Treating high blood pressure.
Monopril HCT is an angiotensin-converting enzyme (ACE) inhibitor and thiazide diuretic combination. It works to lower your blood pressure by removing excess fluid from the body and causing blood vessels to relax or widen.

- you have a history of angioedema (swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or unusual hoarseness), including angioedema caused by treatment with an ACE inhibitor
- you are unable to urinate
- you are pregnant
- 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.
