Ziac® (as a combination product containing Bisoprolol, Hydrochlorothiazide)
WHY is this medicine prescribed?
Bisoprolol is used alone or in combination with other medications to treat high blood pressure. Bisoprolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve and decrease blood pressure.
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.
HOW should this medicine be used?
Bisoprolol comes as a tablet to take by mouth. It is usually taken once a day. To help you remember to take bisoprolol, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take bisoprolol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of bisoprolol and gradually increase your dose.
Bisoprolol controls high blood pressure but does not cure it. It may take a few weeks before you feel the full benefit of bisoprolol. Continue to take bisoprolol even if you feel well. Do not stop taking bisoprolol without talking to your doctor. Suddenly stopping bisoprolol may cause angina (chest pain), heart attack, or irregular heartbeat. Your doctor will probably decrease your dose gradually.
Are there OTHER USES for this medicine?
Bisoprolol also is used sometimes to treat heart failure. Talk to your doctor about the possible risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
