My dad is 87 and has been prescribed 2 1/2 mg of amlodipine a day.  However, he takes his blood pressure several times a day and takes a pill every time the bp is 135 on the top number.  Sometimes he has taken 3 pills in a day.  Is this dangerous?  He went to a cardiologist yesterday who said his heart is in great shape for a man his age.
Hi. For your dads age the upper part of 135 is acceptable. Once a day preferably in the morning should do. Continue to monitor his pressures. If the pressures are not under control then a nigh dose can be added.
