My Urologist prescibed this drug for me after having kidney stones removed, he also said I had a slightly increased prostate. The side effects of this drug are horrendous. I've had dizzines, sore throat, running nose, constipation, insomnia and by far the worst of all is the itching. I have scratched until I have drawn blood. Anti-histamines give no relief. The only way I have obtained some relief from the itching is by holding ice cubes to it. I will never take this drug again no matter what!
