective effect against Zinc toxicity.
