AVODART is a prescription medication used primarily for the treatment of benign prostatic hyperplasia (BPH) in men. This condition, commonly known as an enlarged prostate, can lead to uncomfortable urinary symptoms. AVODART works by inhibiting the conversion of testosterone to dihydrotestosterone (DHT), which is a key factor in prostate growth. By reducing DHT levels, AVODART helps to shrink the prostate, improving urinary flow and reducing the risk of urinary retention.
