What this medicine is used for
Finasteride is for use by men only.
Finasteride is used to treat a medical condition in men called benign prostatic hyperplasia (BPH). BPH is a condition where your prostate gland (which is near your bladder) has become bigger, making it more difficult for you to pass urine. This can lead to symptoms such as:
weak or interrupted stream of urine
feeling that you cannot empty your bladder completely
a delay before you start to pass urine
needing to pass urine often, especially at night
feeling that you must pass urine right away
BPH occurs only in men and is common over the age of 50 years. The prostate gland takes years to grow. Therefore, the symptoms of BPH take a long time to develop. In some men, BPH can lead to serious problems, including urinary tract infections and the sudden inability to pass urine at all (acute urinary retention). BPH may also require surgery to improve the flow of urine.
How it works
Finasteride works by slowly reducing the size of your prostate gland. This may lead to gradual improvement in your urine flow and other symptoms over several months. Finasteride also helps reduce the risk of developing a sudden inability to pass urine and the need for surgery. This may happen whether or not you notice any improvement or change in your symptoms.

Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor’s prescription.

Women who are pregnant or may be pregnant must not take finasteride tablets, handle crushed or broken tablets or handle tablets with wet hands. If this occurs, her doctor must be consulted immediately.

How much to take
The usual dose is one tablet taken once each day.
How to take it

When to take it

It does not matter if you take it before, with or after food.
How long to take it for
Finasteride shrinks the prostate gland slowly. Therefore, you may need to take this medicine for 6 months or longer to see whether it helps you. If it does help your symptoms, you may need to take this medicine every day.
Continue taking your medicine for as long as your doctor prescribes. If you stop taking the medicine the prostate gland is likely to grow again.
Make sure you have enough to last over weekends and holidays.
If you forget to take it
If it is almost time to take your next dose, skip the missed dose and take your next dose at the usual time.
Otherwise take it as soon as you remember and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for missed doses.
This may increase the chance of you experiencing side effects.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice or go to the Emergency Department at your nearest hospital if you think that you or anyone else may have taken too much of this medicine. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
While you are taking this medicine
Things you must do
If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking finasteride.
Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.
Tell your doctor if you are about to have any blood tests.
Finasteride can affect the results of a blood test required to measure your PSA (prostate-specific antigen) levels.
Go to your doctor for regular checkups, including a physical check for prostate cancer once a year if you are over 50.
Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects.
While BPH is not cancer and does not lead to cancer, the two conditions can exist at the same time. Finasteride is used for BPH, not prostate cancer.
Things you must not do
Do not give this medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or change your dosage without first checking with your doctor.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking finasteride.
Finasteride helps most men with BPH, but it may have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious but most of the time they are not.
Do not be alarmed by the following lists of side effects. You may not experience any of them.
Tell your doctor or pharmacist if you notice any of the following and they worry you:
impotence (inability to have an erection)
less desire for sex
changes or problems with ejaculation, such as decreased amount of semen released during sex (this decrease does not appear to interfere with normal sexual function)
These are the more common side effects of finasteride. For the most part these have been mild. In some cases, these side effects disappeared while the patient continued to take finasteride. If symptoms persisted, they usually resolved on stopping the tablets.
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 finasteride.
Tell your doctor as soon as possible 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 nettle rash (pinkish, itchy swellings on the skin)
blood in semen
depression (feeling of severe sadness and unworthiness) including suicidal thoughts
The above list includes more serious side effects. You may need medical attention. Most of these side effects are rare.
If you experience any of the following, stop taking your medicine and contact your doctor immediately or go to the Emergency Department at your nearest hospital:
shortness of breath, wheezing or difficulty breathing
rash, itching or hives on the skin
swelling of the lips, tongue, throat or face
These may be symptoms of a serious allergic reaction to finasteride. These are very serious side effects and are usually very rare. You may need urgent medical attention or hospitalisation.
Other side effects not listed above may occur in some patients.
