Treatment of hypertension (high blood pressure) in patients who require combination therapy to achieve adequate blood pressure control.
Candesartan blocks angiotensin II receptors, causing blood vessels to relax and widen, while hydrochlorothiazide removes excess fluid through increased urination, reducing overall blood volume and pressure.
May cause dizziness or dehydration; avoid potassium supplements unless directed. Not recommended during pregnancy. Common side effects include dizziness, upper respiratory infections, and changes in blood chemistry (electrolytes).
