See section 4.

What Propecia is and what it is used for

Propecia contains a medicine called finasteride. This belongs to a
group of medicines called Type II ‘5-alpha reductase inhibitors’.
Propecia is used for the treatment of male pattern hair loss (also
known as androgenetic alopecia). Propecia increases hair growth on
the scalp and prevents further hair loss in men. Men with mild to
moderate, but not complete hair loss, can benefit from using
How does the hair on your head grow?
On average your hair grows about 1 centimetre (half an inch) each
month. Hair grows from hair follicles, which are located under your
A single scalp hair grows continuously for 2-4 years (growth phase)
and then stops growing for 2‑4 months (rest phase). After this the
hair falls out. In its place a new healthy hair begins to grow, and the
cycle is repeated. The hairs on your scalp are always in different
stages of this cycle so it is normal to lose scalp hair every day.
What is male pattern hair loss?
Male pattern hair loss is a common condition in which men
experience thinning of the hair on the scalp, often resulting in a
receding hairline and/or balding on the top of the head. This
condition is thought to be caused by a combination of genetic factors
and a particular hormone, DHT (dihydrotestosterone).
DHT causes a decrease in the growth phase and thinning of the hair
(see picture). This leads to male pattern hair loss. These changes
can start to occur in some men in their 20s and become more
common with age. Once hair loss has occurred over a long period of
time, the hair may be permanently lost.
How does Propecia work?
Propecia lowers the levels of DHT in the scalp. This helps to reverse
the balding process, leading to an increased hair growth and
prevention of further hair loss.

Children and adolescents
Propecia should not be used in children.
There are no data demonstrating efficacy or safety of finasteride in
children under the age of 18.
Other medicines and Propecia
Tell your doctor or pharmacist if you are taking, have recently taken
or might take any other medicines. Propecia does not usually affect
other medicines.
 Do not take Propecia if you are already taking finasteride or
dustasteride, used for a prostate problem called benign prostatic
hyperplasia (BPH).

minoxidil, another type of medicine for male pattern hair loss
which is applied to the head.
Pregnancy, breast feeding and fertility

only. For effects on fertility see section 2.

‘benign prostatic hyperplasia’ or BPH. Information collected from a
clinical trial in men taking finasteride 5 mg (a dose 5 times higher
than Propecia) for 7 years showed:
 the number of men who developed prostate cancer was lower in
men taking finasteride compared with those taking nothing
 the number of men who had a high score in a tumour grading
system was higher in some of those taking finasteride
compared to those taking nothing
 the effect of long-term use of finasteride on tumours of this kind
is unknown.
