IMPORTANT WARNING:  

Why is this medication prescribed?  

Losartan is used alone or in combination with other medications 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.

How should this medicine be used? 

Losartan comes as a tablet to take by mouth. It is usually taken once or twice a day with or without food. To help you remember to take losartan, 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 exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Losartan controls high blood pressure but does not cure it. Continue to take losartan even if you feel well. Do not stop taking losartan without talking to your doctor.
