This drug is used to treat high blood pressure. It is also used to lower the risk of strokes in patients with high blood pressure and an enlarged heart. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This product contains two medications: losartan and hydrochlorothiazide. Losartan is an angiotensin receptor blocker (ARB) and works by relaxing blood vessels so that blood can flow more easily. Hydrochlorothiazide is a “water pill” (diuretic) that causes you to make more urine, which helps your body get rid of extra salt and water.

How to Use

Read the Patient Information Leaflet if available from your pharmacist before you start taking losartan/hydrochlorothiazide and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually once daily with or without food. If this medication causes you to urinate more frequently, it is best to take it at least 4 hours before your bedtime to prevent having to get up to urinate.

If you also take certain drugs to lower your cholesterol (bile acid-binding resins such as cholestyramine or colestipol), take losartan/hydrochlorothiazide at least 4 hours before or at least 4 to 6 hours after these medications.

The dosage is based on your medical condition and response to treatment.
