1. What Zoladex is and what it is used for

Zoladex contains a medicine called goserelin. This belongs to a group of medicines called ‘LHRH analogues'.

Use of Zoladex by men

In men, Zoladex is used to treat prostate cancer. It works by reducing the amount of ‘testosterone'

(a hormone) that is produced by your body.

Use of Zoladex by women

In women, Zoladex is used to:

•    Treat breast cancer.

•    Treat a condition called ‘endometriosis'. This is where cells normally only found in the lining of the womb (uterus) are found elsewhere in your body (normally on other structures near the womb).

•    Treat benign growths in the womb called ‘uterine fibroids'.

•    Make the lining of the womb thinner before you have an operation on your womb.

•    Help treat infertility (together with other medicines). It helps to control the release of eggs from the ovaries.

In women, Zoladex works by reducing the amount of 'oestrogen' (a hormone) that is produced by your body.

2. Before you are given Zoladex

Do not have Zoladex if:

•    You are allergic (hypersensitive) to goserelin or any of the other ingredients of this medicine (listed in Section 6: Further information).

•    You are pregnant or breast-feeding (see the section on ‘Pregnancy and breast-feeding' below).

Do not have Zoladex if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before having Zoladex.

Zoladex should not be given to children.

Take special care with Zoladex

If you go into hospital, tell the medical staff that you are having Zoladex.

Check with your doctor or nurse before you have Zoladex if:

•    You have high blood pressure.

There have been reports of depression in patients taking Zoladex which may be severe. If you are taking Zoladex and develop depressed mood, inform your doctor.

Information for men

Check with your doctor or nurse before you have Zoladex if:

•    You have problems passing urine (water) or problems with your back.

•    You have diabetes.

•    You have any condition that affects the strength of your bones, especially if you are a heavy drinker, a smoker, have a family history of osteoporosis (a condition that affects the strength of your bones) or take anticonvulsants (medicines for epilepsy or fits) or corticosteroids (steroids).

Medicines of this type can cause a reduction in bone calcium (thinning of bones).

Information for women

Check with your doctor or nurse before you have Zoladex if:

•    You have any condition that affects the strength of your bones, especially if you are a heavy drinker, a smoker, have a family history of osteoporosis (a condition that affects the strength of your bones), have a poor diet or take anticonvulsants (medicines for epilepsy or fits) or corticosteroids (steroids).

Medicines of this type can cause a reduction in bone calcium (thinning of bones). This may improve when treatment is stopped.

If you are having Zoladex for endometriosis, your doctor may reduce the thinning of the bones by giving you other medicines as well.

Taking other medicines

Please tell your doctor or nurse if you are taking or have recently taken any other medicines. This includes medicines that you buy without a prescription and herbal medicines.

Pregnancy and breast-feeding

•    Do not have Zoladex if you are pregnant or breast-feeding.

•    Do not have Zoladex if you are trying to get pregnant (unless Zoladex is being used as part of a treatment for infertility).

•    Do not use ‘the pill' (oral contraceptives) while you are having Zoladex.

Use barrier methods of contraception, such as the condom or diaphragm (cap).

Driving and using machines

Zoladex is not likely to affect you being able to drive or use any tools or machines.

3. How Zoladex will be given

•    The Zoladex 3.6mg injection will be injected under the skin on your stomach every four weeks (28 days). This will be done by your doctor or nurse.

•    It is important that you keep having Zoladex treatment, even if you are feeling well.

•    Keep having this treatment until your doctor decides that it is time for you to stop.

Your next appointment

•    You should be given a Zoladex injection every 28 days.

•    Always remind the doctor or nurse to set up an appointment for your next injection.

•    If you are given an appointment for your next injection which is earlier or later than 28 days from your last injection, tell your doctor or nurse.

•    If it has been more than 28 days since your last injection, contact your doctor or nurse so that you can receive your injection as soon as possible.

Information for women

•    If you are having Zoladex for uterine fibroids and you have anaemia (low levels of red blood cells or haemoglobin), your doctor may give you an iron supplement.

•    The length of your treatment with Zoladex will depend on what you are having it for:

-    To treat uterine fibroids, you should only have Zoladex for up to three months.

-    To treat endometriosis, you should only have Zoladex for up to six months.

-    To make the lining of your uterus thinner before an operation on your womb, you should only have Zoladex for one or two months (four or eight weeks).
