When working with Zestoretic, a prescription combo of lisinopril and hydrochlorothiazide used to treat high blood pressure and heart failure. Also known as Zestril‑Hydrochlorothiazide, it helps relax blood vessels and remove excess fluid, lowering the workload on the heart.
One of the key components, lisinopril, is an ACE inhibitor that blocks a hormone that narrows blood vessels. Paired with hydrochlorothiazide, a thiazide diuretic that promotes water loss through the kidneys, the combo tackles both pressure and fluid retention. These two drugs together address the underlying condition of hypertension, a major risk factor for heart failure, stroke, and kidney disease. Because Zestoretic requires a doctor’s prescription, proper dosing and monitoring are essential to avoid side effects like cough, dizziness, or electrolyte imbalance.
Most patients start with a low dose taken once daily, usually in the morning, and the doctor may adjust it based on blood pressure readings. Common side effects are mild—headache, mild dizziness, or increased urination—but serious reactions such as swelling or severe cough should prompt an immediate call to a healthcare provider. When buying Zestoretic online, verify that the pharmacy is licensed, asks for a valid prescription, and offers a clear return policy. Checking the pharmacy’s registration with the local health authority helps protect against counterfeit pills and ensures you receive the correct dosage.
