Quinapril + Hydrochlorothiazide (quinapril and hydrochlorothiazide) — Uses, Dosage, Side Effects & Safety

Drug class: Cardio-Metabolic

Overview

Quinapril + Hydrochlorothiazide is a prescription medication used to treat high blood pressure (hypertension). It combines two medicines: quinapril, an angiotensin-converting enzyme (ACE) inhibitor, and hydrochlorothiazide, a thiazide diuretic (water pill). Together, they help relax blood vessels and remove excess salt and water from the body, making it easier for your heart to pump and lowering your blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This combination is often prescribed when one medicine alone does not control blood pressure adequately. Most people take it once daily, with or without food. Key points: Take this medication exactly as prescribed, do not stop suddenly without consulting your doctor, and have your blood pressure and kidney function checked regularly.
