1. What Proscar is and what it is used for
Proscar contains a medicine called finasteride. This belongs to a
group of medicines called ‘5-alpha reductase inhibitors’.
Proscar shrinks the prostate gland in men when it is swollen. The
prostate gland is found underneath the bladder (but only in men).
It produces the fluid found in semen. A swollen prostate gland
can lead to a condition called ‘benign prostatic hyperplasia’ or
What is BPH?
If you have BPH it means that your prostate gland is swollen. It
can press on the tube that urine passes through, on its way out
of your body.
This can lead to problems such as:

feeling like you need to pass urine more often, especially at

feeling that you must pass urine right away

finding it difficult to start passing urine

when you pass urine the flow of urine is weak

when you pass urine the flow stops and starts

feeling that you cannot empty your bladder completely.
In some men, BPH can lead to more serious problems, such as:

urinary tract infections

a sudden inability to pass urine

the need for surgery.
What else should you know about BPH?

BPH is not cancer and does not lead to cancer, but the two
conditions can be present at the same time.

Before you start Proscar, your doctor will do some simple
tests to check whether you have prostate cancer.
Talk to your doctor if you have any questions about this.
2. What you need to know before you take Proscar
Do not take Proscar:

if you are a woman (because this medicine is for men)

if you are allergic (hypersensitive) to finasteride or any of the
other ingredients of this medicine (listed in Section 6).
Do not take Proscar 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 Proscar if:

your partner is pregnant or planning to become pregnant.
You should use a condom or other barrier method of
contraception when taking Proscar. This is because your
semen could contain a tiny amount of the drug and may
affect the normal development of the baby’s sex organs.

You are going to have a blood test called PSA. This is
because Proscar can affect the results of this test.
If you are not sure, talk to your doctor or pharmacist before
taking Proscar.
Mood alterations and depression
Mood alterations such as depressed mood, depression and, less
frequently, suicidal thoughts have been reported in patients
treated with Proscar. If you experience any of these symptoms
contact your doctor for further medical advice as soon as

Proscar should not be used in children.
Taking other medicines
Tell your doctor or pharmacist if you are taking, have recently
taken or might take any other medicines. Proscar does not
usually affect other medicines.
Taking Proscar with food and drink
Proscar can be taken with or without food.
Pregnancy and breast feeding

Proscar should not be taken by women.

Do not touch crushed or broken Proscar 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 normal development of the baby’s sex organs.

If a woman who is pregnant comes into contact with crushed
or broken Proscar tablets, speak to your doctor.
