Downsides
  • You need to take Proscar (finasteride) for at least 6 months before your prostate gets small enough for symptoms to improve.
  • You cannot donate blood while using this drug nor for 1 month after stopping.
  • This drug may increase the risk of a type of prostate cancer.
  • Proscar (finasteride) may lower sperm counts in men, but they remained within the normal range and this side effect was reversible once Proscar (finasteride) was stopped.
