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.

How should I take Ziac?
Take Ziac exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.
Call your doctor if you are sick with vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking Ziac. This can lead to very low blood pressure, a serious electrolyte imbalance, or kidney failure.
Your blood pressure will need to be checked often. Your blood and urine may both be tested if you have been vomiting or are dehydrated.
If you are diabetic, check your blood sugar carefully. Taking bisoprolol may make it harder for you to tell when you have low blood sugar. Your insulin or diabetes medication needs may change while you are taking Ziac. Do not change your medication dose or schedule without your doctor's advice.
If you need surgery or medical tests, tell the doctor you currently use this medicine. You may need to stop for a short time.
Do not skip doses or stop using Ziac suddenly. Stopping suddenly may make your condition worse. Follow your doctor's instructions about tapering your dose.
Keep using this medicine as directed, even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life.
Store at room temperature, away from heat and moisture. Keep the bottle tightly closed when not in use.
