For Benign Prostatic Hyperplasia "Been using Flomax for several years. I’m 70. My U Dr told me to stop taking Flomax four to six weeks before my next appt. To test/measure the results of the long-term use of it. Nine months ago, he started me on Finasteride 5 mg. Since stopping Flomax cold turkey, I’m very weak, stuffy nose, back pain. Can’t urinate completely, pee runs out several seconds later. I end up standing there waiting, and several streams expel in two or three intervals. Night sweats. Face flushing during the day."

For Benign Prostatic Hyperplasia "Flomax (Tamsulosin hydrochloride) helped me to urinate normally. It did make me feel very tired and weak. I was taking one 0.4 mg a day. I started taking it with breakfast, but switched to taking it after dinner. That helped with most of the tiredness."

For Urinary Tract Stones "I am a 42-year-old woman. I was prescribed Flomax for kidney stones. I have been on this for almost 2 weeks, but I just can't take the side effects anymore. My head and neck hurt so bad, and it will not go away no matter what I do. I feel dizzy, weak, and very 'winded', it seems hard to catch my breath. I feel in a catch-22 because it helps the urine flow, but I just feel so awful otherwise... ???"

For Benign Prostatic Hyperplasia "I have been taking Flomax for a month for Benign Prostatic Hyperplasia. I had been getting up to urinate 2 or 3 times a night, suffering from severe pain during urination. Since starting Flomax, I have found myself dizzy if getting up quickly, blurred vision, decreased sex drive with abnormal ejaculate. I have lower back pain. I feel weaker and tired all the time. On the upside, I can go all night with no need to get up to urinate, and the pain while urinating is 50 percent less."

For Benign Prostatic Hyperplasia "I have been using Flomax (0.4 mg 1/day) for approximately 2 weeks, with a great improvement after the 2nd pill. My problem with urination wasn't too bad to begin with - slow start, weak stream, start/stop, up 2-3 times per night -- just inconvenient. I have experienced side effects with Flomax: get very dizzy when first standing up within 3-4 hours after taking the pill (feels like I'm going to pass out), so I take it at night; noticeable muscle weakness, but not severe. Also, sex is affected, weak orgasm. I tried Saw Palmetto (2,000 mg/day)--seemed to help some, but not very much."

For Benign Prostatic Hyperplasia "I don't know if this medicine would have worked or not because after three days, I was so weak and dizzy from low blood pressure that I stopped taking it. Better to get up 1-2 times a night to pee than pass out from walking across the house. If you have low-to-normal blood pressure, watch out. Also tried doxazosin/Cardura before this with similar results."

For Benign Prostatic Hyperplasia "I was prescribed Flomax due to kidney stones. Other than the pain, I felt fine, then started taking this drug. Long story short, I hate it. I took it for about a week. I suppose it might have helped remove the stone, but I felt like crap. Insomnia, weakness, coughing, hiccuping constantly. Loss of appetite, foods just didn't appeal at all, muscle pain, diarrhea. Thursday was my last pain, today is Monday. I stopped taking them last Saturday. I could not take another one. How anyone can be on these for weeks and months is beyond me."
