Silodosin is used in men to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia; BPH), which include difficulty urinating (hesitation, dribbling, weak stream, and incomplete bladder emptying), painful urination, and urinary frequency and urgency. Silodosin is in a class of medications called alpha-blockers. It relieves the symptoms of BPH by relaxing the muscles of the bladder and prostate.
Silodosin comes as a capsule to take by mouth. It is usually taken with food once a day. Do not take silodosin on an empty stomach. Take silodosin at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take silodosin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Silodosin controls the symptoms of BPH but does not cure it. Continue to take silodosin even if you feel well. Do not stop taking silodosin without talking to your doctor.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
