🔀 Nebivolol with other medicines, food and alcohol

The label says to discuss these with your doctor or pharmacist

  • Reserpine, guanethidine, or clonidine may cause an excessive drop in nervous system activity. The label says clonidine should be stopped gradually only after nebivolol has been stopped for several days.
  • Digitalis glycosides (heart medicines such as digoxin) can add to the slowing of heart rate and increase the risk of a slow heartbeat.
  • Verapamil-type or diltiazem-type calcium channel blockers can cause excessive drops in heart rate, blood pressure, and heart contractility. The label says your doctor may monitor your heart rhythm (ECG) and blood pressure.
  • Disopyramide and other antiarrhythmic medicines may add to the effects of nebivolol on the heart.
  • Do not use nebivolol with other beta-blockers, according to the label.
