Summary
Thiazides reduce urinary calcium excretion, so calcium gluconate can raise serum calcium more than expected. Risk is greatest with repeated dosing or reduced renal function.
What this interaction means in plain words
Calcium gluconate and Captopril-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.
Calcium gluconate belongs to Gastrointestinal Tract; Captopril-hydrochlorothiazide belongs to Cardiovascular.
Why it happens
Thiazides enhance distal tubular calcium reabsorption, reducing renal calcium clearance.
What to do
Monitor serum calcium during repeated or prolonged calcium therapy and reduce the dose if hypercalcemia develops.
