OT
Perhaps, as you say, Dr knows best, but from my own experience, I would be wary of Amlodipine. My BP was "borderline" and erratic for some time, then the Doc decided that it needed to be controlled. Initial dosage of 2mg gave no problems but when increased to 4mg, gave problems with whole body skin rashes and very swollen ankles. Now on 4mg Doxazosin, and rashes have gone but I still have swollen ankles, which Doc says is a lasting effect of Amlodipine.
Try a Google on the side effects and its availability ( or otherwise) in Holland.
