In women, Zoladex LA is used to:

• Treat early and advanced breast cancer that is hormone dependent.

In women, Zoladex LA 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).

• 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 LA.
• 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).

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 LA 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).
