Thiazides reduce urinary calcium excretion, so calcium salts given with them can lead to hypercalcemia. Patients with renal impairment or on high calcium doses are most at risk.
What this interaction means in plain words
Calcium acetate and Fosinopril-hydrochlorothiazide 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
Thiazides enhance distal tubular calcium reabsorption, raising serum calcium.
