Benazepril is used for:
Treating high blood pressure. It may be used alone or with other blood pressure medicines. It may also be used for other conditions as determined by your doctor.
Benazepril is an angiotensin-converting enzyme (ACE) inhibitor. It works by relaxing the blood vessels, which helps to lower blood pressure.
Do NOT use benazepril if:
- you are allergic to any ingredient in benazepril or to any other ACE inhibitor (eg, lisinopril)
- you have a history of angioedema (eg, swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or hoarseness)
- you are pregnant
- the patient is a child with severe kidney problems
- you are taking a medicine that contains aliskiren and you also have diabetes or kidney problems. Check with your doctor or pharmacist if you are not sure if a medicine you take contains aliskiren
Contact your doctor or health care provider right away if any of these apply to you.
