Saw my family doctor today about my hypertension, for which she has prescribed me diltiazem. This is instead of a thiazide-class diuretic or ACE inhibitor, because I’m worried about them interacting with the piroxicam, which is almost certainly the culprit: my blood pressure was fine until I started taking it. This is, in other words, secondary rather than essential hypertension. A side effect. I’ll start on the diltiazem tomorrow and keep monitoring things until my annual physical in February.
