What is Brevibloc?

Brevibloc is a beta-blocker that is used to help keep the heart beating normally in people with certain heart rhythm disorders of the atrium (the upper chambers of the heart that allow blood to flow into the heart). This medicine is used in people with atrial fibrillation or atrial flutter.

Brevibloc is also used during surgery to help regulate blood pressure and heart rate.

Brevibloc may also be used for purposes not listed in this medication guide.

Warnings

You should not be treated with Brevibloc if you have a serious heart condition ("sick sinus syndrome" or "AV block"), very slow heartbeats, heart failure, pulmonary hypertension, or if you are receiving certain IV heart or blood pressure medications.

In an emergency, you may not be able to tell caregivers about your health conditions. Make sure any doctor caring for you afterward knows you received Brevibloc.
