Brand Name: Hyzaar
Generic Name: hydrochlorothiazide and losartan
Uses and Indications
Hyzaar contains a combination of hydrochlorothiazide and losartan. Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.
Losartan is a angiotensin II receptor antagonist. Losartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.
Hyzaar is used to treat high blood pressure (hypertension). It is also used to lower the risk of stroke in certain people with heart disease.
Safe usage and general guidance
Take Hyzaar exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results from this medication.
Take Hyzaar with a full glass (8 ounces) of water.
Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking Hyzaar, which can lead to severely low blood pressure or a serious electrolyte imbalance.
To be sure this medication is helping your condition, your blood pressure will need to be checked on a regular basis. Your kidney function may also need to be tested. Do not miss any scheduled appointments.
Hydrochlorothiazide can interfere with the results of a thyroid test. Tell any doctor who treats you that you are using Hyzaar.
If you are being treated for high blood pressure, keep using Hyzaar even if you feel fine. High blood pressure often has no symptoms.
Store Hyzaar at room temperature away from moisture and heat.

Hyzaar can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert. Avoid drinking alcohol. It can lower your blood pressure and may increase some of the side effects of Hyzaar.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.
Do not use potassium supplements or salt substitutes while you are taking Hyzaar, unless your doctor has told you to. In rare cases, Hyzaar can cause a condition that results in the breakdown of skeletal muscle tissue, leading to kidney failure. Call your doctor right away if you have muscle pain, tenderness, or weakness especially if you also have fever, nausea or vomiting, and dark colored urine.
