Vasotec is used for:
Treating high blood pressure, heart failure, and other heart problems. It may be used alone or with other medicines. It may also be used for other conditions as determined by your doctor.

Vasotec is an angiotensin-converting enzyme (ACE) inhibitor. It works by helping to relax blood vessels. This helps to lower blood pressure.

Do NOT use Vasotec if:
you are allergic to any ingredient in Vasotec or similar medicines (eg, captopril, lisinopril)
you are pregnant
you are taking dextran sulfate or potassium-sparing diuretics (eg, amiloride)

Contact your doctor or health care provider right away if any of these apply to you.

Some MEDICINES MAY INTERACT with Vasotec . Tell your health care provider if you are taking any other medicines, especially any of the following:
Diuretics (eg, furosemide, hydrochlorothiazide) because excessive decreases in blood pressure may occur, which may cause dizziness, especially upon standing, or fainting

Nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, aspirin, indomethacin) because the effectiveness of Vasotec may be decreased and the risk of kidney damage may be increased
Lithium or thiopurines (eg, azathioprine) because the risk of serious side effects may be increased by Vasotec
Oral diabetes medicine (eg, glyburide) because side effects, including a low blood sugar level (eg, hunger, shakiness or weakness, dizziness, headache, sweating), may be increased by Vasotec
Potassium supplements or potassium-sparing diuretics (eg, amiloride) may cause high blood potassium levels (eg, listlessness, confusion, abnormal skin sensations of the arms and legs, heaviness of the limbs, slow or irregular heartbeat, or stopping of the heart) when used with Vasotec
