Summary

Thiazide diuretics reduce urinary calcium excretion, so taking them with calcium supplements can raise serum calcium. Hypercalcemia is more likely with high doses, renal impairment, or concurrent vitamin D.

What this interaction means in plain words

Calcium citrate and Candesartan-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.

Evidence level: Moderate

Why it happens

Thiazides enhance distal tubular calcium reabsorption, decreasing urinary calcium loss.

What to do

Monitor serum calcium periodically and reduce the calcium or vitamin D dose if hypercalcemia appears.
