Glucocorticoids, such as prednisone, reduce the absorption of oral calcium.
Calcium reduces absorption of tetracycline, not the reverse. These drugs should be administered at least 1 hour apart.
Thiazide diuretics reduce renal calcium excretion and may cause hypercalcemia. The drugs can be administered concurrently.
Calcium reduces absorption of thyroid hormone, not the reverse, therefore they should be taken several hours apart.

Most signs and symptoms of vitamin D toxicity occur secondary to hypercalcemia, which is demonstrated by the patient's serum calcium level. Clinical manifestations include nausea, vomiting, constipation, weakness, fatigue, polyuria, and nocturia. A high fluid intake is recommended as part of the treatment.
Vitamin D supplements would be discontinued immediately, because the patient is showing signs of toxicity.
Foods such as milk, cheese, and yogurt are high in calcium and should be eliminated. In addition, milk typically is fortified with vitamin D.
Calcium supplements would further increase calcium levels and vitamin D toxicity.
