How Effective Is It?

A blood pressure reading consists of two numbers -- for example, 120/80. The top number is known as the systolic blood pressure, and the bottom number is the diastolic blood pressure. During clinical studies in people taking lisinopril, both systolic and diastolic blood pressures were significantly lowered. The higher the dose, the greater the drop in blood pressure tended to be. By lowering blood pressure, lisinopril can decrease the risks that often accompany long-term high blood pressure (see Effects of High Blood Pressure).
For people with congestive heart failure, the effects of lisinopril on the heart and blood vessels cause a decrease in the symptoms of congestive heart failure (including shortness of breath, fatigue, and swelling), as well as improved exercise tolerance.

When and How Do I Take It?

General considerations for when and how to take lisinopril include the following:
  • It comes in tablet form and is taken once a day.
  • You can take it with or without food.
  • It should be taken at the same time each day to maintain an even level of the medicine in your blood.
  • If you have difficulty taking the tablet, talk to your pharmacist or healthcare provider about a different form of lisinopril.
  • For it to work properly, you have to take it as prescribed. Lisinopril will not work if you stop taking it.

Dosing Information for Lisinopril

The dosage that your healthcare provider recommends will vary, depending on a number of factors, including:
  • Your age
  • The medical condition being treated
  • Other medical conditions you may have
  • Other medications you are currently taking.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
