• 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.

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.

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).

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

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

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

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.

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.

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

Flutamide must not be given to children.

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

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.

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

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.

Do not stop taking this medicine, even if you are feeling well, unless your doctor tells you to.
