Monopril HCT treats high blood pressure. This medication has two components, fosinopril and hydrochlorothiazide. Do not take Monopril HCT during pregnancy.
Monopril HCT Overview
Monopril HCT is a prescription medication used to treat high blood pressure. It is a single product containing 2 medications: fosinopril and hydrochlorothiazide. Fosinopril belongs to a group of drugs called angiotensin-converting enzyme (ACE) inhibitors. Fosinopril works by blocking the ACE enzyme, which helps blood vessels to relax and lowers blood pressure. Hydrochlorothiazide belongs to a group of drugs called thiazide diuretics, which work by stopping reabsorption of salt into your body. This prevents fluid from building up in the body.
This medication comes in tablet form and is typically given once daily with or without food.
Common side effects of Monopril HCT include headache, cough, and upper respiratory infections.
Monopril HCT can also cause tiredness (fatigue) and dizziness. Do not drive or operate heavy machinery until you know how Monopril HCT affects you.
This brand is no longer available, but the generic, fosinopril and hydrochlorothiazide, is available.
