Lisinopril — Uses, Dosage, Side Effects & Safety

Drug class: Angiotensin-Converting Enzyme (ACE) Inhibitor

Overview

Lisinopril is a prescription medication used to treat high blood pressure (hypertension), heart failure, and to improve survival after a heart attack. It may also be prescribed for certain kidney conditions, especially in people with diabetes. Lisinopril works by relaxing blood vessels, making it easier for your heart to pump blood and lowering blood pressure. It belongs to a group of medicines called ACE inhibitors, which block a substance in the body that causes blood vessels to tighten. Key points: Lisinopril is usually taken once daily, with or without food. It is important to take it regularly, even if you feel well, as high blood pressure often has no symptoms. Do not stop taking lisinopril without talking to your doctor.
