6. Contents of the pack and other information
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 BPH.
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
This can lead to problems such as:
- feeling like you need to pass urine more often, especially at night
- 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.
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.

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.
Driving and using machines
Proscar is not likely to affect you being able to drive, use tools or machines.

Check with your doctor or pharmacist if you are not sure.
Taking this medicine
- The usual dose is one tablet each day.

doxazosin) to help control your BPH.

- If you forget to take a tablet, skip the missed dose.
- Take the next dose as usual.
- Do not take a double dose to make up for a forgotten dose.
If you stop taking Proscar
Your condition may show an early improvement after taking Proscar.
However, it may take at least six months for the full effect to develop. It is
important to keep taking Proscar for as long as your doctor tells you, even if
you do not feel any benefit straight away.
If you have any further questions on the use of this medicine, ask your
doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not
everybody gets them. The following side effects may happen with this
Allergic reactions
Stop using Proscar and immediately contact a doctor if you experience any
of the following symptoms:
- Swelling of face, lips, tongue or throat, difficulty swallowing and breathing

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.

Proscar should not be used in children.

These side effects above may disappear after a while if you continue taking
Proscar. If not, they usually resolve after stopping Proscar. Other side
effects reported in some men are:
- Breast swelling or tenderness

- Changes in the way your liver is working, which can be shown by a blood

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.

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.

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.

If any of the side effects get serious, or if you notice any side effects not
listed in 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.
