My mother currently taking nebivolol 5mg in morning and amlodipine/perindopril 5/8mg in evening for hypertension. Her blood pressure has recently been improved and taking both pills cause low blood pressure, she is also suffering from cough as a side effect from perindopril. I am considering to shift her to nebivolol only but 5 mg once a day is not controlling the blood pressure well. My question is can nebivolol be taken twice a day in 2.5 mg doses, I am unable to find any medical study using nebivolol twice a day all recommend single dose of 5mg as starting dose, have any of you have experience with taking nebivolol twice a day.
