A question about blood pressure medication?

Buy a electronic blood pressure monitor of find a place where you can get weekly blood pressure checks. Your doctor's office should even provide this service for free if you ask. If you feel lightheaded, especially upon standing, that is a sign of hypotension (low BP).

If it goes back to NORMAL suddenly without you suddenly knowing -- well, that's the point of the medicine, now isn't it. If your blood pressure goes to low, you will feel dizzy and possibly nauseous. CALL YOUR DOCTOR. Home blood pressure machine cost about $50 at Wal-MArt or Sam's club. Go buy one. Good tool to have around. With your history of high blood pressure there is a good chance that you will suffer from high blood pressure at OTHER times in your life. Measure you blood pressure daily. Ask your doctor what "range" you should be in.

Well, first of all I dont think your doctor would proscribe any medication to you which might be harmful ;). Anyway, normally hypertension is treated with so-called beta-blockers, a frequently used substance found within this group is betaprolol (Sold as Bisocard), which to a dose-given degree blocks the effect of the sympathetic nerve system on the heart and certain other structures. The sympathetic division of the nerve system, opposite to the parasympathetic division, work on the cardiovascular system with a pressor-effect (positive ionotropic effect), with other words it increases the pulse (heart frequency) and stroke volume (amount of blood pumped by each contraction). By blocking this effect, we thus lower the above parameters, lowering the blood pressure. Normally pretty low doses are given, and even though its pretty potent, you should normally have no problems. Its not like your BP will go back to the basal level "like that", and the heart have several intrinsic (built-in) possibilities to counter such effects!
