Losartan and Hydrochlorothiazide

Why this is used

The combination of losartan and hydrochlorothiazide is used to treat high blood pressure. Losartan is in a class of medications called angiotensin II receptor antagonists. It works by blocking the action of 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 to take it

The combination of losartan and hydrochlorothiazide comes as a tablet to take by mouth. It is usually taken once a day with or without food. To help you remember to take losartan and hydrochlorothiazide, take it around the same time 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 losartan and hydrochlorothiazide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Losartan and hydrochlorothiazide controls high blood pressure but does not cure it.
