GENERIC NAME(S): Bisoprolol-Hydrochlorothiazide
OTHER NAME(S): Ziac Tablet
If you have chest pain (angina) or heart disease (such as coronary artery disease, ischemic heart disease, high blood pressure), do not stop using this drug without first consulting your doctor. Your condition may become worse when the drug is suddenly stopped. If your doctor decides you should no longer use this drug, you must gradually decrease your dose according to your doctor's instructions.
When gradually stopping this medication, it is recommended that you temporarily limit physical activity to decrease strain on the heart. Seek immediate medical attention if you develop: worsening chest pain, tightness or pressure in the chest, chest pain spreading to the jaw/neck/arm, sweating, trouble breathing, or fast/irregular heartbeat.Show More
This product contains two medications. Bisoprolol is a beta blocker that works by blocking the effect of certain natural chemicals (such as epinephrine) on the heart and blood vessels. This slows your heartbeat, lowers blood pressure, and reduces strain on the heart. Hydrochlorothiazide is a "water pill" (diuretic) that works by increasing the amount of urine that you make. This causes your body to get rid of extra salt and water, which probably helps to relax the blood vessels so that blood can flow more easily. These two drugs are used together when one medication is not controlling your blood pressure. Using these two drugs together can also reduce the amount of each drug you must take, thereby decreasing the chances of side effects.
