finasteride androgenic alopecia dihydrotestosterone DHT orthostatic hypotension gynecomastia prostate-specific antigen PSA Propecia

TLDR Finasteride treats hair loss but may cause side effects like low libido and dizziness.

This article discusses the use of finasteride in treating androgenic alopecia, a common condition affecting approximately 50% of men by the age of 50 years. Finasteride is an FDA-approved medication that inhibits the enzyme responsible for the production of dihydrotestosterone (DHT), which is a hormone that contributes to hair loss. The medication is available in 5-mg and 1-mg tablets, with the former being less expensive. Adverse effects include orthostatic hypotension, dizziness, decreased libido, impotence, ejaculatory disorder, weakness, gynecomastia, and decreased ejaculate volume. The document also provides warnings and precautions for the use of finasteride, including its potential effects on pregnancy, prostate-specific antigen testing, sexual side effects, blood pressure, and breast lumps.
