Zestoretic is a combination blood pressure medication for adults. It contains lisinopril (an angiotensin-converting enzyme (ACE) inhibitor) and hydrochlorothiazide (a thiazide diuretic). It comes as a tablet that's taken by mouth once per day. Your prescriber will determine your dosage based on how high your blood pressure is and if you're taking other blood pressure medications. Some of the more common side effects it can cause include dizziness, headache, and cough. Zestoretic (lisinopril / hydrochlorothiazide) is available as a generic.
High blood pressure in adults
Zestoretic is a combination of two medications that work together to lower blood pressure:
Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor. It relaxes your blood vessels by blocking a protein (ACE) that normally squeezes your blood vessels.
Hydrochlorothiazide is a thiazide diuretic, which is a water pill. It works in your kidneys to remove extra water and certain electrolytes (like sodium and potassium). This helps lower blood pressure.
