Calciumade Overdosage

Calcium: No data available on overdosage when taken in the recommended dose. However, in particularly susceptible individuals (i.e., patients with kidney failure), doses greater than 2 g elemental calcium per day may cause high levels of calcium in the urine and lead to kidney stones, which may result to kidney damage.
Vitamin D: Chronic ingestion of 50,000 - 100,000 IU (1.25 - 2.5 mg) of vitamin D daily may result in hypervitaminosis D. Signs and symptoms include hypercalcemia, hypercalciuria, anorexia (loss of appetite), nausea, vomiting, polyuria (frequent urination), polydipsia (excessive thirst), weakness and lethargy (fatigue).
Zinc: Rare occurrences of acute zinc poisoning have been reported. The toxicity signs observed after ingestion of high zinc doses (4 - 8 grams) include nausea, vomiting, diarrhea, fever, metallic taste, and lethargy.
If the patient has taken more than the recommended dosage, consult a doctor or contact a Poison Control Center right away.
