Ostocal JR® tablet: Adults : 2 tablets daily; children : 1-2 tablets daily. Tablet must be chewed.
It increases the risk of hypercalcaemia with thiazides, it also reduces the absorption of tetracyclines and bisphosphonates.
In mild hypercalciuria [exceeding 300 mg (7.5 mmol)/24 hours] or renal failure, or where there is evidence of stone formation in the urinary tract, adequate checks must be kept on urinary calcium excretion; if necessary the dosage should be reduced or calcium therapy discontinued. High vitamin D intake should be avoided during calcium therapy, unless especially indicated. Thiazide diuretics reduce urinary calcium excretion so the risk of hypercalcaemia should be considered. Oral calcium administration may reduce the absorption of oral tetracycline or fluoride preparations. An interval of 3 hours should be observed if the two are to be given.
Keep away from light & moisture. Keep out of reach of children.
