Warnings
This drug can cause serious (possibly fatal) harm to an unborn baby if used during pregnancy. Therefore, it is important to prevent pregnancy while taking this medication.

Uses
This drug is used to treat high blood pressure (hypertension). This medication is a combination of two drugs (an angiotensin receptor blocker and a thiazide "water pill"/diuretic). Losartan blocks the hormone angiotensin thereby relaxing blood vessels, causing them to widen. The thiazide diuretic increases the amount of urine you make, therefore decreasing excess water and salt in your body. High blood pressure reduction helps prevent strokes, heart attacks, and kidney problems.

OTHER USES:
This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
This drug may also be used to treat congestive heart failure and to help protect the kidneys from damage due to diabetes. Losartan has been used to lower the risk of strokes in patients with high blood pressure and an enlarged heart.
