1. 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’. Your doctor has prescribed Propecia because you have 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 Propecia. 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 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.
2. Before you take Propecia
Do not take Propecia if:
• you are a woman (because this medicine is for men). It has been shown in clinical
trials that Propecia does not work in women with hair loss. • you are allergic (hypersensitive) to finasteride or any of the other ingredients (listed • you are already taking finasteride or dutasteride used for a prostate problem called Do not take Propecia if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist. Propecia should not be used in children. Take special care with Propecia
Check with your doctor or pharmacist before taking your medicine if you are going to
have a blood test for prostate cancer called PSA (prostate-specific antigen). This is
because Propecia can affect the result of this test.
Taking other medicines
Propecia does not usually affect other medicines. Always tell your doctor about all
medicines you are taking or planning to take, including any obtained without a
prescription.
Do not take Propecia if you are already taking finasteride or dustasteride, used for a prostate problem called benign prostatic hyperplasia (BPH). Taking Propecia with food and drink
Propecia can be taken with or without food.
Pregnancy and Breast feeding
• Propecia should not be taken by women. • Do not touch crushed or broken Propecia 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).

Using other medicine for male pattern hair loss with Propecia

4. Possible side effects
Like all medicines, Propecia can cause side effects, although not everybody gets them.
The following side effects may happen with this medicine:

Allergic reactions
If you have an allergic reaction, stop taking it and see your doctor straight away. The
signs may include:
• Skin rashes, itching, or lumps under your skin (hives)
• Swelling of lips, face, tongue or throat • breathing difficulties.
Other side effects may include:
• you may be unable to have an erection (impotence)
• you may have less desire to have sex • you may have problems with ejaculation, for example a decrease in the amount of semen released during sex. This decrease in the amount of semen does not appear to affect normal sexual function. These side effects above may disappear after a while if you continue taking Propecia. If these symptoms persist, they usually resolve after stopping Propecia. Other side effects reported in men are: • breast swelling or tenderness • palpitations (feeling your heartbeat) • Changes in the way your liver is working, which can be shown by a blood test • persistent difficulty having an erection after discontinuation of treatment • 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.
You should promptly report to your doctor any changes in your breast tissue such as
lumps, pain, enlargement or nipple discharge as these may be signs of a serious
condition, such as breast cancer.
If any of these side effects gets serious, or if you notice any side effects not listed on
this leaflet please tell your doctor or pharmacist. It will help if you make a note of
what happened, when it started and how long it lasted.

Will the use of Propecia affect the hair on other parts of your body?

What else should you know about Propecia?
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 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. If you would like further information about the tumour grading system or this trial,
please talk to your doctor.
