Hyzaar

Pronounced: HIGH-zahr
Generic ingredients: Losartan potassium and Hydrochlorothiazide

Why is Hyzaar prescribed?

Hyzaar is a combination medication used in the treatment of high blood pressure. One component, losartan, belongs to a new class of blood pressure medications that work by preventing the hormone angiotensin II from constricting the blood vessels, thus allowing blood to flow more freely and keeping the blood pressure down. The other component, hydrochlorothiazide, is a diuretic that increases the output of urine, removing excess fluid from the body and thus lowering blood pressure.

Most important fact about Hyzaar

You must take Hyzaar regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Hyzaar, and you must continue taking it even if you are feeling well. Hyzaar does not cure high blood pressure; it merely keeps it under control.

How should you take Hyzaar?

Hyzaar may be taken with or without food. Take Hyzaar exactly as directed. Try to take it at the same time each day so that it is easier to remember.

--If you miss a dose...

Take the forgotten dose as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule.

--Storage instructions...

Keep in a tightly closed container at room temperature. Protect from light.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Hyzaar.

• Side effects include:
  Dizziness, upper respiratory infection

Why should Hyzaar not be prescribed?

If you have ever had an allergic reaction to losartan, hydrochlorothiazide, or sulfa drugs, you should not take this medication. If you are unable to urinate, do not take Hyzaar.

Special warnings about Hyzaar

If you are taking Hyzaar and have kidney disease, your doctor will watch your kidney function carefully.

Hyzaar can cause low blood pressure, especially if you are also taking another diuretic. You may feel light-headed or faint, especially during the first few days of therapy. If these symptoms occur, contact your doctor. Your dosage may need to be adjusted or discontinued. If you actually faint, stop taking the medication until you have talked to your doctor.
