What is this medication?

LOSARTAN (loe SAR tan) treats high blood pressure. It may also be used to prevent a stroke in people with heart disease and high blood pressure. It can be used to prevent kidney damage in people with diabetes. It works by relaxing the blood vessels, which helps decrease the amount of work your heart has to do. It belongs to a group of medications called ARBs.

This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.
