Summary
Thiazides reduce urinary calcium excretion, so added calcium can lead to hypercalcemia, especially with repeated or high doses or reduced kidney function.
What this interaction means in plain words
Calcium chloride and Hydrochlorothiazide-losartan can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Thiazide-induced increase in renal tubular calcium reabsorption adds to calcium intake.
What to do
Monitor serum calcium when calcium is given repeatedly. Reduce the calcium dose if hypercalcemia occurs.
