Summary
Thiazides reduce urinary calcium excretion, so calcium given with them can lead to hypercalcemia. Risk increases with high doses, repeated dosing or reduced kidney function.
What this interaction means in plain words
Calcium chloride 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.
What to do
Monitor serum calcium when calcium is given repeatedly or at high dose. Adjust calcium dosing or the diuretic if hypercalcemia occurs.
What to ask your pharmacist
