Ken has been experiencing a little big of dizziness/lighthead when getting out of bed in the mornings. He has taken his blood pressure last couple mornings (before getting out of bed) and it has been 98/59 and 99/61. During the day/evenings, he has gotten readings of around 115/70 last couple of days.
He has high blood pressure that is controlled with benazapril (takes it at night) and "normal" for him on Benazapril is 120-130/80.
I looked up cialis and it says it can cause sudden drops in blood pressure with nitrates or beta-blockers, but I believe benazapril is an ACE inhibitor not a beta blocker.
Seems if he just sits a minute before getting out of bed in morning, he is ok with dizziness. Has anyone else expected decreases in blood pressure on cialis with benazapril? Should this be a concern?
