I'm wondering about continuing with corbis bisoprolol 5 mg, which I've been taking for a decade now. My blood pressure is normal, and my pulse is hanging around 60. I'm aware that bisoprolol can lower heart rate, and even though I'm not experiencing any issues, I'm curious whether I should consult a doctor about switching medications because of the lower pulse rate. How long is it generally okay to stay on corbis if I'm not having any problems?
