Nebivolol Generic Uses Side Effects Dosage

nebivolol

Nebivolol is a medication used to lower blood pressure in adults with hypertension and heart failure in adults older than 70 years. Reducing blood pressure reduces the risk for heart attacks and strokes. Nebivolol is a beta-1 selective beta blocker that lowers blood pressure by blocking beta-1 receptors in the heart muscles. Beta blockers, including nebivolol, are used as a second-line therapy for hypertension.

The autonomic nervous system and hormones regulate normal blood pressure and heart rate by controlling heart and blood vessel contraction and relaxation. Norepinephrine and epinephrine, produced by adrenal glands and nerve cells, bind to beta-1 receptors on the heart muscle and stimulate their contraction. During times of stress, more hormones are released, resulting in stronger heart muscle contractions, increased blood pressure, and heart rate.

Nebivolol blocks the effect of norepinephrine and epinephrine by binding to beta-1 receptors. This causes the heart to contract with less force, dilates arteries, and reduces vascular resistance and blood pressure. At doses up to 10 mg, nebivolol acts only on beta-1 receptors. At higher doses, it also blocks beta-2 receptors in the lungs and smooth muscles. Suddenly stopping beta blockers, including nebivolol, can cause heart attacks or sudden death.

Warnings

  • Do not use nebivolol for hypertension if you have hypersensitivity to any component of the formulation or heart rhythm disorders, including severely low heart rate, sick sinus syndrome (unless you have a permanent pacemaker), or heart block greater than first degree.

Pregnancy and breastfeeding

  • Animal reproductive studies indicate nebivolol use during pregnancy may result in pregnancy and delivery complications and fetal harm. However, untreated maternal hypertension may increase the risk of adverse maternal and fetal outcomes.
  • There are no studies of nebivolol use in pregnant women. Nebivolol should only be used in pregnant women with caution if potential benefits outweigh potential risks.
  • It is not known if nebivolol is excreted in breastmilk. Nursing mothers taking nebivolol should avoid breastfeeding because of the potential for serious adverse reactions in the breastfed infant, particularly bradycardia. Agents other than nebivolol are preferred for the treatment of hypertension in nursing mothers.

What else should I know about nebivolol?

  • Take nebivolol as directed, regularly and continuously. If you miss a dose, continue with the next scheduled dose.
  • Do not stop taking nebivolol abruptly. It must be gradually withdrawn under your physician’s supervision to prevent chest pain and/or heart attack.
