Patient Education

Hydrochlorothiazide


Hydrochlorothiazide is used alone or in combination with other medications to treat high blood pressure. Hydrochlorothiazide is used to treat edema (fluid retention; excess fluid held in body tissues) caused by various medical problems, including heart, kidney, and liver disease and to treat edema caused by using certain medications including estrogen and corticosteroids. Hydrochlorothiazide is in a class of medications called diuretics ('water pills'). It works by causing the kidneys to get rid of unneeded water and salt from the body into the urine. High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.

Irbesartan


Irbesartan is used alone or in combination with other medications to treat high blood pressure. It is also used to treat kidney disease caused by diabetes in patients with type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood) and high blood pressure. Irbesartan is in a class of medications called angiotensin II receptor antagonists. It works by blocking the action of certain natural substances that tighten the blood vessels, allowing the blood to flow more smoothly and the heart to pump more efficiently. High blood pressure is a common condition, and when not treated it can cause damage to the brain, heart, blood vessels, kidneys, and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.

Blood Pressure Medicines


High blood pressure, also called hypertension, usually has no symptoms. But it can cause serious problems such as stroke, heart failure, heart attack and kidney failure. If you cannot control your high blood pressure through lifestyle changes such as losing weight and reducing sodium in your diet, you may need medicines.

Blood pressure medicines work in different ways to lower blood pressure. Some remove extra fluid and salt from the body. Others slow down the heartbeat or relax and widen blood vessels. Often, two or more medicines work better than one.
