Lisinopril is used in the treatment of hypertension (high blood pressure), the prevention of heart attack and stroke, and heart failure.
How Lisinopril works Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor. It works by reducing stress on the heart and relaxing blood vessels so that blood flows more smoothly and the heart can pump blood more efficiently.
Common side effects of Lisinopril include cough, dizziness, increased potassium levels in the blood, hypotension (low blood pressure), and headache.
