Used primarily in the treatment of benign prostatic hyperplasia (BPH), it helps reduce the size of an enlarged prostate, alleviating symptoms such as difficulty in urination. It works by inhibiting the enzyme responsible for converting testosterone to dihydrotestosterone (DHT), a hormone that contributes to prostate growth. Additionally, it is sometimes prescribed to lower the risk of urinary retention and the need for prostate surgery. It may also be used in combination with other medications for managing hair loss in men, as DHT is linked to male pattern baldness. Regular monitoring is advised to assess its effectiveness and manage potential side effects.
