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. WHAT YOU NEED TO KNOW BEFORE YOU USE ZOLADEX
Do not use Zoladex:
• 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).
Do not have Zoladex if any of the above apply to you. If you are not sure,
talk to your doctor, pharmacist or nurse before having Zoladex.
Warnings and precautions
If you go into hospital, tell the medical staff that you are having Zoladex.
Talk to your doctor, pharmacist or nurse before using Zoladex:
• if you have high blood pressure.
• if you 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 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) 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
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.
