Zestril is used for:
Treating high blood pressure alone or with other medicines. It is used along with other medicines to manage heart failure or improve survival after a heart attack. It may also be used for other conditions as determined by your doctor.
Zestril is an angiotensin-converting enzyme (ACE) inhibitor. It works by relaxing blood vessels. This lowers blood pressure and helps the heart to pump blood more easily.
Do NOT use Zestril if:
you are allergic to any ingredient in this medicine
you have a history of angioedema (swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or hoarseness), including angioedema caused by treatment with an ACE inhibitor
you are in your second or third trimester of pregnancy
the patient is a CHILD with severe kidney problems
Contact your doctor or health care provider right away if any of these apply to you.
