Before taking

While taking

Guanabenz is used to treat high blood pressure. It works by decreasing your heart rate and relaxing the blood vessels so that blood can flow more easily through the body.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Guanabenz comes as a tablet to take by mouth. It usually is taken twice a day at evenly spaced intervals. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take guanabenz exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Guanabenz controls high blood pressure but does not cure it. Continue to take guanabenz even if you feel well. Do not stop taking guanabenz without talking to your doctor.

Abruptly stopping guanabenz may increase blood pressure and cause unwanted side effects.
