MANAGEMENT: Close monitoring for clinical response and tolerance is recommended whenever verapamil is added to or discontinued from an antidepressant regimen. Patients should be advised to notify their physician if they experience excessive antidepressant effects such as dry mouth, blurry vision, irregular or fast heartbeat, constipation, urinary retention, dizziness, or orthostatic hypotension. Dose adjustments may be necessary.
