Reserpine
If you take atenolol with reserpine, your
 blood pressure may decrease too much or your heart rate may slow dramatically. This can cause symptoms such as a spinning sensation (vertigo), lightheadedness, dizziness, or fainting. If atenolol and reserpine are taken together, your healthcare provider may choose to monitor your situation more closely and/or adjust your dose of these medicines.
