NOTICE: This Consumer Medicine Information (CMI) is intended for persons living in Australia. This page contains answers to some common questions about Flutamin. It does not contain all the information that is known about Flutamin. It does not take the place of talking to your doctor or pharmacist. All medicines have risks and benefits.

What Flutamin is used for

Flutamin is used together with another medicine (LHRH agonists) to treat cancer of the prostate gland. It is also used to prevent "flare" associated with LHRH agonists use.
Flutamin contains the active ingredient flutamide, which is a non-steroidal antiandrogen. This medicine works by blocking the effects of androgens, male hormones, which prostate cancer cells need to grow.
Ask your doctor if you have any questions about why Flutamin has been prescribed for you.
Your doctor may have prescribed Flutamin for another reason.
Flutamin is available only with a doctor's prescription.
There is no evidence that Flutamin is addictive.
As prostate cancer only occurs in men, this medicine therefore should not be used in women.

itching of the skin
dark urine (amber or yellow-green urine is not a cause for concern)

tenderness in the right upper stomach
constant tiredness or "flu-like" symptoms.

The following tips may help if you are experiencing diarrhoea:
drink plenty of fluids
cut down on dairy products
try eating smaller food portions
eat more carbohydrates
in consultation with your doctor, you may also try taking medication to manage diarrhoea.
Since a variety of medications can cause diarrhoea, it is important to tell your physician about all the medicines you take, including those that are non-prescription.
Any therapy that stops the production of male hormones, such as medical or surgical castration, will affect your sex drive. However, the addition of Flutamin to medical castration will not add to this effect. It is important to remember that the reduction of androgen levels may make erection more difficult. If you experience problems, please ask your doctor about available treatment options.
Check with your doctor as soon as possible if you have any problems while taking Flutamin even if you do not think the problems are connected with the medicine or are not listed in this leaflet.
Tell your doctor if you notice anything that is making you feel unwell.
This is not a complete list of all possible side effects.
