There are many different "basic" types of BP medicines... For anyone taking medication for high blood pressure, it might be worthwhile to learn what kind of drug you are taking, and important to understand what it might be doing to lower your blood pressure.
First of all, do you know what kind of medication? Which of these categories does it fit into?
Angiotensen II receptor blockers
Calcium channel blockers
Alpha-2 Receptor Agonist
Combined alpha and beta blockers
Peripheral adrenergenic inhibitors
Blood vessel dilators, or vasodilators
Secondly... do you know what your medication actually does to lower your BP?
Third... what are the side effects?... short term? long term?
Why did your doctor prescribe the medication you are taking, and not some other type?
Results usually equate to success, but there are other considerations... Cost in $$$, overkill... resulting in lower BP, but covering up other bad habits that may have longer lasting effects... not just overeating, but masking the effects of smoking, alcohol, or other destructive lifestyles: ie...
a neighbor bragged about his "healthy" blood pressure, but died from cirrhosis of the liver.
ACE inhibitors such as lisinopril, have a possible side effect on the kidneys, which might require periodic testing to prevent damage, or to possibly change to a different medication.
As with anything else that deals with our physical health, there aren't always simple answers. If BP was simply a matter of salt, carbs, weight, exercise or a special diet, then that would be the magic cure for all. In the case of those taking medication, taking the time to understand what your medicine does, and how it works, could pay off over the longer term...
