1. WHAT FLUTAMIDE IS AND WHAT IT IS USED FOR

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.

2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE FLUTAMIDE
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

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

Flutamide tablets contain lactose and sodium

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’.

3. HOW TO TAKE FLUTAMIDE

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.

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.

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

If you forget to take Flutamide

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.
