My blood pressure is around 145/90 and i am taking 50mg of Triamterene. Because my blood pressure is elevated, my doctor wants to put me on Lisinopril 10mg. The pharmacy warned about the medications both causing potassium levels to raise to unhealthy levels and to double check with my doctor. I did, and they still say it s okay to take it even though the things I read on the net and what the pharmacy told me were negative. I am 27 years old and am already half way through the process of getting the gastric bypass, if I change doctors now then the whole process will be screwed. If I continue to take the Triamterene and not start this new drug, then how long approximately will I see positive results if I try to lower the bloodpressure though diet/exercise. I am wondering on average if you see results in weeks or months because I don t trust this pill nor the doctor seeing that I was already in the emegency room last weekend because he had me on something else that didn t work. The Linsinopril is a small dose though so I am wondering if it also makes a huge difference
