Enalapril and Hydrochlorothiazide Overview
Enalapril and hydrochlorothiazide is a prescription medication used to treat high blood pressure. It is a single product containing 2 medications: enalapril and hydrochlorothiazide. Enalapril belongs to a group of drugs called angiotensin-converting enzyme (ACE) inhibitors. Enalapril 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. It is given once or twice daily, with or without food.
Common side effects of enalapril and hydrochlorothiazide include dizziness, tiredness (fatigue), and headache. Do not drive or operate heavy machinery until you know how this medication affects you.
