Silodosin is used in men to treat symptoms of an enlarged prostate (benign prostatic hyperplasia, BPH). It does not reduce the size of the prostate, but it helps to relax the muscles of the prostate and the bladder. This helps relieve symptoms of BPH, such as difficulty starting to urinate, urinating without force, and the need to urinate frequently or urgently (including at night).
Silodosin belongs to a class of drugs known as alpha-blockers.
Do not use this medicine to treat high blood pressure.
