Symptoms: anorexia, lassitude, nausea and vomiting, diarrhea, polyuria, sweating, headache, thrist and vertigo.
Treatment: Both the drug and calcium supplements should be withdrawn, maintenance of a low-calcium diet, administration of oral or IV fluids and if needed, corticosteroids or other drugs, particularly calciuric diuretics (e.g. furosemide and ethacrynic acid) to decrease serum calcium concentrations. Hemodialysis or peritoneal dialysis against a calcium-free dialysate may also be used. If ingestion is recent, gastric lavage or emesis may prevent further absorption. If the drug has passed through the stomach, administration of mineral oil may promote fecal elimination.
