Benign Prostatic Hyperplasia
"Terazosin controls my somewhat high blood pressure and moderately improves my benign prostatic hyperplasia symptoms at 5mg, 3X/day.  I have found that just missing one dose (after 8-10 hrs after last dose) reduces urinary flow rate, but still a bit above flow before taking this medicine.  I am not experiencing any significant side effects, unless I take terazosin in conjunction with muscle relaxant for arthritis pain in back and neck pain. Then I have experienced some dizziness and low blood pressure. I have read that it may take a couple of months before full effects on urinary symptoms occur.  I have been taking terazosin for about 1-1/2 months at this dosage with little difference in the past month in flow.
I previously tried doxazosin and tamsulosin with allergic side effects."
