Blood Pressure Home > Enalapril


A blood pressure reading consists of two numbers -- for example, 120/80. The top number refers to the systolic blood pressure, and the bottom number expresses the diastolic blood pressure. During clinical studies in people taking enalapril, systolic blood pressure and diastolic blood pressure both decreased significantly. Certain factors, such as ethnicity and dose, affected how much the blood pressure dropped.
For people with congestive heart failure (CHF), the effects of enalapril on the heart and blood vessels can cause a decrease in the symptoms of congestive heart failure, including shortness of breath, fatigue, and swelling. Taking enalapril may also result in improved exercise tolerance.
For people with left ventricular dysfunction but no CHF symptoms, this drug can decrease the chances for developing heart failure symptoms along with a decrease in hospitalizations.

When and How Do I Take Enalapril?

Some general considerations for when and how to take the medication include the following:
  • It comes in tablet form. You generally take it once or twice a day, depending on your healthcare provider's instructions.
  • You can take it with or without food.
  • You should take it at the same time each day to maintain an even level of the medication in your blood.
  • In order for enalapril to work properly, you have to take it as prescribed. It will not work if you stop taking it.


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