high blood pressure
"Been on terazosin for 3 months for blood pressure.  My blood pressure went from 165/95 to 220/125. I also take a beta blocker, spirolactone and coversyl.  Did the opposite of what it was supposed to do.  Felt nauseous the entire time and almost fainted numerous times.  This drug had the adverse reaction for me and was a very difficult 3 months.  I'm back on amlodimine and my blood pressure has returned to normal.  Anyone else with similar experience?"
