Bystolic (Nebivolol) Side Effects, Important Information, How to Take & Before Taking

Bystolic belongs to a category of drugs called beta blockers that work by reducing the heart rate and decreasing the load on the heart. It is a prescription drug prescribed majorly to individuals suffering from high blood pressure. Bystolic, also known as Nebivolol, functions by blocking the action of certain naturally occurring elements in the human body known as epinephrine on the heart and various other blood vessels in the body. It also lowers its impact on heart muscles which otherwise rapidly contract and expand upon its secretion. The medicine usage results in muscle relaxation and reduction in the workload on the heart, thus resulting in lower risk of stroke, heart attack, angina, etc.
