Fincar is a brand of finasteride 5 mg, commonly used for enlarged prostate (BPH) and sometimes used off-label in hair-loss routines.
Many users tolerate treatment well, but some may experience sexual, hormonal, or other side effects. Understanding possible reactions helps guide safer use.
Most side effects are mild and may improve with continued treatment or after stopping under medical supervision.
Because Fincar lowers DHT levels, some men may notice sexual changes.
Less common reactions may involve hormonal sensitivity.
Some users report persistent sexual or mood-related symptoms after stopping treatment. Research findings are mixed, and not every case confirms direct causation.
If symptoms continue, medical review is recommended.
