Rapaflo (silodosin [SYE-loh-DOE-sin]) is an alpha blocker primarily used to treat benign prostatic hyperplasia (BPH), also called an enlarged prostate. This medication relaxes prostate and bladder-related muscles to improve urination, urinary frequency, urinary urgency, and relieve pain making it helpful for some prostatitis patients.

Rapaflo may cause dizziness, light-headedness, and fainting.
Do not take this medication if you have severe kidney or liver problems. Your kidneys may need to be monitored while taking this drug if you have kidney disease, as the kidneys aid in removing this medication from the body.
