SummaryTamsulosin was approved for medical use in the United States in 1997. Specifically it is an α1 adrenergic receptor blocker. Tamsulosin, sold under the brand name Flomax among others, is a medication used to treat symptomatic benign prostatic hyperplasia (BPH) and chronic prostatitis and to help with the passage of kidney stones. The evidence for benefit with a kidney stone is better when the stone is larger. It is taken by mouth. Common side effects include dizziness, headache, sleeplessness, nausea, blurry vision, and sexual problems. Other side effects may include feeling lightheaded with standing and angioedema. Tamsulosin is an alpha blocker and works by relaxing muscles in the prostate. |
