What Anandron is used for
Anandron is a medicine for treating prostate cancer in men. It contains the active ingredient Nilutamide.
Anandron belongs to a family of medicines called non-steroidal anti-androgens. These medicines work by blocking the effect of androgen hormones that are naturally produced by your body. Prostate cancer cells are dependent on these hormones, and blocking their effect is intended to stop the growth of the cancer.
Anandron is more effective when used at the same time as other medicines known generally as LHRH agonists or, alternatively, following surgery designed to treat prostate cancer.
Your doctor may have prescribed Anandron for another reason.
Ask your doctor if you have any questions about why Anandron has been prescribed for you.
Anandron is available only with a doctor's prescription.

How to take Anandron
How much to take
Follow all directions given to you by your doctor and pharmacist carefully. These directions may differ from the information contained in this leaflet.
The usual dosage of Anandron is one tablet twice daily (or two tablets once daily) for the first four weeks and then one tablet once daily thereafter.
If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.
How to take it
You should swallow each tablet whole with some water. Do not chew them.
When to take it
You can take Anandron with or without food.
How long to take it for
Do not take Anandron for longer than your doctor says. If you are not sure how long to take Anandron, ask your doctor.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking your tablets as you would normally. Do not take a double dose to make up for the dose that you missed.
If you are not sure whether to skip the dose, talk to your doctor or pharmacist.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (Telephone 13 11 26), or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much Anandron. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
While you are taking Anandron
Things you must do
Tell your doctor immediately if you experience any breathing problems or a worsening of a pre-existing breathing problem.
Symptoms may include shortness of breath, coughing, chest pain or fever.
Tell your doctor immediately if you experience nausea, vomiting, abdominal pain and jaundice (yellow eyes/skin).
If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking Anandron.
Things you must not do
Do not give Anandron to anyone else, even if they have the same condition as you.
Do not take Anandron to treat any other complaints unless your doctor says to.
You should not stop taking Anandron without consulting your doctor first.
Things to be careful of
Be careful driving or operating machinery until you know how Anandron affects you.
Anandron may cause dizziness or light-headedness in some people. Make sure you know how you react to Anandron before you drive a car, operate machinery or do anything else that could be dangerous if you are dizzy or light-headed. If you drink alcohol, dizziness or light-headedness may be worse.
Anandron helps most people with prostate cancer, but it may have unwanted side-effects in some people.
All medicines may cause side effects. Sometimes they are serious, but most of the time they are not. You may need medical treatment for some of the side-effects that have been seen in patients taking Anandron.
Most side effects caused by Anandron happen early in the course of treatment and usually lessen after four weeks when the dose is normally reduced to one tablet daily. The most common side effect affects the eyes and makes it difficult to adapt to darkness. This problem is almost always temporary and may be improved by wearing tinted glasses (eg. sunglasses). Until your eyes get used to darkness, you should not drive at night or through tunnels in bright light.
Tell your doctor if you experience any of the following side effects and it worries you:
nausea or vomiting
difficulty adapting to changes in light
Your doctor may be able to adjust your treatment or give you advice to make these side effects less troublesome.
Tell your doctor immediately if you experience any of the following:
any new breathing problem or chest pain, or a worsening of a pre-existing breathing problem
jaundice (yellow eyes/skin) possibly with nausea, vomiting and abdominal pain
allergic reactions such as asthma, wheezing, shortness of breath, swelling of the face, lips or tongue, hives, itching, skin rash or fainting
You may need urgent medical attention for these rare serious side effects.
Other side effects not listed above may occur in some patients, so you should tell your doctor if you feel unwell while taking Anandron.
Do not be alarmed by this list of possible side effects.
You may not experience any of them. Ask your doctor or pharmacist to answer any questions you may have.
After using Anandron
Keep your tablets in the blister strip until it is time to take one.
If you take the tablets out of the blister strip, they may not keep as well.
Store Anandron tablets in a cool dry place where the temperature stays below 30°C. Do not store them or any other medicine in the bathroom or near a sink. Do not leave the tablets in the car or on window sills. Heat and dampness can destroy some medicines.
Keep Anandron where children cannot reach it.
A locked cupboard at least one-and-a-half metres (about 5 feet) above the ground is a good place to store medicines.
If your doctor tells you to stop taking Anandron tablets or if the tablets have passed their expiry date, ask your pharmacist what to do with any tablets that are left over.
