About Ziac (Bisoprolol-Hydrochlorothiazide)

How does it work?

Ziac contains two drugs that help lower blood pressure. Bisoprolol is a beta-blocker that slows down the heart rate. Hydrochlorothiazide is a diuretic (“water pill”) that helps the body get rid of excess salt and water. Together, decrease the amount of fluid in the blood vessels and reduce the workload on the heart.

What does it treat?

Ziac is used to treat high blood pressure (hypertension). This also lowers the risk of related complications, like heart disease, stroke, heart attack, kidney failure and vision loss.

What forms does it come in?

This hypertension medicine comes as a tablet that’s taken by mouth. Don’t stop taking it, even if you’re feeling better. This could cause a dangerous spike in your blood pressure.

Ziac vs. Bisoprolol-Hydrochlorothiazide

Ziac is a brand name and Bisoprolol-Hydrochlorothiazide is the generic version. Both contain Bisoprolol, a beta-blocker, and Hydrochlorothiazide, a diuretic. Brand drugs can be more expensive, depending on your insurance.

High blood pressure is a long-term (chronic) condition that can harm your organs. Medications for blood pressure are not a one-time cure. This medicine doesn't provide a complete cure for high blood pressure, so it's important to continue taking it, even if you start feeling better. If you stop taking it suddenly, this could cause dangerous problems, like heart attack or stroke. Follow your medical provider's instructions carefully.

What happens if I miss a dose?

If you miss a dose of your blood pressure medicine, take it as soon as you remember. If it's close to the time for your next dose, skip the missed one. Don’t take extra to catch up.

What happens if I take too much?

Taking too much of your hypertension medicine can lead to serious problems, like very low blood pressure, hypoglycemia (low blood sugar), slow heart rate and electrolyte imbalances.

If you’ve taken too much Ziac, call your health care professional or local poison control center (800-222-1222) immediately.

Can I get Ziac (Bisoprolol-Hydrochlorothiazide) online?

Dr. B offers convenient virtual consultations for hypertension. If you need a refill of your blood pressure medicine, just fill out a short health questionnaire about your medical history. If appropriate, a medical provider will send a prescription to your preferred pharmacy.
