Vasotec is prescribed alone or in combination with other drugs to treat high blood pressure or congestive heart failure. After a heart attack, Vasotec has been found to be effective in improving function of the damaged heart and in reducing symptoms and hospitalizations related to heart failure.

Vasotec is a high blood pressure medication known as an ACE inhibitor. It works by preventing a chemical in your blood called angiotensin I from converting into a more potent form that increases salt and water retention in your body. It is effective when prescribed alone or in combination with other medications, especially thiazide-type diuretics. It is also prescribed in the treatment of congestive heart failure, usually in combination with diuretics and digitalis, and is prescribed as a preventive measure in certain conditions that could lead to heart failure.


The usual oral dose for treating high blood pressure is 2.5-40 milligrams once daily. It may also be administered twice daily. The dose for treating heart failure is 2.5-20 milligrams given twice daily. The usual intravenous dose is 1.25 milligrams every 6 hours.


High Blood Pressure

The usual starting dose for people not using diuretics is 5 mg, taken once a day. The usual dose is 10 to 40 mg per day, taken as a single dose or divided into 2 smaller doses.

If you are taking a diuretic, your physician may ask you to stop for 2 to 3 days before using Vasotec. Otherwise, he or she may give an initial dose of 2.5 mg of Vasotec under medical supervision before any further medication is indicated.

If you have a kidney disorder, your dosage will be adjusted according to its severity.

To Treat Heart Failure

This medication can be prescribed in conjunction with digitalis and diuretics in people with heart disease. The usual starting dose is 2.5 mg twice a day.

The usual regular dose is 2.5 to 20 mg each day, taken in 2 separate doses. The maximum daily dose is 40 mg, in 2 separate doses.

To Prevent Heart Failure

The usual starting dose is 2.5 mg twice a day, to be gradually increased to 20 mg a day divided into smaller doses.


Vasotec can be prescribed for high blood pressure in children 1 month to 16 years old. Dosage is determined by weight. The usual starting dose is 0.08 mg per 2.2 pounds of body weight (up to 5 mg) once a day. Doses above 40 mg have not been tested in children.
