high blood pressure
"I have been taking Bystolic 5mg 2x a day for the last 2 years.  I was 33 yrs old when I discovered my blood pressure was high (150/105 approx) ouch. I don't have any of the risk factors for high blood pressure.  Dr said it is probably just genetic.  My blood pressure has been controlled and has been normal ever since I started taking Bystolic.  I have not had any negative side effects at all."
