1. What Zestril is and what it is used for
Zestril contains a medicine called lisinopril. This belongs to a group of medicines called ACE inhibitors.
Zestril can be used for the following conditions: To treat high blood pressure (hypertension). To treat heart failure. If you have recently had a heart attack (myocardial infarction). To treat kidney problems caused by Type II diabetes in people with high blood pressure.
Zestril works by making your blood vessels widen. This helps to lower your blood pressure. It also makes it easier for your heart to pump blood to all parts of your body.
2. What you need to know before you take Zestril

The allergic reaction may have caused swelling of the hands, feet, ankles, face, lips, tongue or throat. It may also have made it difficult to swallow or breathe (angioedema). If you have taken or are currently taking sacubitril/valsartan, a medicine used to treat a type of long-term (chronic) heart failure in adults, as the risk of angioedema (rapid swelling under the skin in an area such as the throat) is increased.
if a member of your family has had severe allergic reactions (angioedema) to an ACE inhibitor or you have had severe allergic reactions (angioedema) without a known cause. if you are more than 3 months pregnant.
