Tamsulosin: Uses, Dosage, Side Effects, and More

Tamsulosin is a prescription alpha-1 adrenergic blocker used to treat the symptoms of benign prostatic hyperplasia, also known as enlarged prostate. It works by relaxing the muscles in the prostate and bladder neck, which helps improve urine flow and reduce symptoms such as difficulty starting urination, weak stream, and frequent urination (especially at night).
