Are Zebeta and Tenormin the Same Thing?

Zebeta (bisoprolol fumarate) and Tenormin IV Injection (atenolol) are beta-adrenergic receptor blocking agents (beta-blockers) used to treat hypertension (high blood pressure).

Tenormin IV Injection is also used to treat angina, for management of acute myocardial infarction and occasionally for thyroid storm management.

Side effects of Zebeta and Tenormin IV that are similar include tiredness/fatigue, slow heartbeat, lightheadedness, dizziness, dry mouth, constipation, weakness/lethargy, sleep problems (insomnia), and depression.

Side effects of Zebeta that are different from Tenormin IV include drowsiness, spinning sensation, nausea, vomiting, stomach pain, diarrhea, increased urination, runny or stuffy nose, ringing in your ears, anxiety, restless feeling, joint or muscle pain, itching or skin rash, or loss of interest in sex.
