WHY is this medicine prescribed?
The combination of enalapril and hydrochlorothiazide is used to treat high blood pressure. Enalapril is in a class of medications called angiotensin-converting enzyme (ACE) inhibitors. It works by decreasing certain chemicals that tighten the blood vessels, so blood flows more smoothly. Hydrochlorothiazide is in a class of medications called diuretics ('water pills'). It works by causing the kidneys to get rid of unneeded water and salt from the body into the urine.
HOW should this medicine be used?
The combination of enalapril and hydrochlorothiazide comes as a tablet to take by mouth. It is usually taken with or without food once or twice a day. To help you remember to take enalapril and hydrochlorothiazide, take it around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take enalapril and hydrochlorothiazide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Enalapril and hydrochlorothiazide controls high blood pressure but does not cure it. Continue to take enalapril and hydrochlorothiazide even if you feel well. Do not stop taking enalapril and hydrochlorothiazide without talking to your doctor.
