high blood pressure
"I recently switched physicians and was placed on Bystolic after being on Benicar for over a year.  Benicar did not control my blood pressure; but since being placed on Bystolic I felt the difference immediately.  I had problems with palpitations, uncontrolled blood ptressure, sweating, hot flashes, and racing heart.  I am now much calmer and my blood pressure is under control.  The only side effect I am having (after being on this preescription for a week) is tiredness and a loss of appetite.  I do get a little dizzy about an hour after taking the medication, but Benicar did the same."
