FINASTERIDE SIDE EFFECTS – Memory, Anxiety, in Females


Finasteride Side effects in Females and Male


Finasteride Side effects

Finasteride is an anti-androgen agent used to treat benign prostatic hyperplasia and male pattern baldness. This medication works by inhibiting the 5 alpha reductase enzyme that converts the male sex hormone testosterone into its more potent form, dihydrotestosterone (DHT).

For finasteride side effects, the commonly reported side effects of finasteride include: impotence and decreased libido. Other side effects include: impotence and decreased libido. See below for a comprehensive list of adverse effects.

The side effects seen with this drug are therefore related to its anti-androgenic effects. Since both benign prostatic hyperplasia and male pattern baldness require long-term and continuous use of the drug, the risk of side effects is high.

One 12 month clinical trial of 5 mg finasteride versus placebo in 3000 patients showed that the side effects associated with finasteride include:

  • Decreased labido (at 5% versus 3%)
  • Erectile dysfunction (at 8% versus 3%)
  • Ejaculation disorder (at 2.0% versus 0.6%)


Benign prostatic hyperplasia

Patients taking finasteride to treat benign prostatic hyperplasia may find that symptoms such as difficulty urinating, increased urination frequency and decreased urinary flow improve after around six months of treatment. These beneficial effects, however, are reversed and symptoms worsen when the medication is discontinued.

Male pattern baldness

Finasteride has also been shown to benefit men with mild to moderate hair loss. Again, the medication is only effective for as long as it is used, with the therapeutic effects being lost within 6 to 12 months after discontinuation of the therapy.


Pregnant women

Finasteride causes defects of the sexual organs in the male fetus. Pregnant women or women who are likely to be pregnant should therefore be careful not to handle crushed finasteride tablets in order to avoid its absorption via the skin.


In addition to its needed effects, some unwanted effects may be caused by finasteride. In the event that any of these side effects do occur, they may require medical attention.
