What is Brevibloc?

Brevibloc is a beta-blocker that affects the heart and circulation (blood flow through arteries and veins).

Brevibloc 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.
