Tamsulosin is an alpha-blocker used to treat complications associated with an enlarged prostate and difficulty urinating. Tamsulosin is a category B drug, with no evidence of health risks posed to either pregnant women or humans. Tamsulosin works by relaxing the prostate and helping the flow of urine from the bladder. Although Tamsulosin can temporarily treat the symptoms of an enlarged prostate, it cannot help an individual avoid surgery.
