What PROPECIA is used for
PROPECIA is for use by men only.
PROPECIA is used to treat men with male pattern hair loss to increase hair growth
on the scalp and to prevent further hair loss.
Male pattern hair loss (also known as androgenetic alopecia) is a common condition
in which men experience thinning of the hair on the scalp. This often results in a
receding hair line and/or balding on the top of the head. These changes typically
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.
Male pattern hair loss is thought to be caused by a combination of family history
(heredity) and production of a particular male hormone, called dihydrotestosterone
(DHT). Men with male pattern hair loss have more DHT in the balding part of their
scalp than in other parts, resulting in increased hair loss.
How PROPECIA works
PROPECIA specifically lowers the levels of DHT in the scalp, thus helping to reverse
the balding process.
PROPECIA does not affect hair on other parts of the body.
Men with mild to moderate, but not complete, hair loss can expect to benefit from
the use of PROPECIA. In women who were studied, PROPECIA was not effective in the
treatment of hair loss (androgenetic alopecia).
There should be no need to change your usual hair care routine (for example, shampooing
or haircuts) because you are taking PROPECIA.
PROPECIA is not addictive.

If the active ingredient in PROPECIA is absorbed after swallowing the tablet or through
the skin by a woman who is pregnant with a male baby, it may cause the male baby to
be born with abnormalities of the sex organs.
Whole tablets are coated to prevent contact with the active ingredient during normal
handling, provided that the tablets haven't been crushed or broken.
If a pregnant woman swallows PROPECIA, handles crushed or broken tablets or handles
tablets with wet hands, her doctor must be consulted immediately.
PROPECIA is for use by men only.
Before you start to take it
Tell your doctor if:
1. you have or have had any medical conditions
2. you have any allergies to any other medicines or any other substances, such as foods,

Taking other medicines
Tell your doctor if you are taking any other medicines, including medicines that you
buy without a prescription from your pharmacy, supermarket or health food shop.

then go back to taking your tablet as you would normally.

How long to take it
Male pattern hair loss is a condition that develops over a long period of time. Because
it takes time for new hair to grow, you will not see immediate results. In general,
daily use for 3 months or more may be necessary before you notice increased hair growth
or prevention of further loss. Continue taking PROPECIA for as long as your doctor
If you stop taking it
If you stop taking the tablets your hair loss is likely to resume.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26)
for advice, if you think that you or anyone else may have taken too much PROPECIA.
Do this even if there are no signs of discomfort or poisoning.
While you are using PROPECIA
Things you must do

that you are taking PROPECIA.

Tell your doctor or pharmacist as soon as possible if you do not feel well while you
are taking PROPECIA.
PROPECIA helps most men with male pattern hair loss, but it may have unwanted side
effects in a few men. All medicines can have side effects. Sometimes they are serious,
most of the time they are not. You may need medical treatment if you get some of the
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
difficulty in achieving an erection that continues after stopping PROPECIA
less desire for sex that continued after stopping PROPECIA
decreased amount of semen released during sex (this decrease does not appear to interfere
with normal sexual function).
It is important to understand that, in clinical trials, these unwanted effects disappeared
in men who stopped taking PROPECIA, as well as in many men who continued treatment.
Problems with ejaculation that continue after stopping medication have been reported
infrequently. Tell your doctor if you notice this and it worries you.
Male infertility and/or poor quality of semen have been reported infrequently. Improvement
in the quality of semen has been reported after stopping PROPECIA.
Tell your doctor immediately if you notice any of the following:
breast swelling and/or tenderness
In rare cases, male breast cancer has been reported.
breast lumps, pain or discharge from the nipples.
skin rash, itchiness
hives or nettlerash (pinkish, itchy swellings on the skin)
blood in semen
depressions (feelings of severe sadness and unworthiness) including suicidal thoughts
These are uncommon side effects that have been reported with PROPECIA.
Tell your doctor immediately or go to accident and emergency at your nearest hospital
if the following happens:
swelling of the lips, tongue, throat or face
These may be symptoms of a serious allergic reaction to PROPECIA, which may cause
difficulty in swallowing or breathing. You may need urgent medical attention. Serious
side effects are rare.
Other side effects not listed above may occur in some men. Tell your doctor or pharmacist
if you notice any other unwanted effects.
After using PROPECIA
Keep your tablets in the blister pack until it is time to take them.
If you take the tablets out of the blister pack they may not keep well.
Never put the tablets in another box or container, as they might get mixed up.
Keep PROPECIA in a cool dry place where the temperature stays below 30°C. Do not store
it or any other medicine in the bathroom or near a sink.
Do not leave it in the car or on window sills.
Heat and dampness can destroy some medicines.
Keep it where children cannot reach it.
A locked cupboard at least one-and-a-half metres above the ground is a good place
to store medicines.
If your doctor tells you to stop taking the tablets, or the tablets have passed their
expiry date, ask your pharmacist what to do with any that are left over.
