effetti collaterali finasteride

What are the potential side effects of finasteride treatment?


Propecia is generally well tolerated, with very few individuals reporting any side effects. Side effects that were reported during clinical trials for prostate and alopecia treatment are listed below:

– Breast enlargement and pain on the nipples
– Skin rashes
– Swelling of the lips

All are rare events, but should be reported to your doctor as soon as you are aware of them.

The following side effects are rare and usually go away during treatment as your body adjusts to the medicine.


However, you should check with your doctor if any of the following side effects persist:

– Abdominal pain
– Back pain
– Decreased libido (decreased interest in sex)
– Diarrhea
– Dizziness, headache
– Impotence (inability to have or keep an erection)
– Decreased volume of sperm (decreased amount of semen)

A decrease in the amount of semen during ejaculation should not affect your sexual performance nor is it a sign of any change in fertility.
Propecia is well tolerated in doses of up to 80 mg a day, as is used by some individuals with benign prostatic hyperplasia without any apparent increase in side effects.

Note that there is no point taking high doses finasteride for androgenetic alopecia as it has been shown that there is no significant improvement in response when comparing 1 mg finasteride to 5 mg finasteride.
