Tamsulosin Hydrochloride Drug Information

• Flomax Overview

  Tamsulosin is used by men to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia-BPH). It does not shrink the prostate, but it works by relaxing the muscles in the prostate and the bladder. This helps to relieve symptoms of BPH such as difficulty in beginning the flow of urine, weak stream, and the need to urinate often or urgently (including during the middle of the night). Tamsulosin belongs to a class of drugs known as alpha blockers. Do not use Flomax to treat high blood pressure.
