Calcium carbonate tablets should be administered during the meal. The dose is determined and individually adjusted according to the calcium and phosphate levels in the serum. The phosphate level in the serum should be from 0,8-1,5 mmol/l, while of calcium from 2,1-2,7 mmol/l.

If during the treatment, hypercalcemia appears, the dosage should be decreased. At patients with heavy hyperphosphataemia (serum phosphates from 7-15 mg %), prior to the initiation of the therapy with calcium carbonate, it is recommended a short administration of aluminum binders of phosphates and reduction of total intake of phosphates in the nutrition. When the phosphate level in the serum will be decreased from 5-7 mg % the therapy with calcium carbonate may begin.
