1. What is Propecia and what is it used for
Propecia is a film-coated tablet that contains the active substance finasteride.
Finasteride inhibits the activity of 5α-reductase type II, an enzyme involved in the metabolism of testosterone.
In men with androgenetic alopecia, finasteride reduces the concentration in the body of the testosterone metabolite that contributes to male pattern hair loss (androgenetic alopecia).
The medicine slows down the process of hair follicle miniaturization on the scalp, leading to a reversal of the hair loss process. The best treatment results are achieved in men with mild to moderate hair loss.
Finasteride does not have an effect on the treatment of androgenetic alopecia in women.
Indications for use
Propecia is indicated for the treatment of male pattern hair loss (androgenetic alopecia). It is used in men to increase hair growth and prevent further hair loss.
The medicine can only be used in men.
The medicine is not intended for use in women and children.
2. Important information before taking Propecia
When not to take Propecia
- in women,
- if the patient is allergic to finasteride or any of the other ingredients of this medicine (listed in section 6),
- in men taking finasteride or other 5α-reductase type II inhibitors for the treatment of benign prostatic hyperplasia or other conditions.
Warnings and precautions
Before starting to take Propecia, discuss it with your doctor or pharmacist.
Effect on prostate-specific antigen (PSA)
Inform your doctor that you are taking Propecia if your prostate-specific antigen (PSA) blood levels are being checked.

Pregnancy, breastfeeding, and fertility
Pregnancy
Propecia is contraindicated in women.
Taking Propecia is contraindicated in women who are pregnant or suspected to be pregnant.
Handling damaged or crushed tablets can cause the medicine to be absorbed through the skin and lead to fetal developmental abnormalities in male fetuses.
Women who are pregnant or suspected to be pregnant, as well as women of childbearing age, should not handle crushed or damaged Propecia tablets.
Propecia tablets are film-coated, which prevents direct contact with the medicine, provided the tablets are not damaged or crushed.
Breastfeeding
Propecia is contraindicated in women.
Taking Propecia is contraindicated during breastfeeding.
Fertility
There are no data on the effect on fertility in humans.
There have been reports of infertility in men taking finasteride for a long time, who had other fertility risk factors. However, no studies have been conducted on the effect of finasteride on fertility in men.

Propecia contains lactose monohydrate
If you have previously been diagnosed with intolerance to some sugars, you should consult your doctor before taking the medicine.
Propecia contains sodium
The medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means the medicine is considered "sodium-free".
