What is Tamsulosin?

Tamsulosin is a medication prescribed to alleviate uncomfortable urinary symptoms caused by an enlarged prostate in men (benign prostatic hyperplasia).

Tamsulosin belongs to a group of medicines known as alpha-blockers. Tamsulosin works by relaxing the muscles in the bladder and prostate which enable the passage of urine. This then allows the urine to pass more easily.
