What is Ziac?

Ziac contains a combination of hydrochlorothiazide and bisoprolol. Hydrochlorothiazide is a thiazide diuretic (water pill). Bisoprolol is a beta-blocker.

Ziac is used to treat high blood pressure (hypertension).

Ziac tablets are available in three different strengths; 2.5 mg/6.25 mg (bisoprolol fumarate 2.5 mg and hydrochlorothiazide 6.25 mg), 5 mg/6.25 mg (bisoprolol fumarate 5 mg and hydrochlorothiazide 6.25 mg), and 10 mg/6.25 mg (bisoprolol fumarate 10 mg and hydrochlorothiazide 6.25 mg).

Warnings

You should not use Ziac if you are unable to urinate. You should not use Ziac if you have a serious heart condition such as "sick sinus syndrome" or "AV block," severe heart failure, or slow heartbeats that have caused you to faint.

Before using Ziac, tell your doctor if you have congestive heart failure, circulation problems, kidney or liver disease, cirrhosis, glaucoma, asthma, bronchospastic lung disease, a thyroid disorder, lupus, gout, diabetes, or a penicillin allergy.

If you are diabetic, check your blood sugar carefully. Using bisoprolol can make it harder for you to tell when you have low blood sugar. Your insulin or diabetic medication needs may change while you are taking Ziac. Talk with your doctor before changing any doses.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.
