What is Flomax

Tamsulosin

The Generic name of this drug

Treatment Summary

Tamsulosin is a drug used to treat an enlarged prostate. It works by blocking certain receptors in the prostate and bladder, causing the muscles in these areas to relax. This relaxation allows for better urinary flow. It was approved by the FDA in 1997 and is more selective than other similar drugs, meaning it is less likely to cause a drop in blood pressure.

Effectiveness

How Flomax Affects Patients

Tamsulosin is a drug that blocks the actions of certain alpha-1A and alpha-1D hormones, which are commonly found in the prostate and submaxillary tissue. This drug binds to these hormones more strongly than it does to alpha-1B hormones, found in the aorta and spleen. This makes it effective in improving urinary flow while having less adverse side effects like low blood pressure.

How Flomax works in the body

Tamsulosin is a medication that helps reduce symptoms of an enlarged prostate. It does this by blocking certain receptors in the prostate, specifically alpha-1A and alpha-1D. Blocking these receptors causes the smooth muscle in the prostate to relax, improving urinary flow. It also relaxes the muscles in the bladder, reducing the storage symptoms of an enlarged prostate. Tamsulosin is designed to be specific to the target area to minimize effects elsewhere in the body.

Flomax Toxicity & Overdose Risk

Taking too much tamsulosin may cause low blood pressure and patients should lie down in order to maintain their heart rate and pressure. If more help is needed, intravenous fluids or vasopressors may be administered and kidney function should be monitored. Dialysis is not effective as the drug binds to protein. Tamsulosin is not meant for use in women and has not been studied in pregnancy, though animal studies have not shown any signs of harm. Male and female fertility may be affected as animals have shown impairment of ejaculation, fertilization, and abnormal ejaculation in men. Tamsulosin has been

Flomax for Enlarged Prostate with Urination Problems

This treatment works great for me. If I miss even one or two doses, it's really difficult for me to urinate. I'm hopeful that there will be a long-term solution found eventually, but until then, this is a great stopgap measure.

While this drug did alleviate the original issue, it unfortunately also came with a range of negative side effects that made it unusable for me. These included everything from an increased heart rate to depression and insomnia.

Flomax for Stones in the Urinary Tract

Though it did alleviate the pressure on my bladder, I unfortunately could not use this drug because it caused my heart rate to increase significantly. Additionally, I felt irritable and depressed while using this medication and had difficulty sleeping; after trying it twice, I decided to speak with my doctor about alternatives.

Flomax for Enlarged Prostate with Urination Problems

I've been taking this for seven years, and my doctor recently upped the dosage to two per day. This worked fine until Rite Aid switched to a different generic 0.4mg capsule with a D 53 on it. Since then, I've had issues urinating; I wake up four or five times a night to use the bathroom, but only produce a tiny amount of urine each time. Additionally, during sex there is almost no semen ejaculated and orgasm is significantly less intense.

Flomax for Enlarged Prostate with Urination Problems

I've been taking this medication for seven years and, unfortunately, have experienced some negative side effects in recent months. Ever since my pharmacy changed the generic brand they use, I've had difficulty urinating and often wake up several times a night to use the restroom. Additionally, sex has become less enjoyable as I don't produce semen or experienceorgasm like I used to.

Flomax for Stones in the Urinary Tract

This treatment helps me urinate more regularly, which is great for kidney stones. However, the side effects have been a stuffy nose multiple times throughout the day, barely any ejaculate, and feeling worn out by 9pm. I also think it's giving me dark bags under my eyes. Overall it's helping though.

Flomax for Stones in the Urinary Tract

I've been using this medication to help me deal with kidney stones. It's increased my urination frequency, which has been great. However, I've experienced some bothersome side effects like a stuffy nose and reduced ejaculate volume. Additionally, I'm worried it might be causing dark circles under my eyes. Despite all of that, it is helping so I continue to use it.

High Intensity Focused Ultrasound for Benign Prostatic Hyperplasia

Male
New York, NY

Objectives: To assess the efficacy of HIFU therapy for benign prostatic tissue ablation in patients with lower urinary tract symptoms (LUTS) due to bladder outlet obstruction (BOO) that caused by Benign prostatic hyperplasia (BPH). The primary objective of the study is to determine the efficacy of HIFU therapy by assessing the changes in IPSS score in 6-month post HIFU procedure for BPH with compared to baseline. The secondary objectives of this study are as follow: * To assess any adverse events related to the procedure or device. * To assess the operation related characteristics including: total operation time and ablation time required in HIFU procedure for BPH, total catheterization time after the HIFU procedure for BPH, and categorical ablation zone * To assess the patient's post operative pain level at different post op time points. * To assess the urinary flow and symptoms improvement by studying the changes in IPSS, Qmax, and PVR at different post op time points compared to the baseline. * To assess the effectiveness of HIFU by studying the changes in PSA levels, types of medication for BPH or any urologic condition, proportion of patients who are taking BPH medication, prostate volume, and prostate calcification level and the reoperation rate within 12-month post-op. * To assess changes in patients' sexual function at different post op time points. The hypothesis is that a HIFU ablation is a safe and effective treatment for patients with LUTS due to BOO from BPH.

Optilume vs Rezum for Enlarged Prostate

Lower urinary symptoms (LUTS) affect older men and their frequency and severity increase with age. According to Berry et al., the histological diagnosis of benign prostatic hyperplasia (BPH) increases from 25% in the group age between 40 to 49 years to 80% in the group age between 70 to 79 years (1). However, this hyperplasia can lead to a bladder outlet obstruction (BOO) secondary to benign prostatic enlargement (BPE), causing storage and voiding symptoms, associated with a considerable impairment of the quality of life (2). Surgical therapy of BPH has continuously evolved in recent years. The current gold standard for the endoscopic treatment of BPH is the transurethral resection of the prostate (TURP). Other innovative techniques were developed including Urolift, transurethral laser enucleation (holmium, thulium) and Aquablation therapy. One of the latest technologies for the management of BPH are Optilume BPH Catheter System (Optilume®, Urotronic Inc, Minneapolis, USA) and Rezum Water Vapor Therapy (Rezum System, Bostocn Scientific, Marlborough, MA). The purpose of the present study is to compare between patient experience, symptom relief and functional improvement when using the Optilume BPH Catheter System (Optilume®, Urotronic Inc, Minneapolis, USA) and Rezum Water Vapor Therapy (Rezum System, Boston Scientific, Marlborough, MA).
