Gosh I know so many divers that take BP meds I am probably the only one that doesn’t. They just dont mention it. It would be bad if you were not in tune to your own medical health however and had high BP and didnt take meds but if you know your is under control then you should not have any problems. By the way these people taking BP meds dive alot. You do have to watch that your Bp med does not contain a diuretic or if it does you need to drink double the water!! You should ask your pharmacist next time you refill or you might be able to get that info online.
