BISOPROLOL/HYDROCHLOROTHIAZIDE - ORAL
COMMON BRAND NAME(S): Ziac
WARNING: If you have chest pain (angina) or heart disease (e.g., 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.
USES: This combination medication is used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.
This product contains two medications. Bisoprolol is a beta blocker that works by blocking the effect of certain natural chemicals (e.g., 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.
HOW TO USE: See also Warning section.
Take this medication by mouth with or without food, usually once daily as directed by your doctor.
The dosage is based on your medical condition and response to therapy.
It is best to avoid taking this medication within 4 hours of your bedtime to avoid having to get up to urinate. Consult your doctor or pharmacist if you have questions about your dosing schedule.
Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time each day. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. It may take up to 3 weeks before you get the full benefit of this drug.
Inform your doctor if your condition worsens (e.g., your routine blood pressure readings increase).
SIDE EFFECTS: See also Precautions section.
Dizziness, lightheadedness, tiredness, and drowsiness may occur as your body adjusts to the medication. Nausea, stomach upset, diarrhea, cough, constipation and trouble sleeping may also occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

This product may reduce blood flow to your hands and feet, causing them to feel cold. Smoking may worsen this effect. Dress warmly and avoid tobacco use.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if you have any of these unlikely but serious symptoms of dehydration: very dry mouth, extreme thirst, muscle cramps/weakness, fast heartbeat, severe dizziness, unusual decrease in the amount of urine, fainting, seizures.
