Flutamide belongs to a group of medicines
called anti-androgens. It blocks the effect of
testosterone (male sex hormone) in the body.
Flutamide is used to treat prostate cancer. It
may be taken with another medicine (called
a LHRH agonist) that decreases the levels of
testosterone. Flutamide can also be used after
surgical castration.

Do not take Flutamide:

• if you are allergic to flutamide or any of the
other ingredients of this medicine (listed in
section 6).
Flutamide treats a condition found only
in men. It must not be given to women
or children.

Warnings and precautions

Talk to your doctor or pharmacist before
taking Flutamide if you:
• have liver problems. Your doctor will
check your liver function before and
during treatment.
• have kidney problems.
• have heart disease.
• are at risk of osteoporosis such as if you
are a long term smoker or drinker, have
a family history of osteoporosis or are
taking medicines to stop epileptic fits
(antiepileptics) or medicines to relieve
inflammation (corticosteroids) or have
osteoporosis (brittle bones) as Flutamide
can increase the risk of bone fractures. Your
doctor will measure your bone mineral
density (BMD) to check you are not at risk;
at the beginning of your treatment and
then at least on a yearly basis.
• suffer from chest problems such
as breathlessness.
• are diabetic.
• have any heart or blood vessel conditions,
including heart rhythm problems
(arrhythmia), or are being treated with
medicines for these conditions. The risk of
heart rhythm problems may be increased
when using Flutamide.
If you are taking Flutamide long-term you
may also have your sperm count checked if it
is appropriate.
While taking this medicine you should use an
effective barrier method of contraception i.e.
condom when engaging in sexual activity.

Other medicines and Flutamide

Tell your doctor or pharmacist if you are taking,
have recently taken or might take any other
medicines, including medicines obtained
without a prescription, especially any of
the following:
• medicines that thin the blood such
as warfarin
• theophylline, for breathing problems
• medicines that may cause damage
to the liver
• medicines that affect the electrical activity
of your heart
• leuprorelin, a medicine used to treat
some cancers

Flutamide might interfere with some
medicines used to treat heart rhythm
problems (e.g. quinidine, procainamide,
amiodarone and sotalol) or might increase
the risk of heart rhythm problems when
used with some other drugs (e.g. methadone
(used for pain relief and part of drug
addiction detoxification), moxifloxacin (an
antibiotic), antipsychotics used for serious
mental illnesses).

Flutamide with alcohol

You should not drink large quantities of
alcohol while being treated with this medicine.

Pregnancy and breast-feeding

Flutamide must not be prescribed to women
and therefore must not be given to pregnant
or breast-feeding mothers.

Driving and using machines

If you have had your testicles removed
(castrated) you will not be given a
LHRH agonist.

Use in children

Flutamide must not be given to children.

Patients with liver problems

If you have liver problems your doctor will
arrange for you to have regular blood tests.

If you take more Flutamide than
you should

You may suffer from methaemoglobinaemia
(where your blood cannot deliver as much
oxygen to your body as normal). Symptoms
can include cyanosis (bluish colouring of
the skin), blood that is darker than usual,
headache, weakness, confusion, chest pain
or vomiting.

Flutamide may cause tiredness, dizziness or
confusion. Do not drive or operate machinery
if it happens to you.

If you take more medicine than you should,
tell your doctor immediately or go to your
nearest hospital emergency department.

Flutamide tablets contain lactose

If you forget to take Flutamide

If you have been told by your doctor that you
have an intolerance to some sugars, such as
lactose, contact your doctor before taking
this medicine.

Always take this medicine exactly as your
doctor or pharmacist has told you. Check with
your doctor or pharmacist if you are not sure.
• Take the tablets with a glass of water
preferably after food every 8 hours.
• Do not chew the tablets. If you do, there is
a danger you could overdose because this
medicine will be absorbed into your body
too quickly.
• The score line is only there to help you
break the tablet if you have difficulty
swallowing it whole. It is not for dividing
tablets into equal doses.

Adults (including older people)

The recommended dose is one tablet three
times daily, every 8 hours.
You may also be given another medicine with
your Flutamide called a LHRH agonist. LHRH
agonists (e.g. goserelin, buserelin) are given
by injection. In that case, it is very important
that the two medicines are taken as directed.
You will start your Flutamide treatment either
at the same time as or at least a day before
taking the LHRH agonist.

Take it as soon as you remember unless it
is almost time for your next tablet. If this
happens, skip the missed tablet and take the
next tablet on time. Do not take a double
dose to make up for a forgotten tablet.

If you stop taking Flutamide

Do not stop taking this medicine, even if you
are feeling well, unless your doctor tells you to.
If you have any further questions on the use of
this medicine, ask your doctor or pharmacist.

cause side effects, although not everybody
gets them.
