What is lisinopril used to treat?

High blood pressure. Lisinopril is a medication that is mainly used to treat high blood pressure (HBP) in adults and children, in whom it’s FDA-approved over 6 years of age (although it may sometimes be prescribed “off-label” to children who are younger). It is also prescribed to people who have heart failure or who have had a heart attack, even if they do not have HBP, to prevent future events.
