Tamsulosin, sold under the trade 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, sleepiness, 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. Specifically it is an α1 adrenergic receptor blocker.

Tamsulosin was approved for medical use in the United States in 1997. It is available as a generic medication and in combination with dutasteride or solifenacin. In the United States, the wholesale cost per dose is less than US$0.10 as of 2018. In the United Kingdom, it costs the NHS 0.04 pounds per dose as of 2021. The modified-release version does not have any particular advantage. In 2017, it was the 35th most commonly prescribed medication in the United States, with more than 20 million prescriptions.
