Tamsulosin is an oral medication used to treat symptomatic benign prostatic hyperplasia (BPH) and chronic prostatitis and to help with the passage of kidney stones. The evidence for benefit with a kidney stone is better when the stone is larger.
Common side effects include dizziness, headache, insomnia, nausea, blurry vision, and sexual dysfunction.
Other side effects may include feeling lightheaded with standing and angioedema. Tamsulosin is an alpha-blocker and works by relaxing muscles in the prostate. Specifically, it is an α1 adrenergic receptor blocker.
