What is Ziac?Ziac is a blood pressure lowering medication that contains two different medicines: bisoprolol fumarate and hydrochlorothiazide. These two medications work together to lower blood pressure in people who did not have enough blood pressure lowering from other medications.
What is the most important information I should know about Ziac?Ziac may mask the signs and symptoms of low blood sugar, especially in diabetics. If you have diabetes, monitor your blood sugar frequently, especially when you first start taking Ziac. Signs of low blood sugar may include a rapid heartbeat, anxiety, sweating, weakness, dizziness, drowsiness, faintness, vision changes, headache, chills, tremors, or an increase in appetite. Ask your doctor before you change the dose of your diabetes medicine.
Ziac may also mask the signs of an underlying thyroid disorder such as rapid heart rate.
This medication may alter the levels of electrolytes (important elements and minerals) in your blood. It is important to stay hydrated while taking Ziac.
Do not drive or perform other possibly unsafe tasks until you know how you react to Ziac; this drug may cause dizziness, light-headedness or fainting. These effects may be worse if you take it with alcohol or certain medicines. Hot weather, exercise, or fever may also increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
Patients who take medicine for high blood pressure often feel tired or run down for a few weeks after starting treatment. Be sure to take your medicine even if you may not feel "normal." Tell your doctor if you develop any new symptoms.
Tell your doctor or dentist that you take Ziac before you receive any medical or dental care, emergency care, or surgery.

You should not take Ziac if you are allergic or sensitive to Ziac or any of its ingredients.
What should I tell my doctor before I take the first dose of Ziac?Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Ziac.

Tell your doctor if you have a history of anaphylactic reactions to allergens, because Ziac may decrease the effectiveness of epinephrine.

Adults: The usual starting dose is 2.5/6.25 milligrams (mg) taken once a day (equivalent to 2.5 mg of bisoprolol fumarate and 6.25 mg of hydrochlorothiazide).
