Fosinopril and Hydrochlorothiazide Overview
Fosinopril and hydrochlorothiazide 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 fosinopril and hydrochlorothiazide include headache, cough, and upper respiratory infections.
Fosinopril and hydrochlorothiazide can also cause tiredness (fatigue) and dizziness. Do not drive or operate heavy machinery until you know how fosinopril and hydrochlorothiazide affects you.
