What Is Losartan Used For?

Losartan is mainly used to:

Lower high blood pressure

Reduce the risk of stroke

Protect the kidneys, especially in people with diabetes

Treat heart failure in some patients

By controlling blood pressure, losartan helps prevent serious problems like heart attacks and kidney damage.

How Does Losartan Work?

Losartan blocks the action of a hormone called angiotensin II, which normally causes blood vessels to tighten. When this hormone is blocked, blood vessels relax, blood pressure drops, and the heart doesn’t have to work as hard.

How Is Losartan Taken?

Losartan is taken by mouth, usually once daily, with or without food. The dose depends on the person’s condition and how well they respond to treatment. It’s important to take it at the same time each day for best results.

Possible Side Effects

Serious side effects are rare, but any unusual symptoms should be reported to a doctor.
