What Brevibloc Injection is used for

Irregular heartbeat, also known as arrhythmia, means that there is a disturbance of the heart's normal rhythm or beat. Arrhythmia may be caused by a number of factors, including some heart diseases, an overactive thyroid gland, or chemical imbalances. Brevibloc Injection helps restore the heart's normal rhythm.
Brevibloc Injection belongs to a group of medicines called beta-blockers.
Ask your doctor if you have any questions about why Brevibloc Injection has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor’s prescription.
There is not enough information to recommend the use of Brevibloc Injection in children.
