Discussions that mention triamterene-hctz

High & Low Blood Pressure board


One of the major problems with loop and thiazide diuretics is that they can cause a profound hypokalemia (low potassium). While the average pt may be able to tolerate this, some people are either very sensitive to the potassium-depleting effects or cannot have low K for other reasons (renal failure, heart conditions, etc). This is when you MUST use something like triamterene. Since many people show low K levels while on HCTZ or furosemide, they have formulated a combination triamterene-HCTZ diuretic that gives you the best of both worlds. I would say that if your meds are working for you and your potassium is not dropping off too much, there is no reason to worry. There is really not much of an difference between them besides the way they work (and not the end result).

Regarding the blood pressure, there is really no such thing as "too low" unless it starts causing symptoms of lightheadedness. I've seen people with resting BPs in the area of 90/50, which is fine as long as they don't have any symptoms from it.
