For Benign Prostatic Hyperplasia "Doxazosin has been excellent for decreasing nighttime bathroom trips from around 4 to 1. But it has caused heart palpitations and raised my pulse rate from around 55 to 68. Also made me mentally and physically sluggish over time, so discontinued use."

For Benign Prostatic Hyperplasia "I'm taking 2 mg of Doxazosin, and it increased my urine flow and decreased my trips to the bathroom. It also reduced my blood pressure from 150/60 to 130/60. I increased my dosage to 4 mg in an attempt to reduce my blood pressure even more, but the side effects (fatigue, headaches, blurry vision) were too extreme, so I decreased my dosage back to 2 mg. I experience no side effects at the 2 mg dosage. Overall, I think this is a fine drug for men with benign prostatic hyperplasia and mildly/moderately high blood pressure."

For High Blood Pressure "I have historically had higher blood pressure (BP), normally in the mid-130s, though in the doctor's office, it can increase to the 150s. I am 75 and have been on amlodipine and irbesartan for over 10 years and tolerated it well. My doctor recently added doxazosin 1 mg once a day. Within 3 weeks, side effects became more evident, e.g., headache, dizziness, lightheadedness, and fatigue. I was advised by my doctor to stop taking it. I have been off the medication for 48 hours and am feeling better with decreasing side effects. Still a little light-headed and tired. BP is in my typical mid to high 130s. Doxazosin is not well tolerated by my body. Still on amlodipine and irbesartan. I think I should work on weight reduction versus adding another BP med. I am 195 lbs and will try to get to 180 by year-end."

For Benign Prostatic Hyperplasia "Doxazosin was effective in relieving BPH symptoms, but suffered from many side effects: retrograde ejaculation, extreme fatigue, dizziness, constipation. Brutal side effects. Just switched to Alfuzosin. Hope that works better."
