Uses For Hyzaar

Losartan and hydrochlorothiazide is a combination medicine that belongs to the class of medicines called high blood pressure medicines (antihypertensives). It is used to treat high blood pressure (hypertension).

High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.

Losartan works by blocking a substance in the body that causes blood vessels to tighten. As a result, losartan relaxes blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart. Hydrochlorothiazide helps reduce the amount of salt and water in the body by acting on the kidneys to increase the flow of urine; this also helps to lower blood pressure.

This combination also may be used for other conditions as determined by your doctor.

This medicine is available only with your doctor's prescription.

It is important that your doctor check your progress at regular visits to make sure that this medicine is working properly and to check for unwanted effects.

Do not take other medicines unless they have been discussed with your doctor. This especially includes potassium supplements or salt substitutes that contain potassium, since they may change your blood potassium levels, or over-the-counter (nonprescription) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may tend to increase your blood pressure.

Dizziness, lightheadedness, or fainting may occur with this medicine. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you experience these effects.

Check with your doctor right away if you become sick while taking this medicine, especially with severe or continuing nausea and vomiting or diarrhea. These conditions may cause you to lose too much water and lead to low blood pressure.

Dizziness, lightheadedness, or fainting may also occur if you exercise or if the weather is hot. Heavy sweating can cause loss of too much water and result in low blood pressure. Use extra care during exercise or hot weather.

Avoid alcoholic beverages until you have discussed their use with your doctor. Alcohol may make the low blood pressure effect worse and/or increase the possibility of dizziness or fainting.

For diabetic patients:

  • Hydrochlorothiazide may raise blood sugar levels. Check with your doctor if any changes in your blood sugar levels occur.
