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.

Information for women
Talk to your doctor, pharmacist or nurse before using 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.
Other medicines and Zoladex
Tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take
any other medicines. This includes medicines that you buy without a prescription and
herbal medicines.
Zoladex 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).
Pregnancy, breast-feeding and fertility
• 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 to use Zoladex
• The Zoladex 3.6 mg Implant 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.

2. What you need to know before you use Zoladex

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).

Do not use Zoladex:

4. Possible side effects

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

• if you are allergic to goserelin or any of the other ingredients of this medicine (listed
in section 6).
• if you are pregnant or breast-feeding (see the section on ‘Pregnancy and
breast-feeding’ below).

doctor, pharmacist or nurse before having Zoladex.

(arrhythmia), or are being treated with medicines for these conditions. The risk of
heart rhythm problems may be increased when using Zoladex.
