1. What Finasteride is and what it is used for
Finasteride contains a medicine called finasteride. This belongs to a group of medicines
called Type II ‘5-alpha reductase inhibitors’.
Finasteride is used for the treatment of male pattern hair loss (also known as
androgenetic alopecia). Finasteride 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 Finasteride.
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 skin.
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 Finasteride work?
Finasteride 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.
2. What you need to know before you take Finasteride
Do not take Finasteride:
 If you are a woman (because this medicine is for men). It has been shown in
clinical trials that Finasteride does not work in women with hair loss.
 If you are allergic (hypersensitive) to finasteride or any of the other ingredients
of this medicine (listed in Section 6).
 If you are already taking finasteride or dutasteride used for a prostate problem
called benign prostatic hyperplasia (BPH).
Do not take Finasteride if any of the above apply to you. If you are not sure, talk to your
doctor or pharmacist.
Warnings and Precautions
Talk to your doctor or pharmacist before taking Finasteride if:

You are going to have a blood test for prostate cancer called PSA (prostatespecific antigen). This is because Finasteride can affect the result of this test.
Mood alterations and depression: Mood alterations such as depressed mood,
depression and, less frequently, suicidal thoughts have been reported in
patients treated with Finasteride. If you experience any of these symptoms stop
taking Finasteride and contact your doctor for further medical advice as soon as

Effects on fertility
Infertility has been reported in men who took finasteride for long time and had other
risk factors that may affect fertility. Normalisation or improvement of seminal quality
has been reported after discontinuation of finasteride. Long-term clinical studies about
the effects of finasteride on fertility in men have not been conducted.
Breast Cancer
See section 4
Children and adolescents
Finasteride 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 Finasteride
Tell your doctor or pharmacist if you are taking, have recently taken or might take any
other medicines. Finasteride does not usually affect other medicines.
 Do not take Finasteride if you are already taking finasteride or dustasteride,
used for a prostate problem called benign prostatic hyperplasia (BPH).
 No information is available about the use of Finasteride with minoxidil, another
type of medicine for male pattern hair loss which is applied to the head.
Pregnancy, breast feeding and fertility
Finasteride is for the treatment of male pattern hair loss in men only. For effects on
fertility see section 2.

Finasteride should not be taken by women.
Do not touch crushed or broken Finasteride tablets if you are a woman who is
pregnant or planning to become pregnant (whole tablets are coated to stop
contact with the medicine during normal use). This is because this medicine
may affect the baby’s sex organs.
If a woman who is pregnant comes into contact with crushed or broken
Finasteride tablets, speak to your doctor.

your doctor or pharmacist if you are not sure.

The recommended dose is one tablet each day. The tablet can be taken with or

If you take too many tablets by mistake, contact your doctor immediately. Finasteride
will not work faster or better if you take it more than once a day.
If you forget to take Finasteride

Do not take a double dose to make up for a forgotten dose.

If you stop taking Finasteride
It may take 3 to 6 months for the full effect to develop. It is important to keep taking
Finasteride for as long as your doctor tells you. If you stop taking Finasteride, you are
likely to lose the hair you have gained within 9 to 12 months.

What else should you know about Finasteride?
Finasteride can also be used for a type of prostate problem called ‘benign prostatic
hyperplasia’ or BPH. Information collected from a clinical trial in men taking finasteride
5 mg (a dose 5 times higher than Finasteride) 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.

If you would like further information about the tumour grading system or this trial,
please talk to your doctor.
