How Tamsulosin Works

In men with an enlarged prostate, the prostate can press against the urethra and make urination difficult.

Tamsulosin blocks alpha-1 receptors in the prostate and bladder area, helping:

• Relax prostate muscles.
• Relax bladder outlet muscles.
• Improve urine flow.
• Reduce difficulty starting urination.

It does not shrink the prostate but helps relieve urinary symptoms.
